A test whichshows the true status of the patient is termed gold standard. These test are assumedto have 100% sensitivity and specificity. Diagnostic power of other tests areevaluated based on the comparison with the gold standard test.When the termapplies to a method or a procedure, a 'gold standard' serves as a basis for evaluationof other methods. -
