HCG beta test to confirm pregnancy - pregnancy test, blood test and norms


Beta HCG is a hormone that a woman's body mainly produces during pregnancy. Primary task beta chorionic gonadotropin is controlling its proper course and regulating fetal development. The proper level of HCG beta hormone in pregnancy andhe generally informs that pregnancy develops correctly. The HCG hormone can be detected both in the urine and in the blood of the future mother. The latter option, however, is more accurate and with ultrasound examination is the surest confirmation of pregnancy.

HCG beta test using a pregnancy test - when is it worth doing?

The beta hormone HCG is detectable in a woman expecting a baby already on early stage of pregnancy. However, it is worth being aware that it makes no sense to do a pregnancy test before the expected date of menstruation, because the level of beta HCG may still be too low for the test result to be fully reliable. That's why all women who are trying to get a baby they should wait with the test at least until the day of the expected menstruation. If it doesn't appear then it's worth it take a pregnancy testto confirm or exclude pregnancy. Modern pregnancy tests are so sensitive that they can correctly detect the presence of chorionic gonadotropin hormone in the urine already two weeks after conception.

Beta HCG blood test - the most effective method of confirming pregnancy

If the pregnancy test is positive, the next stage of pregnancy confirmation is blood test. This is because the most effective method indicating the presence of a developing embryo in a woman's body. However, it is best to do such a test after a positive pregnancy test in order to finally confirm pregnancy. It is worth to decide on them also in the case when the test result is negative, but menstruation did not occur, and we have a strong feeling that we are pregnant. A blood test is not necessary, however, to confirm pregnancy it is often enough to visit a gynecologist.

Increased beta HCG levels in pregnant women are detectable just a few days after conception, and his presence in the blood in a properly developing pregnancy is growing every day. It is assumed that pregnancy is confirmed by beta HCG levels above 5 mlU / ml. Lower values, in turn, should be interpreted in two ways: either they indicate the absence of pregnancy, or the test was performed too early. In the latter case, it is worth repeating them after about a week.

A beta HCG test can be done without a referral. To do this, just go to the clinic and give a blood sample to detect the presence of chorionic gonadotropin. The test is carried out for a fee, but its cost is small and oscillates around 30 PLN.

Beta HCG norms in the first weeks of pregnancy

Detecting the presence of the HCG beta hormone in pregnancy is not enough, however, to be able to start preparing for the birth of our child. The task of the beta HCG test is not only to confirm pregnancy, but also to accurately indicate the level of chorionic gonadotropin hormone in the blood of a woman. Systematic growth is necessary for the proper development of pregnancy. The principle is that in the first weeks of pregnancy, its level should double every 48-72 hours. This regularity testifies to the proper development of the embryo and the progress of pregnancy.

It is assumed that the normal beta HCG values ​​in pregnancy are (counting the weeks since the last menstrual period):
Week 3: 5 - 50 mIU / ml
Week 4: 5 - 426 mIU / ml
Week 5: 18 - 7 340 mIU / ml
Week 6: 1,080 - 56,500 mIU / ml
7th - 8th week: 7,650 - 229,000 mIU / ml

In the event that we decide to do the HCG beta test on our own and the pregnancy is confirmed by us, it is worthwhile to go with the results of the examination to a gynecologist who will assess the correct level of HCG beta and take appropriate steps in the event of any deviations from the norm.

Too low HCG beta level - what can it mean?

Too low a level of chorionic gonadotropin hormone in a woman's blood may most often indicate ectopic pregnancy or miscarriage. That is why it is so important to consult the results of a blood test with a doctor who will be able to take the right steps if abnormalities in the development of pregnancy are detected.

If an ectopic pregnancy is suspected, it is performed additionally ultrasound examination, which allows to detect the location of the embryo. However, if the HCG beta level is found to be too low, the gynecologist also orders a re-examination after a few days to see if its level is rising. If this is the case, in most cases it means that the pregnancy is developing properly.
