The lecture False Positives and False Negatives – Screening Tests by Raywat Deonandan, PhD is from the course Screening Tests.
You estimate that the patient in your office has a one in four chance of having a serious disease. You order a diagnostic test with sensitivity of 95% and specificity of 90%. The result comes back positive. Based on all the information now available, what is the chance your patient really has the disease?

A screening test is developed for disease X. What do we call the probability that the test will correctly identify someone who truly does not have disease X?
