Learning the Basics
Pregnancy tests work by detecting a hormone called human chorionic gonadotropin (hCG), which your body starts producing shortly after a fertilized egg implants in the uterus and the placenta begins forming.
As the pregnancy progresses, hCG levels rise quickly, doubling every few days in those early weeks. However, if you test too soon, there may not be enough of the hormone present for an accurate result. For this reason, many healthcare providers recommend waiting until after your missed period to take a test.
Comparing Urine and Blood Tests
There are two main types of pregnancy tests: urine tests and blood tests.
Urine tests are commonly used, easy to find, and can be done privately at home. They detect hCG in your urine and provide a result within minutes. While highly effective, they can produce false-negative results if taken too early or incorrectly.
Blood tests, however, are performed in a doctor’s office or hospital. They’re more sensitive than urine tests and can detect hCG earlier in pregnancy. Healthcare providers use these tests to monitor hormone levels over time or confirm at-home results.
Knowing When and How to Test
Some women take a test after missing a period or noticing signs like nausea or fatigue. However, not everyone has a predictable cycle. If your periods are irregular, timing a test correctly can be tricky. A healthcare provider can help determine the best time to test based on your unique situation.
If you choose an at-home test, follow the directions carefully. Testing in the morning, when hCG levels are most concentrated in your urine, may improve accuracy.
