The NPV is the true negatives divided by the sum of the true negatives and false negatives. The PPV is the true positives divided by the sum the true positives and false positives. The other distractor answers are the positive predictive value and the negative predictive value. Specificity = (true negatives) / (true negatives + false positives) Sensitivity = (true positives) / (true positives + false negatives) The formulas for sensitivity and specificity are as follows:

Sensitivity: 89.11 Specificity: 95.96 ĭ. Sensitivity: 95.96 Specificity: 89.11 Answer and Explanation What is the sensitivity and specificity of this test?Ī. QuestionĤ00 patients take a diagnostic test. So whip out your calculators and let’s get into this week’s practice question. Just scroll down and you should find them. However, if you’re not sure where to begin they are available in the answer and explanation section. We’re not going to include the formulas before the question. It’s the likelihood that those that receive a negative test result do not have the disease. Meanwhile, specificity is the true negative rate. It’s the likelihood that those that receive a positive test result have the disease. If you recall, sensitivity is the true positive rate.
