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.
Most early pregnancy tests are only 50 percent accurate on the earliest test day, but they are 99 percent accurate when used the day of your missed period. Be sure to use your first urine of the morning, and to follow the instructions exactly. If your result is negative, it does not mean you are not pregnant.
