| Term | Definition | Formula |
|---|---|---|
| Sensitivity | The ability of a test to detect disease | TP ÷ (TP+FN) |
| Specificity | The ability of a test to identify normality | TN ÷ (FP+TN) |
| Positive Predictive Value | The percentage of non-invasive tests which accurately predict abnormality | TP ÷ (TP+FP) |
| Negative Predictive Value | The number of non-invasive tests which accurately predict normality | TN ÷ (TN+FN) |
| Accuracy | The overall percentage of correct non-invasive diagnoses (how well does your lab detect and rule out disease?) | (TP+TN)÷(TP+FP+TN+FN) |
