The specificity of a test is its ability to designate an individual who does not have a disease as negative. A highly specific test means that there are few false positive results.

If the critical point occurs soon after the start of the detectable preclinical phase, screening may be too late to be helpful. Sensitivity and specificity are measures of a test’s ability to correctly classify a person as having a disease or not having a disease. Sensitivity refers to a test’s ability to designate an individual with disease as positive. A highly sensitive test means that there are few false negative results, and thus fewer cases of disease are missed.
They cannot be available only at academic or other large medical centers. The tests must not have associated morbidity or mortality—even minor side effects may offset the benefits of screening. The test must also be reasonably priced, otherwise insurers may not provide coverage, and patients may be unable or unwilling to pay for the tests themselves. The disease being screened for must be serious enough to warrant testing asymptomatic people. The disease should be one that, if not found in its detectable preclinical phase before the critical point, will become life-threatening or cause significant morbidity.
The purpose is to identify at-risk individuals and offer them screening and treatment if necessary. Screening tests must be widely available to the population for which they are intended.
