Abbreviations: IQR, interquartile range; SI conversions: To convert calcium to mmol/L. multiply by 0.25. To convert magnesium to mmol/L, multiply by 0.411. To convert phosphorus to mmol/L, multiply by 0.323. ^aThe most abnormal value recorded used.

^bDefined as lymphocytes < 1500/μL; lactate dehydrogenase > 190 U/L; creatine kinase > 240 U/L for men and > 190 U/L for women; potassium < 3.5 mEq/L; calcium < 8.8 mg/dL; magnesium < 1.70 mg/dL; phosphate < 2.79 mg/dL.

^cCalcium values have been corrected for serum albumin.
