Whether blood is given during menstruation, is it possible to be a donor these days, when it is better to donate blood


Can I be a donor?

Donating blood donation not only allows you to save the life of another person, but also update your body to the donor. Traditionally, women donate biological material much more often than men. Therefore, a quite reasonable question arises - is it possible to donate blood for donation during menstruation? Indeed, in the period of menstruation and donation, a woman loses a certain amount of blood. And for someone, this blood loss may be critical, but for someone it is quite acceptable. How to determine that donation during the menstruation period is contraindicated for this patient, and absolutely acceptable for the other? In this matter, you should be guided by the advice of experienced hematologists.

The reasons for the ban

According to doctors, blood donation during menstruation is undesirable. In confirmation, doctors cite weighty evidence. First, during menstruation, a woman feels slightly unwell, desire

sleep, weakness, pain in the abdomen. All these symptoms suggest the withdrawal of large amounts of hormones from the body, which go along with the menstrual flow. If an additional fluid loss in the form of transfusion is added to this state, the patient may lose consciousness.

It is important to remember that one of the main components of blood is hemoglobin. During menstruation, this indicator is significantly reduced by the action of hormones. This means that all organs receive much less oxygen. If during this period donate blood in large quantities, you can worsen your condition, since the level of hemoglobin will fall to critical levels.

Blood donation during menstruation is undesirable because of the reduced immunity of the woman. In the period of menstrual bleeding, the female body is more susceptible to infections. Given this fact, additional blood loss can aggravate the patient's condition.

It is impossible to make the delivery of a biological fluid painkillers, which girls often use during menstruation. Since any drug inevitably enters the bloodstream, the further use of biological material is prohibited.

In what cases donation is possible.

If a patient needs blood transfusions, and the only donor is a woman, then donation is possible. In this case, it is only necessary to make sure that the donor did not take drugs and does not experience painful sensations. Using blood for transfusion, it must be remembered that, nevertheless, the biological material taken during menstruation has fewer leukocytes, hemoglobin and red blood cells. If these indicators are not critical, blood can be used to save the patient.

Possible consequences

Girls wishing to donate blood need to remember that this should not be done before critical days. Considering that donation is an external influence on the circulatory system, such a procedure before menstruation may cause a delay. It is especially undesirable to donate biological material 3-5 days before the onset of menstruation, for girls whose cycle is irregular. Such a procedure may delay the start of the next cycle.

It happens that the monthly after donation come immediately. This is due to the hormonal disruption and stress that the woman experienced during the blood donation period. Such a situation is not related to the blood transfusion procedure, since it is more psycho-emotional in nature. This is not a critical case, and if desired, the girl will be able to become a donor again after two or three cycles. During this period, hemoglobin levels will be restored and transfusions will not adversely affect health.

Summing up

The girls wait for menstruation after the donation should be on time. As practice shows, this procedure is not

has a negative effect on the female body. Moreover, if you donate blood regularly no more than four times a year, you can significantly update the resources of the body. And so that donation does not lead to negative consequences, it should be remembered that the transfusion cannot be done before and during menstruation. In the rest of the time, donation will benefit not only the patient, but also the donor himself. So feel free to go to the procedure in order to save the life of a person.

What you need to know, donating blood during menstruation

During menstruation, the functional uterine layer is rejected. This process is accompanied by bleeding. The woman’s well-being is getting worse, there can be pressure drops and dizziness. This is due to changes in hormonal levels. Progesterone, which was produced by the corpus luteum in the luteal phase, decreases sharply during menstruation, affecting all vital processes.

During the period of critical days, changes in the hematopoietic system are noted. Some blood counts are rising, others are declining. Before interpreting the result, you should be familiar with the following facts:

  1. The level of red blood cells in the body increases dramatically. This reduces the number of leukocytes.
  2. In the early days of menstruation, an increase in ESR is observed. This phenomenon makes it possible to suspect the presence of an inflammatory process in the body.
  3. A coagulogram taken during menstruation will present an inaccurate result. The coagulability rate will be increased. In rare cases, the opposite is possible.
  4. The level of hemoglobin during menstruation falls below acceptable levels.
  5. Analysis of tumor markers can show a false positive result.
  6. Participation in the donor program during menstruation is not practiced. The collection of biomaterial adversely affects the well-being of women.

