Human Chorionic Gonadotropin (hCG) in Serum/Plasma

Why Is This Test Done?

Your healthcare provider may order an hCG test to confirm pregnancy, especially if you have missed your period or suspect you might be pregnant. It can also be used to monitor early pregnancy, check for complications like miscarriage or ectopic pregnancy, or evaluate certain medical conditions in non-pregnant individuals, such as ovarian tumors or other hormonal imbalances.

What Does an hCG Test Involve?

A blood sample is taken from a vein in your arm. You may feel a small pinch when the needle is inserted, but it usually doesn’t cause significant discomfort. The sample is then sent to a lab for analysis.

What to Expect Before or After the Test

There are no special preparations needed for this test. If you are pregnant, you may want to avoid smoking or consuming alcohol before the test, as these can sometimes affect results. After the blood draw, you can resume your normal activities immediately.

What Are Common Results and Their Meanings?

hCG levels vary depending on the stage of pregnancy. Very low or undetectable levels may suggest early pregnancy loss, missed period, or non-pregnancy. Elevated levels beyond expected ranges could indicate complications like ectopic pregnancy or certain non-pregnancy-related conditions. Your healthcare provider will interpret the results in the context of your medical history and symptoms.
