DIAG2-S Deciding If and When To Screen or Test (S004-DIAG2)


Description
Just because a screening or diagnostic test is available doesn't mean it should be ordered for a patient. This module walks through the risks of indiscriminate use of tests, including the detrimental effect of false positive tests and the consequences of early diagnosis of disease and the concept of overdiagnosis.
