Pregnancy tests with a sensitivity of 20 mIU/ml are more sensitive than tests with 50 to 100 mIU/ml. Test brands will display how sensitive their tests are using mIU as the standard unit of measure. Test sensitivity equates with early-detection - and the lower the number, the sooner a test can detect pregnancy. The most sensitive pregnancy tests can detect hCG levels at as low as 20 mIU - or at around 8 days following implantation of the egg.
