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. ...Read more

Can you tell me in diagnosing malaria, if the first blood test is negative, what chances are there that the person has the disease?

Can you tell me in diagnosing malaria, if the first blood test is negative, what chances are there that the person has the disease?

Pretty good: The level of parasites in the blood may be quite low at first. The familiar microscopic study with a giemsa stain is difficult and requires a lot of experience and skill.

What if I took the blood test a day after implantation. Could I've gotten. A false negative because I took it to early. Also before Af came?

What if I took the blood test a day after implantation. Could I've gotten. A false negative because I took it to early. Also before Af came?

Too early to test: Conception, as defined by the generation of a fertilized ovum, occurs within day or so of the sex. However, it takes about two weeks for the embryo to make enough HCG to produce a positive pregnancy test. Blood test may be done a day after a missed period. Home pregnancy tests should be done 4-5 days after the missed period. Use first morning urine and follow instructions for the test carefully. ...Read more

Was not needed: If you did the tests correctly and did those more than three weeks after the last episode of sex, you probably did not need the blood test. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat 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.
