When Qrs Flips From Positive To Negative
Negative blood test for hiv. Possible that it hit window of seroconversion. How often do you see false negatives after 1-2 months?
Never in my career: False negative HIV means there is infection but the antibody test is negative. The situations where this occurs have to do with the timing of the test or continued risky behavior where a person is infected within days after the test. The home kits that use oral fluid are false negative 1 out of 12, according to cdc website on HIV testing. The blood test done at the right time is very accurate. ...Read moreSee 1 more doctor answer
Is it possible to never test pos on a hpt? 9 negatives. Period like bleeding 11/15 and 12/19 each for 3-4 days
If it is uncertain: whether you have MVP on an ECHO or not then it is probably so insignificant that you really shouldn't be worried about it at all. Severe MVP will not be questionable and should be followed. MVP that might be a "false positive" is insignificant. Relax, you probably have a normal valve. ...Read more
I missed my period but tests come back negative. Was 7 weeks along when they came back positive with 1st child. Could it be the same situation?
Trust the test: Home pregnancy tests are very accurate. They are the same tests used in a doctors office. They can detect a pregnancy 7-10 days after conception. The best time to take one is when you miss your period. If you doubt the result you can repeat it in 1-2 days. If you were pregnant the hormone level would rise enough for detection. See doc for irregular periods and birth control. ...Read more

19 weeks pregnat blood came back negative but they can see babys bone in nose does it always mean down syndrome?
Not Down's: The blood test is the gold standard for testing. I would believe that 10 times more than an indistinct shadow on a 19 week ultrasound. There are lots of false positives (meaning a condition is suspected but ends up not being true) with us screening. That's why it is just a screening. If you then have a positive screen, you move ahead to the gold standard test - in this case the blood work or amnio. ...Read more
Please : Please wait two days and re-take another test. By then if you are indeed pregnant, your pregnancy hormone (beta hcg) should have built up.

If you develop pain, vomiting, discharge, or feel light-headed or faint then you would have to be seen immediately. ...Read more
If one takes a pregnancy test when spotting will it result in false positive? Will it be inaccurate because of spotting contamination?
Depends: If you can keep the urine from being contaminated with the "spotting" the test will still be accurate. If you have any doubt, get a blood test for HCG level. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more
