| Â | Presence of disease | ||
|---|---|---|---|
Disease Present (Meets NCCN Criteria on CGC Review) | Disease Absent (Does not meet NCCN Criteria on CGC Review) | Total | |
Test outcome | |||
 Positive (Meets NCCN Criteria by digital ID tool) | 382 (A) | 2 (B) | 384 |
 Negative (Does not meet NCCN criteria on digital ID tool) | 0 (C) | 381 (D) | 381 |
 Total | 382 | 383 | 765 |
| Â | Formula Used | Calculation | Value a |
Sensitivity | A/(A + C) | 382/382 | 100% |
Specificity | D/(D + B) | 381/383 | 99.48% |
Accuracy | (A + D)/(A + B + C + D) | 763/765 | 99.74% |
