A 'false positive' can occur on a
home pregnancy test. This result means that the at-home testing results report that the woman is pregenant when she is, in fact, not. At-home pregnancy tests are sometimes sold in 2-packs for women to use both tests at the same time. Testing differently using the same method at the same time is an indication of a false positive or
false negative result.
A false positive may occur if the woman has levels of
hCG in her blood from a recent pregnancy or miscarriage. It can also occur if you are receiving
fertility injections to induce
ovulation.
In
biometrics, this term refers to the case where an
authentication system erroneously
grants access to an
authorized entity.
