HepaFatSmart® Product Specifications
Sensitivity and Specificity
The diagnostic accuracy of HepaFatSmart® for predicting HepaFatScan® steatosis grading has been tested prospectively on over 1,000 scans 1 . The table indicates the sensitivities and specificities of HepaFatSmart® for predicting steatosis grades as evaluated by the FDA approved and validated HepaFatScan® method 2, 3.
| Steatosis Grades | Grade ≥ 1 | Grade ≥ 2 | Grade = 3 |
|---|---|---|---|
| Sensitivity (95% conf interval) | 1.00 [0.97 – 1.00] | 0.98 [0.93 – 0.99] | 1.00 [0.93 – 1.00] |
| Specificity (95% conf interval) | 0.98 [0.94 – 0.99] | 0.98 [0.94 – 0.99] | 0.99 [0.97 – 0.99] |
