Which Home Pregnancy Tests are Most Accurate?
Most home pregnancy tests on the market today claim to be more than 99 percent accurate when taken correctly. What they don't tell you, however, is whether they're as accurate on the day you miss your period as they are 5 to 7 days later. So how do you know which home pregnancy test will give you the most reliable result when you want it?
Home pregnancy tests are designed to detect hCG, a hormone secreted by the cells that will become the placenta. If you are pregnant, your hCG levels will increase rapidly almost immediately following implantation, and will double every 2 to 3 days for about 10 weeks. The tests that detect the lowest concentration of hCG (in milli-International Units per milliliter of urine) are more sensitive to hCG and will give you the earliest reliable results. For example, tests that can detect 20 mIU/ml are more sensitive than those that can detect 50 to 100 mIU/ml.
The chart below lists 25 home pregnancy tests currently on the market. The tests with the lowest hCG levels should be able to detect pregnancy sooner than those rated for a higher level.
