Which of the following can be expected as a result of this change?? A: Decrease the sensitivity, B: Decrease the specificity, C: Increase the precision, D: Increase the sensitivity, E: No change to the sensitivity or specificity,  <response>: This is a question about the effects of changing the cut-off for a positive PPD skin test result from 10 mm to 15 mm of induration. The PPD skin test is used to screen for latent tuberculosis infection. Increasing the cut-off for a positive result from 10 mm to 15 mm would decrease the sensitivity of the test, meaning fewer people with true latent TB would test positive. It would increase the specificity, meaning fewer people without true latent TB would test falsely positive. The precision or reproducibility of the test would not change. A: Decrease the sensitivity
