What is a 'gold standard'?
The term 'gold standard' can be referred to a test or a method. A test which
shows the true status of the patient is termed gold standard. These test are assumed
to have 100% sensitivity and specificity. Diagnostic power of other tests are
evaluated based on the comparison with the gold standard test.When the term
applies to a method or a procedure, a 'gold standard' serves as a basis for evaluation
of other methods.
