How the Test Works

Your urine sample is tested for hCG, the hormone that signals pregnancy. A positive result means hCG is detected, which may indicate pregnancy. The test is highly sensitive and can detect early pregnancy changes.

When to Take This Test

This test is typically taken at the first sign of possible pregnancy, often as early as 7–10 days after conception. Some tests can detect hCG as early as a few days after a missed period, but accuracy improves with later testing.

What to Expect Before the Test

No special preparation is needed. You may urinate into a clean container or use a home pregnancy test kit if ordered by your provider. For lab tests, follow your healthcare provider’s instructions for specimen collection.

What to Expect After the Test

Results are usually available immediately for home tests or within hours/days for lab tests. A positive result requires confirmation with a healthcare provider, especially if you’re unsure about other symptoms.

Clinical interpretation
