Free Beta HCG (Human Chorionic Gonadotropin) is produced by the placenta during

pregnancy. This test is used to confirm pregnancy, detecting ectopic pregnancy, potential

miscarriage and screening of downs syndrome. High levels of beta HCG may also indicate a

specific type of ovarian cancer in women and testicular cancer in men. Beta HCG is normally

present in low amounts in men and women, the level of beta HCG increase during the initial

period of pregnancy and falls to negligible levels after delivery. This test is also used to

evaluate treatment with certain anticancer drugs and the patient’s response to the treatment

and its effectiveness.
