Enter the true positive and the false negative into the Calculator. The calculator will evaluate the Net Sensitivity. 

Net Sensitivity Formula

NS = TP / (TP+FN) * 100


  • NS is the Net Sensitivity (%)
  • TP is the true positive
  • FN is the false negative

To calculate Net Sensitivity, divide the true positives by the number of true positives and false negatives, then multiply by 100.

How to Calculate Net Sensitivity?

The following steps outline how to calculate the Net Sensitivity.

  1. First, determine the true positive. 
  2. Next, determine the false negative. 
  3. Next, gather the formula from above = NS = TP / (TP+FN) * 100.
  4. Finally, calculate the Net Sensitivity.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :
