VIDEO: Decoding of HCG analysis

Almost every woman is trembling with regard to motherhood, so at the first signs of pregnancy, she tries to confirm or deny her assumptions as soon as possible.

Where to donate HCG?

Unfortunately, not all district clinics have appropriate equipment for determining the concentration of this hormone in the blood. But paid laboratories and clinics will conduct your blood tests without problems, in order to find out the concentration of hCG.Analyzes without a queue are paid for free, but there are also free referrals that the doctor issues. In this case, blood donation will be possible only on the appointed day and time.

When can I donate blood to HCG, on which day before the delay and after a delay in menstruation?

Modern equipment can capture the growth of hCG as early as 8-9 days after intercourse. That is, from the moment when the fetal egg is attached to the walls of the uterus. In urine, this hormone is fixed much later, about 2 days after the delay of menstruation. In the blood, 100% of this hormone can be detected during pregnancy from the first day of the menstrual period.

Blood on HCG - how to properly give: on an empty stomach or not, can I drink water before testing?

This study will give a 100% accurate result in case of proper preparation. Doctors recommend taking blood from a vein exclusively on an empty stomach, that is, without eating food in the morning. In addition, the most accurate for taking blood is the time from 8 to 10 am. This is due to the fact that after sleep the amount of hCG in the blood is maximal. You can drink water early in the morning and even in the queue for hormone replacement. It does not affect the results in any way.

After how many days after conception, at what time will the blood on the hCG show pregnancy?

It all depends on the accuracy and sensitivity of the equipment. Usually a positive result can be obtained within a week after conception. But to be 100% sure of the accuracy of the result, wait for the delay in menstruation.

How much is the blood test for HCG prepared, after how long to wait for the result?

In general, from the beginning of the analysis to the delivery of the results, it takes approximately 3-4 hours. At the same time, it is sometimes necessary to take 15 samples for a full load of the device. Then the patient is forced to wait until the specified number of blood samples is collected. Usually in express laboratories where there are many patients, the results are given out the next day.

Some laboratories do not have their own staff and are only intermediaries. In this case, the samples are taken to the equipped laboratory. Then the analysis will take several days.

Do I have to take blood on HCG and on what date?

At the very beginning of pregnancy, there is no need to take biomaterial for this hormone, since it will be known about the fact of pregnancy without this research a little later.

Required delivery of blood for HCG:

First trimester. Tentatively conducted from 11 to 14 weeks. It is carried out not as an independent analysis, but in conjunction with other blood tests. The test is called biochemical screening. During the analysis, the concentration of hCG and plasma protein is determined. According to the data obtained, it is possible to judge a multiple pregnancy or the presence of pathologies in the fetus.
Second trimester. This analysis is called a triple test, as the concentration of three hormones is measured. It is held at 16-18 weeks. During the test, the ratio of AFP, free estriol and hCG is determined. This test helps identify congenital malformations in the fetus and, if necessary, make medical abortion.

Is it possible to give blood on hCG in the afternoon or evening?

No, it's impossible to take the biomaterial for analysis at lunch and even more so in the evening, as this will significantly affect the results. In the evening, the concentration of hCG can decrease several times. Therefore, if you receive an unreliable or doubtful result, you will be forced to retake the blood again.

Where does the blood take HCG: from a vein or a finger?

Only venous fluid is used for testing. That is, the selection of the biomaterial is carried out from the vein.

The level of hCG in the blood during pregnancy: transcript, table by day and week of pregnancy

An approximate table of the concentration of the hormone in the blood at different periods of pregnancy is given in the table. It is worth considering that the data have a significant run-up, since the concentration of the hormone in each woman is different.

Analysis of hCG: pregnancy rate

Each pregnancy has its own rate of hCG.With increasing pregnancy, the concentration of this substance is constantly increasing. It is the increase in concentration and is a sign of a developing pregnancy. The maximum value of this hormone reaches 10-11 weeks of pregnancy. After that, the growth of the hormone ceases and is at a constant level until the very birth.

What affects the level of hCG in the blood?

The level of this hormone affects the mass of internal and external factors. Try to donate blood in the same laboratory all the time, as the data between the laboratories can differ significantly.

Factors affecting the content of hCG in the blood:

Pregnancy of twins or triplets
Ectopic pregnancy
Presence of maladies and malformations of the baby
Early toxicosis
Diabetes mellitus
Pregnancy stopped
Incorrect pregnancy term set
Accepting hormonal preparations
Taking blood after eating

When is hCG in the blood?

The increase of this hormone is observed immediately after the attachment of the fetal egg in the uterine cavity. Normally, the concentration increases twice a day. But there are cases when the number of times exceeds the permissible standards. This indicates a multiple pregnancy and an incorrect timing. In addition, increasing the value can talk about chromosome ailments of the fetus.

The level of hCG in the blood after miscarriage

As mentioned above, the maximum amount of the hormone is observed at 11-13 weeks of pregnancy with a gradual decrease and fixation at 16 weeks. After miscarriage, for several days the concentration of hCG will gradually increase. Only 4-7 weeks after the termination of pregnancy, the concentration will become standard, that is, not as in a pregnant woman.

HCG level in the blood of non-pregnant

. Not pregnant women ideally in the blood should not have hCG.This hormone is produced directly by the chorion of the embryo. If the woman is not pregnant, then the concentration of the hormone is 0-5 units. If the number is higher and there is no pregnancy, this may indicate a cancer of the liver or kidney. Some malignant tumors produce this hormone.

Can a blood test for hCG show ectopic pregnancy and what level of hCG in the blood in an ectopic pregnancy?

To determine ectopic pregnancy with hCG can be in dynamics, that is, with constant comparison. With ectopic pregnancy, the importance of hCG is much lower and does not increase so rapidly. Sometimes there are jumps, but the level of hCG almost does not increase.

Can a blood test for hCG be mistaken?

In fact, this analysis is very sensitive. This is both a plus and a minus. The fact is that even in the early stages even before the delay, you can learn about pregnancy. But in this case, any violations of the rules for the delivery of blood strongly affect the results. Therefore, to confirm bad tests, you will have to re-take blood several times.

And no doctor will undertake to talk about drug abortion, based only on the analysis of hCG.Only after ultrasound with the measurement of the thickness of the nose and the collar zone of the child can you judge the syndrome of Down.

As you can see, hCG is a hormone that allows you to determine pregnancy at an early stage, as well as diagnose possible pathologies in the fetus. Always follow your doctor's recommendations and go through all the exams.
