Jessica takes a prenatal development test, alpha-fetoprotein (AFP), that indicates her fetus may have a problem. Later, it is found that the fetus is normal. The result of the test is known as a:

False positive

Explanation:

A false positive is a type of error that occurs in data reporting, whereby a test result falsely reports the presence of a condition, for instance a disease, when the condition is not present in reality. It can also be referred to as a false alarm, as the test result shows positive (presence of a disease), when in actual fact it is negative (absence of a disease).

Jessica's first result indicated the presence of a problem when in actually fact there was no problem, this means the first result was false positive.
