How is the Accuracy of a Diagnostic Test Determined?
The accuracy of a diagnostic test is determined by comparing its results with a gold standard or a reference test that is considered definitive. The two main components of accuracy are sensitivity and specificity.
Sensitivity: This is the ability of the test to correctly identify those with the disease (true positive rate). Specificity: This is the ability of the test to correctly identify those without the disease (true negative rate).
