HCG before monthly delay

Write on what day of the cycle before the delay in menstruation, the hCG analysis showed you are pregnant.

On day 24 of the cycle (three days before the delay), hCG was equal to 77.

A week before menstruation, the result was 18.

Wow. Even a week before menstruation showed. . This I have not heard. 9 days ago I only had ovulation)))) and what cycle do you have?

Wow. Even a week before menstruation showed. . This I have not heard. 9 days ago I only had ovulation)))) and what cycle do you have?

Similarly, there was ovulation on day 9, 21 d had hCG = 159. The doctor did not believe in the consultation, the diagnosis was: suspicion of pregnancy: 004 :.

Wow. Even a week before menstruation showed. . This I have not heard. 9 days ago I only had ovulation)))) and what cycle do you have?

And how did you then insert the utrika10 days if Oh only 9 days ago was? The utr slaughters an ovulch and if the cycle is not standard and the ovulc later it is prescribed strictly after it. : 009:

And how did you then insert the utrika10 days if Oh only 9 days ago was? The utr slaughters an ovulch and if the cycle is not standard and the ovulc later it is prescribed strictly after it. : 009:

On the 14th day of the test cycle, the O showed 2 bars, which means ovul. was on 15 d.ts. From the 16th day I started to die.
Yesterday was 25 d.ts. Has handed over hCG less than 1.2. Today, the selection began, but not strong. Go to the doctor. She said so far not to cancel, and even increase the dummy to 200, 2 times a day. On Monday, pass HCG. If the same, then cancel and greed months. :( :( :(

What is HCG and when is it better to take it

Chorionic gonadotropin is produced in the normal state of the body, both in women and men. However, its concentration in the blood does not exceed 5 million units per milliliter. In the process of conception, when the DNA of the sperm and egg cells exchange genes and the formation of zygotes occurs, a number of biologically active substances are produced that trigger a cascade of embryonic development reactions.

After the fetus "sticks" to the uterine wall (this process is called implantation), in its part, which is in contact with the endometrium, the chorion, the precursor of the placenta, develops. With the help of the chorion, the embryo receives food from the mother’s blood. This formation synthesizes chorionic gonadotropin. With the development of the chorion and its conversion to the placenta, the concentration of this hormone is steadily increasing, and if it is 50 IU per milliliter during the 2nd week of pregnancy, by the end of the second month these figures will reach 60,000 IU / ml. That is why the level of hCG before the delay of menstruation makes it possible, with a high probability, to determine pregnancy at an early period.

If there is no delay in menstruation, the hgch test will help determine the pregnancy, starting approximately from the 2nd week after conception. Nominally a positive test can be from 8 to 10 days after unprotected intercourse, but in practice it is possible to speak with confidence about the reliable level of chorionic gonadotropin in the urine from 2 to 3 weeks of pregnancy. It depends on a number of factors, including the sensitivity of the test strip, the individual characteristics of the woman, the level of hormones, and so on.

Pregnancy rates

The concentration of human chorionic gonadotropin in the blood and urine is a rather individual parameter, and can vary depending on several factors. But on average, its level begins to grow from the 2nd to the 10th - 11th week of pregnancy, and then gradually decreases. If you count the level of hCG in the blood from the beginning of the last menstruation, then the change in concentration will look like this:

Q: Does the hCG test show pregnancy before a delay?

Will the analysis of chorionic gonadotropin pregnancy to delay monthly?

Currently, for the determination of pregnancy there are two options for the analysis of hCG:

1. Laboratory determination of the concentration of hCG in the blood or urine

2. Determination of the threshold concentration of hCG in the urine using the rapid test.

If to determine pregnancy before the delay of menstruation to do the usual rapid test for the determination of hCG in the urine, then most likely he will not show it. This is due to the fact that most rapid tests for determining pregnancy, available on the domestic market, have low sensitivity. These tests have a sensitivity of 25 IU / L. That is, the test will show pregnancy only if the concentration of hCG in the urine is above 25 IU / l. And such a concentration of hCG in the urine reaches only by the 3rd week of pregnancy. This means that a rapid test with a sensitivity of 25 IU / L will show pregnancy no earlier than the 5th day of the delay.

However, there are sensitive rapid tests for determining pregnancy. In such tests, the sensitivity to hCG is 10 IU / l. That is why these sensitive tests will show pregnancy when the level of hCG in the urine reaches 10 IU / l. Usually the level of hCG in the urine of 10 IU / l is observed by the end of the first week of pregnancy. This means that this test will show a pregnancy 7 days after unprotected intercourse. Doctors and scientists believe that a sensitive rapid test can be done 2 - 3 days before the planned menstruation, and he can already show a pregnancy, if one has come.

