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.
If you use a home pregnancy test too early in your pregnancy, you may not have enough of the pregnancy hormone hCG in your urine to have a positive test result. Most HPTs will be accurate if you test yourself around the time your period is due (about 2 weeks after you ovulate, or release an egg from your ovary).
