Pregnancy test strip, 10 pcs

During pregnancy, the mother excretes increasing amounts of chorionic gonadotrophin hormone (hCG) into urine. By the first date of expected but missing menses, hCG level in urine exceeds 25 mIU/ml and doubles every second day thereafter. The sensitivity of standard pregnancy tests is adjusted to 25 mIU/ml to ensure that the reason for missing menses is pregnancy.
