Is it common for woman to get a false negative for blood test? I have read many story's with woman which this has occurred
What blood test? False negatives, as well as false positives, can occur with any test, but most tests have a very low rate of both. In some cases, a false negative can be caused by bad timing. For example, if a pregnancy test or an HIV test is done too early, it may be negative even if the person is actually pregnant or infected with hiv.
