Or, you may harbor anti anti IgA heterophile antibody which can give spurious results. Check with your gynecologist to be sure. ...Read more

I went to a clinic and got a pregnancy test done, it was positive. I went to the ER. They did a blood test and it was negative. Could I be pregnant?

Great question: The sensitivity of tests can vary a great deal. This results in what we call false positive and false negative results which vary with the sensitivity and specificity of the tests. In a case like this I would repeat the tests in one week. That will usually result in both tests agreeing. Either way, be safe and follow healthy guidelines. Good luck! ...Read more
