Predictive value of tests


Predictive value of tests is the probability of a target condition (for example a disease) given by the result of a test, often in regard to medical tests.

A conversion of continuous values into binary values can be performed, such as designating a pregnancy test as "positive" above a certain cutoff value, but this confers a loss of information and generally results in less accurate predictive values.
