how soon is a pregnancy test accurate

A pregnancy test can be accurate as soon as 10 days after conception, depending on the test's sensitivity to the pregnancy hormone hCG. Most home pregnancy tests are reliable starting from the first day of a missed period, which is typically about 14 days after ovulation. Blood tests can detect pregnancy even earlier, within 7 to 10 days after conception, because they detect lower levels of hCG than urine tests. Testing too early may lead to false negatives due to insufficient hCG levels in urine. For best accuracy, it's recommended to test on or after the day of the expected period, ideally using first-morning urine for higher concentration of hCG.
