Sensitivity and Specificity Calculator

This calculator is designed for healthcare professionals and researchers to compute the sensitivity and specificity of diagnostic tests. It aims to aid in evaluating the effectiveness of medical tests.

Calculator

Results

Sensitivity: 0%
Specificity: 0%

Data Source and Methodology

All calculations are based on standard formulas found in medical literature, ensuring accuracy and reliability for diagnostic evaluation.

The Formula Explained

Sensitivity: \( \text{Sensitivity} = \frac{TP}{TP + FN} \times 100 \)

Specificity: \( \text{Specificity} = \frac{TN}{TN + FP} \times 100 \)

Glossary of Variables

How It Works: A Step-by-Step Example

Consider a test with 80 true positives, 20 false positives, 85 true negatives, and 15 false negatives. The sensitivity would be calculated as (80 / (80 + 15)) × 100 = 84.21%, and the specificity as (85 / (85 + 20)) × 100 = 80.95%.

Frequently Asked Questions (FAQ)

What is sensitivity in diagnostics?

Sensitivity is the ability of a test to correctly identify those with the disease (true positive rate).

What is specificity?

Specificity is the ability of a test to correctly identify those without the disease (true negative rate).

How are sensitivity and specificity calculated?

Sensitivity is calculated as the number of true positives divided by the sum of true positives and false negatives. Specificity is calculated as the number of true negatives divided by the sum of true negatives and false positives.