Is it allowed to take a blood test during menstruation?

The possibility of a similar procedure during menstruation is negotiated with your doctor. The probability of distortion of the results and the woman's well-being are taken into account.

This applies to some varieties of research:

  • determine the level of sugar
  • total blood count
  • allergy tests
  • PCR diagnostics,
  • immunological and biochemical analyzes,
  • coagulogram,
  • the definition of tumor markers.

General analysis

It is the basis of any diagnosis. It includes the determination of the level of red blood cells, platelets, leukocytes and hemoglobin. The result helps to identify pathological processes in the body. Indicators change significantly during menstruation, therefore It is not recommended to pass a general analysis during this period.. Even a small amount of discharge affects hemoglobin and other indicators. Intensive bleeding is the main reason for obtaining unreliable results.

An analysis that determines the presence of syphilis, hold during menstruation is not prohibited. The main function of the study is to detect pathogens. Their number does not change under the influence of hormones. The only reason that doctors prescribe the delivery of biomaterial after menstruation, is the lack of need to visit the treatment room again. All diagnostic measures that are needed for diagnosis can be carried out in one day.


The level of hormones in the body varies depending on the phases of the cycle. Therefore, for each type of analysis there are specific days for blood donation. The rates are calculated for women with an average duration of the menstrual cycle - 28 days. With deviations, the time of delivery is determined individually. Before visiting the treatment room, it is important to familiarize yourself with the following rules:

  1. Prolactin is recommended to take at the beginning of the menstrual cycle (from 3 to 5 days) or 23-26 days. With amenorrhea and pregnancy, blood is taken at any time.
  2. The level of follicle-stimulating hormone is determined from the 3rd to the 5th day of the cycle.
  3. There are two periods for blood donation for LH: from 3 to 8 days and from 21 to 23.
  4. The content of estradiol is determined on the 4-7 day cycle or after 6 after confirmed ovulation.
  5. The establishment of progesterone levels is carried out from 20 to 22 day of the menstrual cycle.

Before determining the hormonal background is recommended to abandon sexual intercourse, alcohol and active physical exertion. The reliability of the results can also be affected by the transferred stress. It stimulates the production of cortisol, which affects the amount of other hormones. Reception of hormonal drugs in the cycle of diagnostic procedures should be discontinued.

Other blood tests

During critical days, the female body becomes more susceptible to external stimuli, so the test for allergens will not show a reliable result. The level of sugar in the body is also recommended to check at the end of critical days. Immunological tests prescribed not earlier than one week after the completion of menstruation. PCR analysis and determination of tumor markers carried out strictly in the middle of the menstrual cycle.

Is it possible to be a donor during critical days

Regardless of how hardy a woman's body is, donating during menstruation is prohibited. Indicators of blood composition during this period will be distorted. Before submitting the biomaterial, it is necessary to undergo examination, excluding the presence of infectious diseases and pathologies of internal organs. Women are allowed to donate blood for transfusion no more than four times a year.

Implications of donating on critical days

The reasons for the prohibition include changing the coagulability of red blood cells and reducing hemoglobin levels. During blood sampling, a woman’s condition may deteriorate. In this case, headache, nausea and dizziness appear. There may be fainting and temporary loss of performance, as the body is under severe stress. In addition, the likelihood of bleeding increases.

