hCG Blood Test – a necessary examination to determine pregnancy and its duration based on the level of a specific hormone, human chorionic gonadotropin.
General Information
hCG is a hormone produced by the embryo from the moment it attaches to the uterine wall. Typically, its levels begin rising as early as the fourth day after presumed conception.
An elevated hormone level confirms successful conception. However, in non-pregnant individuals, it may suggest suspicion of cancers such as breast, stomach, or ovarian cancer.
Procedure Process
During the first trimester, human chorionic gonadotropin regulates the production of progesterone, estriol, and estradiol, which ensure normal fetal development. Its peak occurs at 8-9 weeks, after which other biologically active substances produced by the placenta take over.
If you’ve wondered how the second line appears on a pregnancy test, the answer is simple: it’s the body’s reaction to hCG levels in urine.
Hormone levels rise in the earliest days post-fertilization, and in some women, by day 8 or 11. Thus, if the exact conception date is unknown, it’s recommended to test for hCG at 3-4 weeks from the estimated start of the last menstrual period. Sometimes, doctors order two tests a few days apart for greater accuracy. A roughly twofold increase indicates conception.
Note: Repeat tests should be done at the same lab, as norms may vary, and measurements may use different units.
In non-pregnant individuals, hCG levels range from 0-5 mIU/mL. In pregnant women, it varies by gestation week, gradually declining after the first trimester (counted from the start of the last menstrual cycle).
Indications
The hCG blood test is indicated for:
- Confirming pregnancy;
- Detecting fetal developmental anomalies;
- Assessing miscarriage risk;
- Identifying potential cancers.
Contraindications
No contraindications have been identified for this test.
The hCG test, part of the triple test, cannot diagnose pathology with 100% certainty, so it should not be the sole basis for conclusions. It identifies risk groups and prompts further, more detailed examination.
The key informative aspect is not the absolute hormone level at a given moment but the dynamics of its changes.
