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.
These tests, available commercially, are very accurate for the most part when used at the right time. Home pregnancy tests (HPTs) are most accurate when used one week after a missed menstrual period. However, as mentioned previously, some women do not experience implantation until a later time. These women, a smaller percentage, are indeed pregnant, but their HPT may be negative. This can cause some confusion and worry.