Rate of results

Decoding of diagnostic tests is carried out on the basis of normal values. The diagnosis can only the attending physician. It takes into account factors that can cause changes in indicators. Below are the parameters of the established measures for each study:

  1. The level of sugar in the normal functioning of the body - 3.3-5.5 units.
  2. Leukocytes should be in an amount of from 3.5 to 10 thousand per 1 ml of blood liquid. Excess rate indicates the development of the inflammatory process.
  3. The norm of erythrocytes in a healthy organism is 0.85-1.05 units.
  4. The volume of red blood cells varies from 35 to 45%.
  5. Hemoglobin values ​​range from 120 to 160. A significant decrease in the results of the analysis indicates the development of anemia. With monthly rates decrease slightly.
  6. Estradiol ranges from 68 to 1269 pmol / L.
  7. The rate of progesterone in the luteal phase is from 6.99 to 56.93 nmol / l.
  8. The ratio of LH to FSH for women of reproductive age is about 1.3-2.5: 1. The decrease in the indicator indicates problems with the maturation of the egg, and the increased results are caused by polycystic ovary syndrome.
  9. Indicators of FSH at the beginning of the cycle are 3.5-12.5 units. During the ovulation period, the numbers increase to 25.

When is it better to donate blood

During the procedure, it is necessary to take into account all factors that may affect the result of the study. This will eliminate the need to re-visit the treatment room in case of an error. Indicators return to normal after about three days after the completion of menstrual flow. But doctors recommend to be safe, donating blood 6-7 days after the end of menstruation. It is equally important to observe the fundamental principles:

  1. The biomaterial is taken on an empty stomach, preferably in the morning.
  2. A few days before the procedure, you should refrain from eating fatty and spicy foods.
  3. The day before the collection of biomaterial should limit physical activity.
  4. Before giving blood for hormones, it is necessary to avoid stressful situations, since they affect the hormones.
  5. Pre-stops taking medicines that can distort the results of the study. This is discussed with the doctor without fail.
  6. You can not smoke and consume alcoholic beverages immediately before the analysis.


During menstruation to the body should be leniency. Physical exertion and experiences during this period are undesirable, therefore it is necessary to refuse to take tests. This will provide reliable information about the state of health and prevent negative consequences.

On the day of the collection of biomaterial about the slightest changes in well-being, you must inform the technician.

Is it possible to donate blood for analysis?

Experts agree that if there is an opportunity to postpone the physical examination or tests until the menstrual flow is over, then it is better to do it.

This applies to most biological fluid studies:

  • general,
  • biochemical,
  • on glucose,
  • to identify allergens,
  • immunological,
  • on tumor markers.

If you can not postpone the trip to the doctor, then you need to warn him about the situation. The interpretation of the results will be based on the information received.

Menstruation donation

Many people help others by participating in regular blood donations. Transfusion can save a person’s life in difficult situations. The volume of fluid that is withdrawn for donation is fixed and amounts to 200-450 ml, depending on the type of procedure.

The calculation of the optimal amount is based on the average blood volume in an adult. But a girl of fragile physique such donation can almost lead to a critical loss of this biological fluid.

If the blood index is reduced due to menstruation, then it may be difficult to get out of a state of acute loss. It takes about a month to restore the volume of the withdrawn, and with an additional factor, this process is delayed. In addition, there may be a failure in the hormonal system, impaired microcirculation.

Biochemical and other vein blood tests

Before carrying out operations of various scale, analysis is required, including clotting. Any surgery is performed with a violation of the skin and mucous membranes, and with an increase in this parameter, massive bleeding may begin.

The list of possible studies is wide and allows you to find out the state of the internal organs, vessels, cardiovascular system. And not only blood coagulability changes during menstruation.. Each of the studied parameters can be affected by bleeding for 5-7 days.

Analysis of hormones directly depends on the day of the cycle. All secrets of the glands are interconnected, so the fluctuation of sex hormones that are sensitive to ovulation and the beginning of the cycle, causes a change in other indicators. The study of the reproductive system is carried out in 1-5 critical day, that is, during menstruation.

The test for tumor markers is also performed by taking venous blood. A hormone surge can trigger a distortion of the result, especially since part of the tumors are hormone-dependent.

To understand why you can not do tests in an immune deficient state, you can learn about the features of the functioning of the protective system.

