Sensitivity – of a test or drug

sensitivity – when referring to the accuracy of a test result, sensitivity refers to the proportion of people with an illness or disease who have a positive test result.

If a test has low sensitivity, then false-negative results are the concern – where people have a condition but it is missed.

If a test has high sensitivity, then people are accurately diagnosed – and only a few people are missed.

For a serious condition, high sensitivity is essential to be able to identify people early.
