The HCG test is mainly used to find out whether a woman is pregnant or not. If a woman has regular menstrual periods and is pregnant on about 31-32 days after menopause, a blood test is performed and the blood HCG will show a (+) result. Clinical HCG is also used to determine the development of the embryo for the diagnosis of ectopic pregnancy and to monitor whether the pregnancy is biochemical or not. Blood HCG is very important, especially for pregnant women, while urine HCG is also used for early pregnancy, and the majority of tests are performed after 35 days of menopause if pregnancy is present (+). In addition, some medical conditions may cause elevated HCG, such as cirrhosis of the liver, so it is recommended to analyze the test in conjunction with the clinical history.
