Objectives: To assess the performance of the Doumas bilirubin reference method.

Design And Methods: Ring trails using pooled patient specimens, a calibrator and human sera enriched with unconjugated bilirubin were analyzed in five laboratories using the Doumas bilirubin reference method.

Results: The coefficient of variation for the linear measurement range between laboratories ranged from 1-3%.

Conclusions: The Doumas bilirubin reference method is robust and reproducible. Bilirubin results using this method may be used in the development of more accurate and reliable calibrators.

Background: For the determination of total bilirubin in serum the candidate reference method developed by Doumas et al. has international recognition. The primary standard SRM 916a (NIST) was recommended for use as the primary reference material for calibration.

The status of bilirubin measurements in U.S. laboratories: why is accuracy elusive?

In 2003, the Chemistry Resource Committee of the College of American Pathologists introduced a new specimen in the Neonatal Bilirubin Survey. The specimen, consisting of human serum enriched with unconjugated bilirubin and thus resembling a clinical specimen, brought about an improvement in the accuracy of the measurement of bilirubin by laboratories participating in the Neonatal Bilirubin Survey. There was also an improvement in the specificity of methods measuring direct bilirubin.

Objectives: To determine the relationship between BiliChek TcB (Respironics, Marietta GA) and Doumas reference serum or plasma total bilirubin (TSB).

Design And Methods: Pooled 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.
