Sensitivity is the proportion of true positive results (people with the disease who test positive), so it measures how well a test detects the disease among those who have it. Specificity, on the other hand, is the proportion of true negative results (people without the disease who test negative), which measures how well a test identifies those who don't have the disease. Accuracy is a measure of how well a test correctly classifies both positive and negative results. Positivity and negativity refer to the presence or absence of a positive test result, respectively. Therefore, sensitivity is the best choice because it directly relates to the ability of the test to correctly identify those with the disease.
