  1. Sensitivity: true positive/true positive + false negative*100 = 87.8%
  2. Specificity: true negative/true negative + false positive*100 = 94%
  3. Positive predictive value: true positive/true positive + false positive*100 = 96.6%
  4. Negative predictive value: true negative/true Negative + False positive*100 = 80%
  5. Accuracy: true positive + true negative/total number*100 = 90%
