It is possible to get a false positive test result. This happens when a doctor or laboratory has not performed a confirmatory antibody test before giving people their results. When a person has an antibody test, the lab usually runs two different kinds of tests. One is called an EIA test which is highly sensitive. It can sometimes overreact, so a positive result with the EIA is usually followed up with a RIBA test which is a sophisticated, highly-specific, antibody test. See similar questions...

A positive antibody test could mean one of two things. It could mean that a person is infected with hepatitis C and is a chronic carrier. Or, it could mean that the person was infected with hepatits C but has cleared it from his or her body. An antibody test cannot tell anyone which of those two categories applies. Once infected, you will always have hepatitis C antibodies, and therefore will always test positive on a hepatitis C screening test. See similar questions...

Yes, a false positive test means the test looks as if it is positive, but it is really negative. This happens more often in people who have a low risk for the disease. It is important to confirm the test result a second time. See similar questions...

False negative results are more common than false positives - and are primarily due to inaccuracies in timing of the test or carelessness in the test procedure itself. Please follow test instructions with circumspection and precision. A false negative result can also stem from using a diluted urine sample and/or from taking a test too early in pregnancy. First morning urine contains the most concentrated presence of hCG - which makes it the ideal sample for pregnancy testing. See similar questions...

Yes. A false positive test means the test looks as if it is positive, but it is really negative. This happens more often in persons who have a low risk for the disease for which they are being tested. For example, false positive anti-HCV tests happen more often in persons such as blood donors who are at low risk for hepatitis C. See similar questions...

A "false-reactive" (or "false-positive") test result means that the initial screening test was "reactive" but a more precise follow-up test was negative. See similar questions...

Tests are very accurate but not 100 percent accurate. Usually samples are divided so if an initial test is positive a confirmation test can be conducted. Federal guidelines are in place to ensure accuracy and fairness in drug testing programs. See similar questions...

A false positive hearing screening test result is when a baby does not have a hearing loss but the newborn does not pass the hearing screening. Hearing screening tests are not meant to diagnose hearing loss in infants. Instead, they are meant to find all infants that might have a hearing loss. Because they are not a diagnostic test, hearing screening tests sometimes misidentify infants as having a hearing loss. See similar questions...
