Verifying the nonreporting hemolysis index for potassium, phosphate, magnesium, AST, LDH, iron, CA 19-9, and vitamin D, using Beckman Coulter AU5800 and DxI800 automated analyzers.

The results from this experiment support increasing the HI nonreporting limit to 100 mg/dL for potassium; 200 mg/dL for magnesium; and 300 mg/dL for phosphate, CA19-9, and vitamin D. The iron assay is not affected by hemolysis as high as 500 mg/dL. The current HI nonreporting limit of 50 mg/dL is appropriate for LDH.
