Sensitivity (true positive) = number of true positives/number of true positives + number of false negatives. Specificity (true negative) = number of true negatives/number of true negatives + number of false positives. Positive predictive value = number of true positives/number of true positives + number of false positives. Negative predictive value = number of true negatives/number of true negatives + number of false negatives.
