What to know about home pregnancy test kit accuracy?

You have suspicions that you may be pregnant, so the first thing you do is run to the drugstore and grab a pregnancy test — or two. Although home pregnancy test kits are more than 99% accurate when used correctly, women often doubt the results and tend to retest.

But really, modern science has brought us far, and home pregnancy test kits are pretty accurate. To ease your mind, we’ve answered some common questions you might have about home pregnancy test kits and what you should know about their accuracy.

When should I use a home pregnancy test kit?

While many tests claim to be able to tell pregnancy from the first day of a missed period, it is advisable to wait at least a week after a missed period to test. This is because home pregnancy test kits may not be as accurate at the start of a pregnancy, as some women develop detectable amounts of pregnancy hormones later than others do.

If you’re collecting urine, do the test within 15 minutes of collecting the sample. Give the test time to work, and check the box to see how long the test takes. You may want to set a timer according to the package instructions. For the most accurate results, take the test first thing in the morning when your urine is the most concentrated.
