The short answer

How accurate are home pregnancy tests? The good news is, very, about ninety-nine percent, when they're used correctly. The catch is in those last two words. Most wrong results come down to how and when the test was taken. Let me show you how to get a reliable answer.

Very accurate — when you use them right

They detect hCG — which takes time to build up

Home tests work by detecting a pregnancy hormone called hCG in your urine. After a fertilized egg implants, hCG starts low and roughly doubles every couple of days. So early on, there may simply not be enough hormone yet for the test to catch.

Testing too early = the #1 cause of false negatives

That's why testing too early is the number one cause of a false negative, a negative result when you actually are pregnant. For the most accurate result, wait until the day your period is due, or a few days after. If it's negative but your period still doesn't come, test again in a couple of days.

False positives are rare

What about a false positive, a positive when you're not pregnant? That's rare. It can happen with a very early loss called a chemical pregnancy, certain fertility medications, or misreading a faint evaporation line. But in general, a clear positive is very trustworthy.

Best result: first-morning urine, after a missed period

For the most reliable result, use your first-morning urine, when hCG is most concentrated, test after your period is late, and follow the timing on the instructions before reading it. Then confirm a positive with your doctor, who can verify it and start your care.

So, to recap: home pregnancy tests are about ninety-nine percent accurate when used correctly, but they detect hCG that takes time to build, so testing too early causes false negatives. False positives are rare. For the best result, use first-morning urine after a missed period, and confirm a positive with your doctor.