If, however, for the determination of a pregnancy before a delay, blood is given for the analysis of hCG, then it can either show it or not, depending on how much time has passed since the moment of conception. A blood test for hCG will show a pregnancy if 6 to 10 days have passed from the moment of conception (unprotected intercourse). Accordingly, if at least 7 days have passed from the moment of conception, and the term of the proposed menstruation has not yet arrived, then a blood test for hCG will show pregnancy. Doctors and scientists recommend taking a blood test for hCG to accurately determine the pregnancy before the delay, at least 7 days after the alleged conception. The optimal time for taking a blood test for hCG, when it shows a pregnancy even before a monthly delay, is 10 days after the expected conception date.

When hCG rises

Any test considers its task to detect urine concentrations of hCG (a special pregnancy hormone). But it is contained in any body fluid, incl. and in the blood. To pass it on HCG before the delay of menstruation is necessary on the 10-11th day after fertilization, and then to confirm the result, repeat after 5-7 days.

Tests are done no earlier than 15 days after conception or on the first day of the absence of critical days. If there is a delay in menstruation, and hCG is negative, the day of cell release is most likely incorrectly set.

Features result evaluation

Accordingly, she immediately runs to the pharmacy for the saving strip and after the research she receives one control line. In addition, changes in the cycle can affect:

  • polycystic ovary syndrome,
  • lactation,
  • recent childbirth
  • stressful situation.

Possible problems

The rate of choreonic gonadotropin in the blood of a non-pregnant woman is from 0 to 5 mIU / ml. When during the delay of monthly hCG 1 mIU / ml, it indicates possible problems:

  • incorrectly determined period of pregnancy (conception occurred later than estimated),
  • ectopic pregnancy,
  • missed abortion
  • risk of miscarriage.

With a delay in monthly HCG, the indicator with a negative result may indicate changes in the cycle at the moment, doctors recommend repeating the test at least 5 days later.

To get a guaranteed-correct result, testing should be carried out a week after the date of the failed critical days. For particularly impatient, it is recommended to conduct an hCG test before a monthly delay. It will show pregnancy, perhaps, 5 days before the expected date of blood discharge. But in this case it is worth using hypersensitive jet tests.

Can. This is one of the earliest ways to determine.

Sure you may! If there is something the analysis will be positive

Yes, before the delay, the analysis of the hgch immediately gives a reliable result. I wish you this result to be positive! Good luck!

Thanks for answers!
I called in two different laboratories, in one they said that it was possible with my term, and in the second - no :-)
P.S. I have today 22 days from the first day of the settlement, usually monthly periods come to 28-30 days.

Thank you, I'll give it if that several times.
And the signs do not go through nausea abruptly and for no reason, the back looms and the chest is sensitive. And if to consider that unprotected sex was once exactly on day 14 (the husband today returns from their business trip :-), I will hope for the best.
THANKS FOR THE SUPPORT!

A guest,
I have no mania, since there is already a child, my husband and I decided to have a second one and the first month was not protected. And these signs immediately appeared, although usually the onset of menstruation I DO NOT FEEL AT ALL, and my chest is never non-lethal, and even less nauseous - there is never, the first pregnancy passed without any toxicosis at all.
So your assumption (for mania) is not true.

In fact, the analysis of hCG shows pregnancy, if it takes place, after about a week - 10 days after the intended fertilization. So consider yourself. And about mania. you know, I also have 3 cycles in a row and my stomach was aching and nauseous. and monthly came on time. may be hormonal failure. because of the heat, for example. But if you want a baby, then I wish you the cherished //. )))

Show At the same time, hand over to progesterone - make sure that its level is sufficient to save the pregnancy And what, at the beginning of the pregnancy is sick? This usually happens a few weeks later.

On Monday when I receive the analysis I will unsubscribe.
Thank you all for the information and support!

You have only 22 dts .. Ovulation was at 14 perhaps. It takes place at 26-27 dts, not before

I agree with 10, give hCG and progesterone at the same time. By the way, progesterone also changes during pregnancy.
I handed over to Invitro both. If you donate several at once, save on paying for blood.
Good luck!

nauseous can not you yet. most likely ate something wrong.

