A blood test for hCG, or human chorionic gonadotropin hormone, is one of the most dependable methods for confirming a pregnancy, which is something that many soon-to-be parents look forward to. When seeking an accurate result, healthcare providers frequently recommend this test because it can detect pregnancy earlier than home pregnancy tests.
Pregnancy causes the production of the hormone hCG, which is higher in the early weeks as the body provides support to the growing embryo. Whether you’re tracking a pregnancy or planning a baby, knowing when and how to take this test can help ensure the most accurate results.
This post will give you advice on when to give blood for hCG, describe the procedure, and offer helpful hints for getting ready for the test to guarantee the best result.

What is it?
The female body produces a large number of new hormones during pregnancy that it was not used to. Chorionic gonadotropin is one of these physiologically active compounds. It’s called hCG for short. Though it is essentially unknown, it is typically present in a healthy body. This biologically active material is found in much higher concentrations following an abortion, during pregnancy, and during the development of some malignant neoplasms.
When a woman’s hCG test comes back positive, she can finally get rid of her doubts about her pregnancy. This hormone gradually rises in levels. However, this indicator starts to rise in the early stages of fetal development.
Researchers have discovered that the hCG hormone can exist in various forms. We refer to them as beta and alpha fractions. These substances have distinct structures. The hormonal effect of the beta fraction is more noticeable. Pregnancy also causes an increase in its values.
The functions of HCG in a pregnant woman’s body are numerous. If the expectant mother is carrying a boy, it contributes to raising testosterone levels and balancing the hormonal background. This biologically active ingredient is also essential for priming a pregnant woman’s immune system for childbirth.
Antibodies are not formed in the expectant mother’s body as a result of the increase in hCG in her blood, which can result in the fetus being rejected.
HCG also plays a role in the proper placenta formation as the pregnancy goes on. Only during pregnancy does the female body produce this unique formation. Numerous blood vessels traverse the placenta, guaranteeing a continuous flow of blood to the fetus’s essential organs.
How to take the test correctly?
For a laboratory test of this kind, preparation is crucial to getting a trustworthy result. During a visit to the gynecologist, a pregnant woman receives all the necessary advice on how to properly prepare for this laboratory test.
It is essential that you take the test without eating. The blood hormone levels will be more precise in this situation. Eight hours before the test, in the evening, is when you should have your last meal. It is best to prepare dinner as light as possible in this situation. Foods that are fried or high in fat should be avoided the night before the study.
Each laboratory may have its own set of guidelines for administering tests. There are, nevertheless, a few particular general guidelines for carrying out this investigation. A woman or girl should not rush to the lab to donate blood for this hormone if she has any doubts about being pregnant.
Its blood level is extremely low in the initial days following conception, making it impossible to determine whether a pregnancy is there.
Usually, on the fourth or fifth day following a menstrual delay, doctors advise visiting the lab to measure this hormone. There are certain clinical circumstances in which pregnancy cannot yet be determined. In the event that the menstrual delay surpasses a week, a control study becomes necessary. Seven days following the first day of the anticipated day of the onset of menstruation, it can be repeated.
Venous blood is used in the study. A pregnant woman is required to disclose to her gynecologist any medications she is taking. The amount of this material in the blood can be indirectly impacted by certain medications. Immunosuppressive medications and a variety of hormone medications can have particularly negative effects.
Blood donation for testing is advised by doctors 14–20 days after ovulation. During pregnancy, hCG levels already rise noticeably at this point. Water is okay to consume prior to this test. The resulting test needs to be rechecked if the analysis produced dubious results. To obtain a more trustworthy result in this instance, it is preferable to carry out the investigation in a different lab.
It should be mentioned that one can ascertain this hormone’s content at home. Different test strips are used for this, and they are available at any pharmacy or even a typical supermarket. There is no 100% pregnancy indication in this analysis; it is merely approximative. In order to make a diagnosis, this hormone needs to be measured in venous blood.
In what cases is it performed?
The measurement of hCG is done for purposes other than confirming a woman’s pregnancy. The identification of oligohydramnios, multiple pregnancies, and other conditions is also greatly aided by this study.
An analysis to identify this hormone is typically carried out at 8–12 weeks of pregnancy, and again at 16–20 weeks to screen for different pathologies. Individual prescriptions for these studies are made, taking into consideration the clinical circumstances, the fetus’s health, and the pregnant woman’s well-being.
A woman who is not pregnant experiences an increase in hCG in her body, which is always a sign of a specific pathology. Testicular cancer in men is not immune to the manifestation of this pathological condition. Elevations of chorionic gonadotropin in the blood are also linked to certain genital organ oncological diseases.
In this instance, determining which specific oncomarkers to determine is mandatory in order to establish the correct diagnosis. Using magnetic resonance imaging or computerized imaging will assist in determining the primary location of the expanding tumor.
Following an abortion, a woman’s blood still contains a comparatively high amount of this hormone. It takes a few days for it to start declining. In this instance, tracking the dynamics of hCG reduction is necessary and mandatory. This is what should be done following an abortion for a week.
The high concentration of this hormone in the blood has persisted over time, which could mean that some tiny fragments of the fetal egg are still inside the uterus. To get rid of them in this situation, an emergency gynecological procedure is needed.
Both men and women who use anabolic steroids have higher chorionic gonadotropin concentrations. Researchers have long known that prolonged use of anabolic steroids can cause infertility and chronic diseases of the genital organs. In this instance, there is a noticeable increase in hCG levels in the blood for a considerable amount of time.
