Q: How accurate are home pregnancy tests? A: Most manufacturers claim that their tests are 97 to 99 percent accurate, but a test can be less effective if it's not used properly, used beyond its expiration date, or exposed to sunlight. To be sure you get the best results, read the instructions thoroughly before starting the test and follow them exactly.
A positive home pregnancy test means that you are pregnant. Home pregnancy tests work by measuring HCG (human chorionic gonadotropic, the pregnancy hormone) in the urine. Unlike blood tests for HCG, which measure the actual amount of hormone, home pregnancy tests just register the presence or absence of HCG. A positive result is quite accurate because the test will not register the presence of HCG unless it is actually there. If your test is positive, you are pregnant. Keep in mind that a home test only measures the presence or absence of HCG. It cannot tell you whether a pregnancy is healthy or whether you have had a miscarriage. You can have a miscarriage and your pregnancy test will remain positive for days or even weeks.
