Beckman Coulter Inc. recalls UIBC (Unsaturated Iron Binding Capacity)

Beckman Coulter identified that the Unsaturated Iron Binding Capacity (UIBC) assay is not meeting their labeled hemoglobin interference claims of no significant interference (i.e., less than 10%) up to 200 mg/dL hemoglobin as indicated in their instructions for use. Initial internal testing confirmed that samples with low UIBC levels failed the claimed hemolysis interference specifications with reported biases up to -43.6 % UIBC when hemolyzed serum samples contained 200 mg/dL hemoglobin.
