Two Pregnancy Tests - Different Results

    Q: I took two different pregnancy tests and got two different results. What happened?

    A: This can happen specifically when you test very early in pregnancy. For example, one brand only needs a level of 25 mIU hCG to show a positive test, while at the same time, another brand will need 50 mIU hCG to be positive.
    That could explain why on one test is positive and the other test is negative.
    Doing a blood hCG level or repeating the urine pregnancy test two to three days later will usually give a clearer answer.
