ObjectivesTo determine the relationship between BiliChek TcB (Respironics, Marietta GA) and Doumas reference serum or plasma total bilirubin (TSB).Design and methodsPooled samples with values assigned by the Doumas reference method were used to establish the relationship between a local laboratory and reference Doumas TSB. We then established the relationship between TcB and TSB in the 3 months before and after reassignment of calibrator setpoints undertaken to match the local laboratory to Doumas reference bilirubin values.ResultsBefore calibrator setpoint reassignment TSB as measured in our laboratory overestimated Doumas reference bilirubin. After calibrator adjustment laboratory TSB was within 1.7–6.8 µmol/L (0.1–0.4 mg/dL) of Doumas reference values. Mean bias between BiliChek TcB and TSB was 42.8 ± 22.2 µmol/L (2.5 ± 1.3 mg/dL) (n = 94) before and 49.6 ± 22.2 µmol/L (2.9 ± 1.3 mg/dL) (n = 115) after calibration adjustment.ConclusionsBiliChek TcB significantly overestimates TSB as measured by the Doumas reference method.
