Pregnancy test
Normal Values
HCG levels rise rapidly during the first trimester of pregnancy and then slightly decline.
What do Abnormal Results Mean?
HCG levels should double every 48 hours in the beginning of a pregnancy. HCG levels that do not rise appropriately may indicate a problem with your pregnancy. Some problems associated with an abnormally rising HCG level include miscarriage and ectopic (tubal) pregnancy.
Extremely high levels of HCG may suggest a molar pregnancy or more than one fetus -- for example, twins. Your health care provider will understand the significance of your HCG levels, and he or she should discuss the levels with you.