Immune cells are produced in small quantities all the time, their function is to check their own tissues for malignant degeneration and protection against incoming bacteria, viruses and protozoa. Even the slightest change in the constancy of the internal environment causes the activation of the synthesis systems of immune cells.

How menstruation is related to blood composition

During menstruation, an average woman loses 50-80 ml of blood daily. This may not have a significant impact on the volume of all this fluid, but due to the fact that the body, albeit in small doses, but constantly loses it, changes occur in almost all parameters.

There are slight losses of cells from the circulating fluid, they can begin to be intensively developed due to the immune response to a decrease in their population. Therefore, leukocytes can grow, but with a significant increase and the appearance of cold symptoms, an inflammatory process can be assumed.

If there is a true disease in the body, then the indicators may increase. Leukocytosis, as it is called the violation, appears in chronic inflammatory processes of the intestine, kidneys, digestive tract, nervous system.

Before menstruation, the hematopoietic system is activated. During the discharge, there may be a shortage of components of the blood liquid due to its loss, and at the end of the critical period the synthesis of leukocytes increases, which should contribute to the tightening of wounds on the uterine mucosa.

What period is most favorable for analyzes

Since blood tests are not recommended during menstruation, it is necessary to know which time is more suitable for this. Before critical days, changes in the state of the body begin, so most studies are recommended 7 days after their completion.

The body tries to ensure the safe passage of menstruation, so before it the hemoglobin and red blood cells are elevated. This affects blood viscosity, increases the risk of blood clots.

If you do not say about the expected beginning of the cycle, then there may be problems with blood loss and subsequent recovery of fluid volume.

For each group of indicators there is its own optimal period in which it is best to conduct research. For an immunological analysis for the determination of autoantibodies to thyroid cells, the most favorable period is 5-7 days of the cycle, that is, immediately after the end of menstruation.

PCR to determine the state of immunity is carried out on the 10-20 day of the cycle, the same period is optimal for the analysis of tumor markers. Deployed immunoassay will be true when performed 7 days after the end of the discharge.

Permitted and Prohibited Tests

Summarizing the information received, it can be said that during the monthly it is absolutely impossible to donate blood for:

  • donation
  • immunological analysis,
  • biochemical research
  • allergological analysis.

If it is not possible to postpone blood donation, then it is necessary to refrain in the first days of bleeding from research on glucose, to conduct PCR.

It is recommended to pass tests for hormones of the sexual group (luteinizing, follicle-stimulating, testosterone, prolactin and estradiol), some others (cortisol).

In the period of monthly it is necessary to make a correction for changes in the parameters of the overall analysis. The need for research can often be due to illness, and this type of analysis is the first at the diagnostic stage.

Blood donation during menstrual interruption

The cycle at normal values ​​is 28-35 days. This is the interval from the first day of some selections to the next.

A menstrual pause is a period when the body is not influenced by either the current or the next period. As a rule, it is 7-15 days after the end of the bleeding. It is during this period that there will be no effect of hormones on blood counts.

So, menstruation changes the value of almost all blood parameters. With this in mind, it is desirable to abandon the study during this period..

If this is not possible, then it is necessary to discuss with the doctor what amendments should be made to the result. It is often better to postpone the study to a more suitable day.

The relationship of donation and menstruation

It would seem that there is no connection between the physiological feature and the medical procedure. However, this view is wrong. Both processes lead to the loss of blood, which is so important for the whole organism.

Surrender during menstruation is very dangerous for a woman, because the already severe deprivation of the body of biological fluid is aggravated by an additional decrease in its amount.

Characteristics of the menstrual cycle

Such manipulations can lead not only to dizziness and poor health, but also lead to fainting. Often, syncope triggered by sudden changes in pressure: either by instantly raising it, or by instantly lowering it.

And here more about what hormones are actively produced during menstruation.

Can I donate blood or better postpone

It is strictly forbidden to donate blood during menstruation due to changes in the body, provoked by its occurrence. Coagulability disorders, just like a decrease in hemoglobin level, can lead to a particularly serious shock. If the biological material does not have normal performance, bleeding may occur.

