In this article, the author reviews the fundamental concepts in diagnostic testing, sensitivity, and specificity and how they relate to the concept of high-value care. The topics are discussed in common language, with a minimum of jargon and mathematics, and with clinical examples. Emphasis is given to conceptual understanding. A companion article will follow focusing on predictive value and prior probability.
