The initial reporter stated they received discrepant results for three patient samples tested for multiple analytes on the cobas pro c 503 analytical unit.Results from the following assays were affected: gluc3 glucose hk gen.3, hdlc4 hdl-cholesterol plus 4th generation, crep2 creatinine plus ver.2, ua2 uric acid ver.2, and chol2 cholesterol gen.2.No incorrect results were reported outside of the laboratory.The repeat values were comparable to previous results of the patients.The first patient sample initially resulted in a glucose value of 38.0 mg/dl, which repeated as 77.9 mg/dl.The second sample initially resulted in an hdl value of 42.2 mg/dl, which repeated as 68.1 mg/dl.The second sample initially resulted in a glucose value of 42.3 mg/dl, which repeated as 115 mg/dl.The second sample initially resulted in a creatinine value of 0.449 mg/dl, which repeated as 1.14 mg/dl.The second sample initially resulted in a uric acid value of 4.29 mg/dl, which repeated as 5.83 mg/dl.The third sample initially resulted in a cholesterol value of 85.7 mg/dl, which repeated as 179 mg/dl.The glucose reagent lot was 551267, the hdl reagent lot was 530537, the creatinine reagent lot was 577467, the uric acid reagent lot was 574816, and the cholesterol reagent lot was 559813.The reagent expiration dates were requested, but not provided.
