Early home pregnancy tests detect the pregnancy hormone hCG human chorionic gonadotropin in your urine.
An early home pregnancy test (HPT) is designed to detect in the privacy of your own home and convenience the pregnancy hormone hCG or human chorionic gonadotropin in your urine. hCG is a hormone released by the placenta right after the embryo begins implanting into the uterine lining. You can buy home pregnancy test kits without a prescription on line at discounted prices or at a drug store . The HPT is a qualitative test, which means you do not get a certain number but just a positive or negative result.
A positive result means you have the pregnancy hormone hCG in sufficient amount in your urine and a negative test means that it's not detected.
A blood test will give you a quantitative result with a number and level of the hCG hormone in your blood. What is a "99% accurate" pregnancy?
