Sensitivity is the proportion of patients with disease who test positive. In probability notation: P(T+|D+) = TP / (TP+FN). Specificity is the proportion of patients without disease who test negative. In probability notation: P(T-|D-) = TN / (TN + FP). Pretest Probability is the estimated likelihood of disease before the test is done. It is the same thing as prior probability and is often estimated.
