How Does a Pregnancy Test Work?

If you think you might be pregnant, a pregnancy test is the first step toward getting clarity. While many start with an at-home test, confirming that result with a high-quality test is critical to move forward.

Pregnancy tests look for the presence of a hormone called human chorionic gonadotropin (hCG). This hormone builds in your body shortly after a fertilized egg attaches to the uterus and the placenta begins to develop.

A positive test result means hCG levels in your system have reached a point that they can be detected.

When Is the Right Time to Test?

Most women take a test when they notice early pregnancy symptoms like a missed period or nausea. While these signs can point to pregnancy, they’re not definitive, so testing is the only way to be sure.

The Mayo Clinic recommends waiting until at least one or two days after your missed period for the most reliable results. This gives hCG time to rise to a detectable level in your body.

Additionally, testing first thing in the morning can boost accuracy since urine is typically more concentrated.

What Should I Do if the Test Is Positive?

If your test is negative, it might be because it’s too early to detect hCG. Wait a few more days before testing again, and be sure to follow all instructions carefully.

If your result is positive, remember you still need more information to confirm a pregnancy. Your first step is to take advantage of a pregnancy test at Care Net of Carbon County to verify your initial result. Tests are self-administered, but our nurses perform them whenever possible.

If your result is confirmed, you might also qualify for a limited OB ultrasound. This scan offers vital information, such as the pregnancy’s location and gestational age, helping you move forward with more clarity and confidence.
