What does "Accuracy" mean in a report or doctor's letter? In our medical dictionary, you will find a patient-friendly explanation of the meaning of this medical term.
Accuracy in medicine refers to how close a test result is to the true condition of a person. For example, if a test is designed to detect a certain disease, its accuracy would be how often it correctly identifies people with and without the disease. A highly accurate test would rarely give a false positive (saying someone has the disease when they don't) or a false negative (saying someone doesn't have the disease when they do).
