What is sensitivity specificity and accuracy?

Sensitivity is defined as follows: TP/(TP + FN) = (Number of genuine positive assessments)/ (Number of all positive assessment) (Number of true negative assessments)/(TN + FP) = Specificity (Number of all negative assessment) Accuracy is calculated as follows: (TN + TP)/(TN+TP+FN+FP) = (Number of accurate assessments)/(Number of all assessments)

What does a sensitivity of 70% mean?

Predictive Values, both positive and negative With a 70% NPV, 7 out of 10 negative results would properly reflect the absence of the illness (known as “true negatives”), while the remaining 3 results would represent “false negatives,” which would indicate that the patient really had the condition but the test failed to detect it.
