What is hcg TOTAL in blood tst?

Human chorionic gonadotropin (hCG) is a hormone produced by the placenta during pregnancy. hCG levels rise rapidly in early pregnancy, reaching a peak at around 10-12 weeks. They then decline gradually until delivery.

A blood test for hCG can be used to diagnose pregnancy, estimate the gestational age of the fetus, and monitor the progress of a pregnancy. hCG levels can also be used to detect certain medical conditions, such as ectopic pregnancy, miscarriage, and gestational trophoblastic disease.

hCG TOTAL refers to the total amount of hCG in the blood, including both the intact hormone and its beta subunit. The beta subunit of hCG is the most commonly measured form of hCG in blood tests.

Normal hCG levels vary depending on the stage of pregnancy. Here are some general ranges:

* Non-pregnant women: Less than 5 mIU/mL

* Early pregnancy (4-6 weeks): 5-50 mIU/mL

* Mid-pregnancy (7-12 weeks): 100-500 mIU/mL

* Late pregnancy (13-40 weeks): 1,000-50,000 mIU/mL

hCG levels can also be used to calculate the gestational age of the fetus. This is done by comparing the hCG level to a standard curve. The gestational age is then estimated based on the hCG level.

hCG levels can also be used to monitor the progress of a pregnancy. For example, a sudden drop in hCG levels may indicate a miscarriage or an ectopic pregnancy. Rising hCG levels may indicate a healthy pregnancy.

**However, it's important to note that hCG levels can vary from person to person and that a single hCG level is not always enough to make a diagnosis. Therefore, results in blood testes should always be interpreted by a qualified healthcare professional.
