How Do Pregnancy Tests Work?

19 Jul 2021 | Pregnancy Test

A missed period. Fatigue. Sore, tender breasts. Moodiness. Could you be pregnant?

If you’ve been frantically searching pregnancy symptoms on the internet, it’s time to answer your questions with a pregnancy test. But as you peruse the test options at your local drug store, you may be wondering, “How do pregnancy tests work?”

How do pregnancy tests work?

There are two basic types of pregnancy tests: a blood test, and a urine test. Typically a blood test is only taken if recommended by a doctor after a urine test comes back positive. Blood pregnancy tests are more sensitive and can reveal more information about the pregnancy, and are less common than the urine test.

Both types of pregnancy tests work by measuring hCG levels in your blood. This hormone (hCG) is always present in your blood but is much higher during pregnancy. Both urine and blood hCG tests can reliably detect early pregnancy. 

When should I take a pregnancy test?

It is best to wait at least one week after your missed period before taking a pregnancy test for the most reliable results.
