A member asked:
Is it ever that a blood test be false?
A doctor has provided 1 answer
Yes, depends on test: Some tests are initial screening tests which are designed to "flag" anyone who has a condition. Because of this design (high sensitivity test), there are probably some people without the condition tested who also may "flag" positive (false positive) on that test. These findings require repeat or confirmatory testing to ensure that the diagnosis is correct (true positive).