Hello girls!
My question is: is it possible that a blood test for a bhcc is false? I have every reason to believe that I am pregnant: nausea, drowsiness, high nipple sensitivity, a couple of times the pace. body to 37 rose. Until menstruation about 2-3 days. The analysis showed

Blood test for hCG: rules for delivery

If a woman has decided to pass a laboratory analysis to determine the concentration of human chorionic gonadotropin, then she, of course, should know how to do this as correctly and efficiently as possible.

Blood for hCG is collected from a vein. The analysis should come in the morning of the day when it is scheduled for delivery. It is forbidden to eat until the moment of blood taking. Testing under laboratory conditions is recommended to be done not earlier than the fourth or fifth day from the delay of menstruation. To confirm the results, the test can be performed again after a couple of days have passed. In order to establish the pathological prenatal development, it is recommended that the analysis be carried out starting at 14 weeks. pregnancy and up to 18 weeks.

In the case of complex diagnostics, it is shown that tests are performed to identify such markers as alpha-fetoprotein, free estriol, and ultrasound of the fetus.

Features of a specific component of pregnancy

Complex protein hCG (human chorionic gonadotropin), CG - has a molecular weight of 46 kDa, synthesized by the placenta. The composition of CG includes two subunits - alpha with beta. The first subunit is similar to those of the pituitary hormones FSH, TSH, and LH. The second subunit, which is involved in immunometric analysis, has no analogues.

The amount of blood beta-hCG already by 6-7 days after fertilization of the egg is taken as the criterion for diagnosing pregnancy. At the same time, the determined concentration of beta-CG in the urine accumulates for a day or two later than in the blood serum.

At the very beginning of the birth of a new life in the maternal organism, chorionic gonadotropin stimulates the synthesis of progesterone and estrogen (necessary for the preservation of pregnancy) by the corpus luteum of the ovary. Действие ХГ на желтое тело сродни лютеинизирующему гормону: поддержка существования. Что длится до того момента, пока симбиоз «плацента-плод» не выработает способность самостоятельного создания требуемого баланса гормонов.

In the fetal boy, CG is responsible for the production of testosterone producing Leydig cells. The latter is a male hormone responsible for the formation of sexual characteristics in men.

HCG is synthesized in the trophoblast when the embryo is implanted. Its production accounts for the entire duration of pregnancy. When the pregnancy is not complicated, then in the interval between the second and fifth weeks the number of beta-CG increases every one and a half days. The summit of CG growth corresponds to 10-11 weeks, then its volumes begin a gradual movement in the opposite direction.

Identification of the amount of CG for 15-20 weeks. (in combination with other studies - for free estriol and alpha-fetoprotein, referred to as "triple testing") is used in perinatology to detect possible pathology in the development of the embryo.

The use of hCG is not limited only to detect pregnancy. In addition, they are diagnosed with tumors of trophoblastic tissue, ovaries and testes that produce chorionic gonadotropin.

Indications for CG analysis

Chorionic gonadotropin, in addition to the definition of pregnancy (in the first days before the delay), is prescribed:

  • to detect amenorrhea,
  • to clarify the situation with an ectopic pregnancy,
  • in analyzing the quality of the abortion,
  • if you suspect a frozen fetus and the threat of miscarriage,
  • to monitor the progress of pregnancy in the dynamics,
  • in order to diagnose the tumor process,
  • to establish the fact of intrauterine malformations.

The purpose of the glycoprotein CG in the body

In addition to establishing the fact of pregnancy, to determine the amount of this hormone is judged on the peculiarities of the course of pregnancy, the number of embryos. But more important is considered another function of the hormone - maintaining an existing pregnancy. Another equally important role of chorionic gonadotropin is to stimulate ovulation and maintain the activity of the corpus luteum.

The increasing concentration of human chorionic gonadotropin can be regarded as a sign:

  • the presence of several fruits
  • preeclampsia, toxicosis,
  • diabetes mellitus in the future mother,
  • Down syndrome, multiple developmental abnormalities, fetal abnormalities,
  • improper establishment of pregnancy,
  • use of synthetic gestagens, etc.

Even higher values ​​are when passing the analysis after surgery for abortion. Excessive concentration of complex protein in the blood after a mini abortion can confirm a continuing pregnancy.

