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.
Home pregnancy tests tend to be more accurate if you leave it a few days after you should have had your period; very few tests are 100 percent accurate on the first day of a missed period, and research suggests that accuracy is only around 80 percent at this time.
