A pregnancy test detects whether your body has begun producing a specific hormone that is usually only present during pregnancy. If you’re waiting for results or trying to make sense of a positive or negative test, understanding how pregnancy tests work can help you know if you can trust the result.

The Role of hCG
Pregnancy tests work by detecting human chorionic gonadotropin (hCG), a hormone produced after a fertilized egg implants into the uterine lining. Implantation typically occurs about 6–10 days after ovulation. Only after implantation begins does hCG enter the bloodstream and urine.
Because hCG is not present immediately after fertilization, testing too early can result in a false negative. This is why many tests recommend waiting until the first day of a missed period or later, when hormone levels are more likely to be detectable.
How Home Pregnancy Tests Work
Home pregnancy tests identify hCG in urine once it reaches a detectable level. When the hormone reaches a certain threshold, the test shows a positive result. While home tests can be convenient, their accuracy depends on several factors, including:
- How early the test is taken
- The sensitivity of the test
- Proper test use
- Natural variation in hCG levels
A positive home test suggests pregnancy, but it does not provide details about the health or progression of the pregnancy.
Why Medical-Grade Testing Matters
A lab-quality pregnancy test can detect lower levels of hCG and provide more reliable results. However, even lab tests cannot answer critical medical questions on their own.
That’s where ultrasound plays an important role. An ultrasound can help confirm:
- Whether the pregnancy is progressing with a heartbeat
- The location of the pregnancy (to rule out ectopic pregnancy)
- Approximately how far along you are in your pregnancy (gestational age)
This information is essential for understanding your options and next steps.
