Net Sensitivity Calculator

Formula

The formula to calculate Net Sensitivity is:

\[ NS = \frac{TP}{TP + FN} \times 100 \]

Where:

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

What is Net Sensitivity?

Net Sensitivity is a measure used to evaluate the performance of a diagnostic test. It is defined as the ratio of true positives to the sum of true positives and false negatives, multiplied by 100. This metric indicates the proportion of actual positives that are correctly identified by the test.

Example Calculation 1

Let's assume the following values:

True Positives (TP) = 80
False Negatives (FN) = 20

Using the formula:

\[ NS = \frac{80}{80 + 20} \times 100 = 80\% \]

The Net Sensitivity is 80%.

Example Calculation 2

Let's assume the following values:

True Positives (TP) = 50
False Negatives (FN) = 50

Using the formula:

\[ NS = \frac{50}{50 + 50} \times 100 = 50\% \]

The Net Sensitivity is 50%.
