The following are multiple choice questions (with answers) about medical knowledge.   **Question:** Accurate and rapid identification of individuals with tuberculosis (TB) is crucial to accomplishing the goal of the World Health Organization (WHO) to eliminate this disease. One of the key strategies for the detection of TB is the use of tuberculin skin testing as a globally pertinent screening method, due to its low cost and technical simplicity. A study from Brazil demonstrated 76.7% accuracy, 67.9% sensitivity, 84.4% specificity, 79.1% positive predictive value, and 75% negative predictive value when using 5-mm skin elevation as a threshold, or cut-off, point for the screening test (following intradermal injection). Lowering the cut-off point to 4 mm would also result in an increase in which test property?   (A) Convergent validity   (B) Discriminant validity   (C) Negative predictive value   (D) Test specificity
