A "one-minute" direct bilirubin determination using the Abbott ABA-100 Bichromatic Analyser.

We describe a "one-minute" direct bilirubin procedure using the ABA-100. The procedure correlates well with the manual Jendrassik-Grof method and gives good precision at a relatively low direct bilirubin level. In comparison with certain other Abbott ABA-100 direct bilirubin methods, the proposed procedure appears to be the least affected by the presence of high unconjugated bilirubin levels.
