How long after conception can pregnancy be detected?

How Long After Intercourse Can Pregnancy Be Detected? Generally, self-testing for pregnancy can be performed approximately 8 days after intercourse using a home pregnancy test (urine dipstick). The longer the interval between intercourse and testing, the more accurate the result. In summary, pregnancy can typically be detected as early as one week—or up to about three weeks—after intercourse. Home pregnancy tests work by detecting the level of human chorionic gonadotropin (hCG), a hormone produced by the placenta.

Typically, there are numerous methods available to test for pregnancy after conception. The timing at which pregnancy can be detected varies depending on the specific testing method used. - With a home pregnancy test (urine dipstick), pregnancy can generally be detected around 35–40 days after conception. - A urine test performed at a hospital can usually detect pregnancy around 30 days after conception. - A blood test (serum β-hCG assay) can detect pregnancy as early as approximately 28 days after conception.