Moreover, it is impossible not to take into account the state of a woman at this time, because there are such problems as:

  • Feeling unwell. The changed hormonal background causes fatigue, apathy and a constant desire to rest.

The loss of blood also affects the general feeling of one’s health, and the deficit caused by its additional “seizure” may even lead to a fall in syncope.

  • Pressure change. It is necessary to take into account the fact that with strong “jumps” of pressure the person’s self-perception worsens. It is prohibited to take a fence even if the donor is physically ill, a change in blood pressure is also among the contraindications.
  • Immunity problems. The suppression of the body's natural defenses caused by menstruation may result in its infection, which will increase the duration of the rehabilitation period after menstruation. Additional implementation just “finish off” the system.
  • Effect of drugs. If a woman takes pills, the action of which is aimed at anesthesia, then the active substances will certainly get into the blood, which brings them to the painful focus. It is unacceptable to donate "unclean" liquid, which contains impurities, as this may affect the health of the recipient.
  • The change in the qualitative composition of the material. Hemoglobin level decreases during menstruation. He is responsible for supplying a sufficient amount of oxygen to the tissues and organs as a whole, which is why the donation will cause severe damage to the woman, due to even greater deprivation of her needed fluid.

See this video about the benefits and harms of blood donation:

When it is allowed to be a donor during menstruation

There are situations when it is necessary to immediately help a person, especially if he is a relative or just close. However, we should not forget that a change in the level of hemoglobin in the blood can significantly degrade the quality of the biomaterial.

To bring only benefit to the needy, it is also necessary to take care that the blood does not contain various painkillers and antispasmodic drugs, which are necessary for many girls because of particularly painful menstruation. For example, 1-2 tablets of aspirin, taken to relieve unpleasant symptoms, are still allowed, but the larger amount used places a categorical ban on surrender.

Is it possible before menstruation

It also happens that blood donation for a good cause should take place a few days before menstruation. If donation cannot be postponed, then, of course, you need to go to the medical office.

However, if the procedure is planned in order to earn extra money, then the best option would be to postpone the “enrichment” for a while after the menstruation period. The fact is that before the physiological process itself the level of red blood cells rises. This process is aimed, first of all, at protecting a woman’s body from various types of infections, that is, to increase resistance to pathogenic factors.

Because of the greater than usual concentration of hemoglobin, the viscosity also increases, which is why the biomaterial intake process will be long, since the thick liquid is more difficult to fit into the syringe, and the painful action.

The optimal time for delivery will be 10-14 days of the menstrual cycle.because it is then that all the processes of the body return to normal functioning, and a noble act will bring the minimum amount of harm and unpleasant sensations.

Consequences of donating blood during menstruation

The deliberately caused blood deficiency cannot pass “with impunity”, and there are a number of consequences that a woman can expect after a biomaterial has been delivered during an already complex physiological process.

There are two options for the development of events after the procedure: either the blood released during menstruation will be in very scant amounts, or the menstruation will come with a delay.

The stress that a person experiences during fluid intake can mobilize the body, that is, put it into a state of protection. At the same time, all functions will go into conservation mode, including the production of hormones, which can lead to a malfunction of the body. If the periods turned out to be scarce, then you should not worry: the body is not ready to give even more material, therefore it tries to “save” even on such a process.

The delay provoked by the delivery of the biomaterial is also caused by the stress experienced by the body during the donation. Experiences and anxiety, too, can not pass without a trace for hormonal levels, which will cause menstruation to come later than the due date.

In any of these cases, it is necessary to ensure that such a delay does not become a symptom of more serious disorders or even pregnancy.

And here is more about whether the doctor will take a smear during menstruation.

Donation is a socially useful matter, but one should not get involved in “charity” to the detriment of one’s health. The manipulations carried out during the period of menstruation can turn into serious harm for the whole organism, therefore, a longer rehabilitation period is required, during which the woman will feel disgusting and regret making a rash decision.

