A blood test can detect pregnancy earlier than a home pregnancy test, as it can detect lower levels of the hormone human chorionic gonadotropin (hCG) in the blood. hCG is produced by the placenta after a fertilized egg has implanted in the uterus, and its levels increase rapidly in early pregnancy.
A blood test for pregnancy can typically detect hCG levels within 11 days after conception. However, the timing can vary depending on the woman's individual cycle and the sensitivity of the test being used.
It is important to note that while blood tests can detect pregnancy earlier than home pregnancy tests, they are also more expensive and less convenient. Home pregnancy tests are generally accurate and can detect pregnancy after a missed period, which is usually around 2 weeks after conception.
