FerriScan® Product Specifications

Sensitivity and Specificity

The FerriScan analysis has the highest sensitivity and specificity for predicting LIC measured from biopsy over the entire LIC range encountered in clinical practice.

LIC Threshold1 Clinical Relevance2 Sensitivity %3 Specificity %3
1.8 Upper 95% of normal 94%
3.2 Suggested lower limit of optimal range for LICs for chelation therapy in transfusional iron loading 94%
7.0 Suggested upper limit of optimal range for LICs for transfusional loading and threshold for increased risk of iron-induced complications 89%
15 Threshold for greatly increased risk for cardiac disease and early death in patients with transfusional iron overload 85%

1 LIC Threshold measured in (mg Fe/g dw).
2 Clinical Relevance taken from Olivieri and Brittenham, Blood 1997; 89:739-61.
