For a positive pregnancy blood test, hCG levels typically need to be at least 5 mIU/mL. Levels between 5-25 mIU/mL are considered borderline, and levels above 25 mIU/mL are definitively positive. Remember, hCG levels vary widely among individuals and stages of early pregnancy, so it's often recommended to repeat the test after a few days if initial levels are low but pregnancy is still suspected.