Chorionic gonadotropin is recognized as an informative criterion for pregnancy, an indicator of its course and possible deviations.

all signs, and hCG until delay is small

Good morning, please tell me what it can be, bz the temperature she had for 37 weeks the last three days 37.2 months should go today for a week pulling the ovaries from different sides, her chest literally poured out for three days and it hurts, although before the month it hurts for a week. The tests of 5 pieces show a pale, pale second husband. My husband also sees a second pale one, but yesterday I passed a hgch. He didn’t have a pregnancy 0.1. I don’t have to read after three four days of delay, I don’t know what it is then ?? if not pregnancy? can still pregnant? I read what else could be ectopic and therefore slowly grow hgch? Tell me, I'm worried

Why it is better not to do a test before the delay (answer)

I did the test, there was still no delay, and the test showed the 2nd strip instantly! But just in case (knowing that the tests "can lie" can) the next day, she passed the hCG (the pregnancy was confirmed). It seems to me that it is better, if there is a suspicion of pregnancy, to always donate blood on hCG, so that you know for sure and not worry.

Thanks you! Good article

Very useful information with interest and calculations, that is what I was looking for for a long time! Thank you, very encouraging

Early diagnosis of pregnancy - analysis for hCG

Girls, hello everyone.

Help please understand, maybe someone knows.

in general, my last periods were in February, usually they start on the 28th of each month and go 5 days in total.

It is already April, I do not have them. We live with the future husband of family, sex life, we do not protect ourselves, we want kids, both he and I.

did tests, did not show anything, went to the ultrasound on 21.04, the doctor said that she did not see the pregnancy, but sent me to donate blood to HCG. I went to donate, I got the result 2 days later, the girls said both by phone and in person when she picked up the paper , they said that a positive result of the hCG level means that she is pregnant ... the indicator is 19.89 (16-156 written in the notes (1-2 weeks), and the gynecologist said at the ultrasound that if the time limit is small, then it will not show ultrasound

I went to the gynecologist because I started to turn me: I felt nauseous (I even ran to vomit), it hurts and continues to hurt my chest and itch terribly until now. It hurts so much that it is painful to wear a bra.

we were already delighted, I still wanted to go to the ultrasound in another week and re-donate blood.

but tonight it became bad, woke up from pain in the lower abdomen, gave in the back.

I went to the toilet, there was a bloody discharge. I woke my husband up naturally, called an ambulance ... I drank some alcohol. I came and took it, I was taken to the hospital on duty.

there they took blood from a vein (for leukocytes and so on), were taken to the examination room, to which the doctor said: hahah, so these are not indicators! it means you are not pregnant. if you had the last menstruation in February, now you would have already 10-11 weeks, and at that time the fetus is already visible on the ultrasound. In general, it was sweet, As I could, it looked like it looked, said that there is nothing, no pregnancy, and that they say they see some kind of growth or deposits, but this is most likely your menstrual period ... they supposedly dripped, dripped and deposits formed ... in general, I flew out with tears ... was hysterical ... like that fast at night.

and she also said that they say: ordinary girls from the street work in the laboratory and they say they do not understand this, as it is written on paper, then they say.

the stomach continues to hurt.

By the way, the day before I did the test, showed the second strip-pale.

tell me ... I do not know what to do.

Naturally, tomorrow I will go to the doctor.

hi all, I generally think about these modern analyzes of chipuha pregnant means pregnant and then if so then so and so then syak, there was no ultrasound before and gynecologists immediately found and set the exact date and now everything is there, but like in Chinese on snot, even on Nichrome ultrasounds do not see the deadlines, all are not accurate, but the hgch is generally nonsense for water tests are even more accurate and more expensive, one friend passed the hgch and there is nothing empty, a day later the inkjet test turned out to be positive and after two weeks 6-7 weeks pregnancy on the ultrasound revealed although two weeks n Azad, too, did not see anything here, as it happens, and then gynecologists say if, during pregnancy, Khan bled, yeah, they lie or underinsure, but my mom, as if full of things, had monthly periods and was stronger than usual, and I was born in time obsalyutno healthy with good weight to the article, the mother was also healthy and gained weight, if the girls fate will become pregnant and the pregnancy will not disappear for a long time sometimes it happens for the best my mother didn’t go to the doctors with me because she’s like a boy on the armchair that light about they were already in the long run, but they are forcing the account to get up because of the military who warned them that they are conducting experiments and there may be problems for the potam how much you don’t stand on the records anyway how the chip will fall and infertility is also a sign of passing experiments, wait for longer if there is no pain in the anus and off the hook, and then only testik and as budud 2 strips and go to the ultrasound and hgch shit, and even expensive shit.
