How do Pregnancy Tests (HCG) work?
Pregnancy tests are to detect the presence of human chorionic gonadotropin ("HCG"), which appears in urine very early in pregnancy. Regardless of the technical language, this test works just like most other pregnancy tests out there. It measures the levels of the pregnancy hormone human chorionic gonadotropin (hCG) in your urine. This hormone is produced by the cells of the embryo that will later form the placenta. The level of hCG starts to increase from its basal level of less than 5 mIU/mL directly after implantation, and doubles about each 48 hours during the first weeks of pregnancy.
How do Ovulation Tests (LH) work?
The LH (Luteinizing Hormone) which is in the urine of normal women will increase dramatically in the middle of the menstrual cycle. The LH increase triggers ovulation which is when the egg is released periodically from Normal fertile women. WHO experts state that LH testing is a reliable way to detect ovulation. Ovulation will occur after 24-48 hours following a positive test. One Step Ovulation Urine Test is a qualitative test used to predict when there is a LH surge, and in turn, when you are likely to ovulate.
