Doctors often order these tests to confirm pregnancy as early as 10 days after a missed period. However, some of these tests can detect hCG much earlier. A quantitative hCG test (beta hCG) measures the exact amount of hCG in your blood. It can find even very low levels of hCG.
At What Point Can a Blood Test Determine Whether or Not a Woman is Pregnant? Blood tests are able to detect pregnancy about 7 to 12 days after conception, making them a better option than most at home pregnancy tests. Unlike home pregnancy tests, they can also determine the level of hCG in your blood. This is particularly useful information for your doctor because it can help reveal information about specific problems commonly experienced during pregnancy.
