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 are unsure about your results, you should make an appointment with your doctor so he or she can confirm the results with a blood test. Urine tests just show positive or negative. They cannot tell you how far along the pregnancy is. Home pregnancy tests, if done correctly, can be 99 percent accurate. However, many women test too early in their cycles, not allowing enough time for hCG to build up in the system.
