Blood tests can find hCG six to eight days after ovulation, and in most cases urine tests take about two weeks after ovulation. hCG is measured in thousandths of International Units, or mIU. Pregnancy tests with a sensitivity of 20 mIU/ml are more sensitive than tests with 50 to 100 mIU/ml.ome pregnancy tests, if done correctly, can be 99% accurate. However, many women test too early in their cycles, not giving enough time for hCG to build up in her system. Itâs best to take the test after you have missed a period, or 14 days after ovulation.
