In order to determine the probability of a positive test result being accurate, one needs to consider all three factors: the base rate, sensitivity of the test, and specificity of the test. The base rate refers to the prevalence of the condition being tested in the population. The sensitivity of the test refers to the proportion of true positives that the test accurately identifies. The specificity of the test refers to the proportion of true negatives that the test accurately identifies. Only by considering all three factors can one accurately determine the probability of a positive test result being accurate.
