Welcome to icliniq.com.
I have read your query. There are two types of tests to check for pregnancy. Serum beta hCG qualitative test and beta hCG quantitative test. The qualitative test detects whether beta hCG is present or not. It can detect beta hCG more than 25mIU/ml. The quantitative test detects how much beta hCG is present. It can detect beta hCG as low as 1 mIU/ml.
Result interpretation for qualitative beta hCG test is as follows. If the result comes as positive (present), it means you are pregnant. If the result comes as negative, it means there is no pregnancy. Beta hCG is also raised in certain other conditions like ectopic pregnancy, miscarriage, molar pregnancy, and certain tumors. However, these are associated with other complaints also like a pain in the abdomen or irregular periods or bleeding, etc. Sometimes, false positive tests may occur when certain hormones are increased, such as after menopause or when taking hormone supplements. When the test is negative but pregnancy is still suspected, the test should be repeated in one week. When the test comes as positive, a person needs to go to an obstetrician and gynecologist who would evaluate the woman further. Ultrasound is also done to confirm the pregnancy.
