Novamed One Step Pregnancy HCG Test Kit is intended for non-professional use by qualitative identification Of Human Chorionic Gonadotropin (Hcg) in urine to aid the determination of pregnancy. You can carry out most pregnancy tests from the first day of a missed period. The morning urine tends to be the best time to take home pregnancy tests, because hCG levels in urine are concentrated. At-home Preganancy tests require higher levels of hCG to detect a pregnancy, typically at least 20 mIU/mL. Each day of early pregnancy, your body will create more hCG. As the weeks go on, you'll have more and more hCG in your body, which will make it more likely that a pregnancy test will show as positive. Pregnancy tests work by reacting to the amount of hCG in either your urine or blood. Each individual pack of Novamed Home Pregnancy Test Kit contains 1 test kit, dropper and instructions manual.