Useful video

See in this video whether blood can be donated during menstruation:

Not all tests can be taken during menstruation. For example, total blood smears from the cervix will be uninformative. Ultrasound in the first 5 days is also undesirable.

On the entire menstrual cycle, these or other hormones prevail. They are responsible for ovulation, the ability to conceive, as well as common problems. What are hormones for menstruation?

Young girls are often not sure if they can go to the gynecologist during their periods. Doctors themselves recommend to postpone the visit, since the examination will be of little effect. But there are situations in which the reception in any case can not be postponed.

The amount of blood during menstruation in women of different ages is influenced by certain factors: age, weight, climate, and the presence of diseases. Will help calculate the amount of gasket.

What is the relationship between donation and menstruation

First, both processes involve the loss of blood by the body. In the case of donation, blood is taken from a vein using special equipment. The minimum amount of blood taken is 200 ml of fluid. Blood loss during the menstrual period is natural: a woman’s body loses about 60 ml of blood every day. If you add up these two indicators, you can get a very significant amount.

Secondly, blood loss during donation implies the following recuperation of the body. Female immunity and so undermined by menstrual processes, that the additional collection of blood can cause serious health complications.

The reasons for which the planned donation should be postponed.

  • The possibility of fainting and prolonged loss of consciousness. Sex hormones that control the reactions of the body during the menstrual period reduce activity, which leads to a feeling of lethargy, weakness.
  • Low hemoglobin level. It is involved in the process of delivering oxygen to the tissues of the body for vital functioning. During menstruation, the presence of hemoglobin decreases, which affects the general condition of the woman's body.
  • Reduced immunity. The reproductive system is weakened, the recovery process is slow.
  • Blood pressure values ​​due to menstruation may vary. Donation during menstruation can adversely affect the state of vascular tone.
  • Taking painkillers. Chemicals when released into the blood, adversely affect the quality of donor blood.

Taking into account the above reasons, the conclusion follows: blood donation in the days of menstruation is undesirable.

There are situations when you can donate blood during your period. It, as a biological fluid, will undergo changes in chemical composition, but will remain suitable for donor purposes.

The only condition is the absence of chemical compounds of drugs. Women can become a blood donor for menstruation in the case when it is the only way to save a person’s life.

Donor manipulations before the start of the menstrual period are undesirable. In the days before menstruation, the indicators are completely opposite to those at the time of the menstruation. Hemoglobin increases, the erythrocyte number increases.

Blood sampling during menstruation can trigger weakness and even fainting.

Medical examinations and monthly

No less interesting topic is the ability to take tests during menstruation.

Treatment of the disease involves the passage of procedures prescribed by a doctor. If at this moment you have critical days, notify your doctor about this. You can not take tests for menstruation, if you are taking medications to facilitate the process.

General rules for testing during the menstrual period:

  • The best time for testing is 5 days after the release has passed,
  • tests are done on an empty stomach,
  • urine and blood tests are done in the morning, especially hormones,
  • a couple of hours before the procedure can not be smoked.

The delivery of urine for general, daily, analysis according to Zemnitsky, Nechipurenko is extremely undesirable. The result may be a distortion of the information obtained due to the ingress of blood particles or epithelial cover. Mandatory urinalysis is required if a woman is placed on inpatient treatment or in front of an operation.

To obtain a reliable urine test result, it is important to observe all hygiene precautions. Before carrying out the procedure should be thoroughly washed, only then proceed to the collection of urine. Best for analyzing the average portion of urine. For initial urine, use a cotton swab. For collection you can buy a sterile plastic container.

There are a number of tests that allow you to check the hormones that need to be done during the menstrual cycle (given in the first days). These are tests for determining the level of such hormones as: testosterone, cortisol, estradiol and prolactin.

In conclusion, it should be noted that it is possible to take tests during the menstrual period, but the process must be connected with risks to the woman’s health. In order to avoid negative consequences, professional experts recommend not to carry out this procedure for 5-7 days after the end of the menstrual cycle.
