If you think you might be pregnant, you may feel uncertain about what to do next. One of the first steps many women take is using a pregnancy test, but how do these tests actually work? Understanding the science behind pregnancy testing can help you feel more confident as you move forward.
At True Care Women’s Resource Center, we offer no-cost, confidential pregnancy testing and support to help you find answers. Keep reading to learn what you need to know.
What Does a Pregnancy Test Detect?
Pregnancy tests detect a hormone called human chorionic gonadotropin (hCG). This hormone is produced by the placenta shortly after a fertilized egg attaches to the uterus’s lining. Once implantation occurs, hCG increases rapidly, doubling every 48 to 72 hours in early pregnancy.
When you take a pregnancy test, whether at home or the doctor’s office, the test looks for detectable levels of hCG in your body. A positive result typically indicates that your body is producing hCG, which is a strong sign of pregnancy.
When Can I Take a Pregnancy Test?
Testing too early in your pregnancy may lead to a false-negative. That’s because hCG has not yet risen to detectable levels, so you may not realize you’re pregnant when you actually are.
The Mayo Clinic notes that it’s best to take a pregnancy test after you miss your period. This gives any hCG in your body time to build, increasing your chances of receiving an accurate result.
Types of Pregnancy Tests
It’s essential to learn about each kind of pregnancy test before moving forward:
- Urine tests: These tests can be taken at home and are available at pharmacies and grocery stores. They are highly accurate, but receiving a reliable result hinges on following the directions and taking the test at the recommended time.
- Blood tests: Offered at a doctor’s office, clinic, or hospital, these tests can detect pregnancy earlier than urine tests and determine the specific level of hCG in your body. However, they are less commonly used unless recommended by your healthcare provider.
At True Care, we offer urine pregnancy testing at no cost. We’ll provide an ultrasound to confirm your pregnancy if your test is positive.
