Quizplus · Accepted Answer

Reliability and validity are key criteria for evaluating the quality of diagnostic tests. A diagnostic test must be reliable (produce consistent results under consistent conditions) and valid (accurately measure what it is supposed to measure) to be considered effective. While some tests may have poor reliability or validity, it is not accurate to generalize that the reliability and validity of diagnostic tests are often quite poor.
