About the Episode
Screening tests look for risk signals in people without symptoms; diagnostic tests prove disease; monitoring tests track disease course. The three are often confused. This episode discusses what 'positive' and 'negative' results really mean, the concepts of sensitivity and specificity, and the limits of screening tests.
The takeaway: a screening test is a starting point; a diagnosis is made through clinical examination and diagnostic methods.
