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.

Agree with Dr. M: If you mean a pregnancy test, a blood test done 4-5 days after a missed period is more than 99% accurate. Have a healthy diet, exercise 30 minutes/day, drink plenty of water, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV vaccine.
