Content: But how accurate are home pregnancy tests, and what external factors can affect the results? Here's everything you need to know. How Accurate are Pregnancy Tests? Home pregnancy tests claim to be about 99 percent accurate. Indeed, with proper use, they can detect results just as well as the urine tests you'd take at a doctor's office. Appropriate timing is crucial for getting a reliable reading. The best time to take a pregnancy test is after missing your period. Here's why: About six to 10 days after fertilization, the embryo implants in the uterine wall, and your body starts producing hCG. It will take some time to make enough hCG for a positive pregnancy test, says Daniel Roshan, M.D., an OB-GYN at Rosh Maternal-Fetal Medicine in New York City.
