Human chorionic gonadotropin (better known as hCG) is a hormone produced during the pregnancy period. It is made by cells formed in the placenta, which nourishes the egg after it has been fertilized and becomes attached to the uterine wall. The hCG levels can be detected using blood test from about 11 days after conception and by urine test from about 12-14 days after conception. Usually, the hCG levels will double every 72 hours. The level will reach its peak in the first 8-11 weeks of pregnancy and then will decline and level off for the remainder of the pregnancy.
Studies show that in 85% of normal pregnancies, the hCG level will double every 48 – 72 hours.
hCG levels in weeks from LMP (gestational age) are given below:
In case of a low hCG level, it must be rechecked within 48-72 hours to see how the level is changing.
A low hCG level can indicate:
In case of a high level of hCG also, it is required to recheck it within 48-72 hours to evaluate changes in the level.
A high hCG level can indicate:
The hCG levels are not checked routinely, unless you are showing signs of a potential problem. A health care provider may recheck your levels in case of bleeding, severe cramping issues, or due to history of miscarriage.
The hCG level tends to return to a non-pregnant range about 4 – 6 weeks once if a pregnancy loss has occurred.
This may differ based on the reason of loss occurred (spontaneous miscarriage, D & C procedure, abortion, natural delivery) Health care providers will continue to monitor hCG levels even after a pregnancy loss in order to ensure that they return back to <5.0.
A positive test result, may indicate that you are pregnant. Even though false positives are rare, some conditions may cause a false positive, such as certain types of cancer and early miscarriage.
Medications that contain hCG and some antibodies may also interfere with hCG levels, as well.
And it is necessary to talk with your health care provider regarding the effect of medications on test.
