Diagnostic evaluation of human chorionic gonadotrophin hormone in pregnancy urine.

Human chorionic gonadotrophin (HCG) is characterised primarily by luteinizing and luteotrophic activity. The presence of a certain amount of HCG in urine of women is the basis for a number of pregnancy tests and its content is diagnostic in evaluation of foeto-placental health during pregnancy, indicative of safe normal pregnancy, multiple pregnancies, threatened abortions and many other trophoblastic diseases such as hydatidiform mole and ectopic pregnancy. In this investigation attempts have been made to evaluate HCG in full term gestation, to determine the fiducial limits in order to avoid individual error of excretion of HCG and subsequently to correlate the levels with various disorders occurring during abnormal pregnancy.
