We compared data obtained with the Kodak Ektachem and Hitachi 717 Analysers and HPLC from 83 neonates under phototherapy. Total bilirubin values determined with the Kodak and Hitachi are in good agreement, but we observed a large discrepancy in the results for conjugated (Kodak) and direct (Hitachi) bilirubin. HPLC revealed that all the samples contained configurational isomers, while only 7.7%...
OBJECTIVES The aim of this study was to compare the operational impact of using vanadate oxidase versus diazo direct bilirubin assays for an academic medical center patient population. DESIGN AND METHODS Retrospective study was done over an approximately 3.5 year period. The main automated chemistry instrumentation was a Roche Diagnostics cobas 8000 line. The Roche Direct Bilirubin assay was ...
The study aimed to assess the association between total, direct, and indirect bilirubin and nonalcoholic fatty live disease (NAFLD) risk given its high prevalence and serious clinical prognosis. Among 27,009 subjects who participated in a healthy screening program from the Dongfeng-Tongji cohort study in 2008, 8189 eligible subjects (aged 35-86 years; males, 43.95%) were ultimately enrolled. Th...
We evaluated the American Monitor Corporation kit for total and direct-reacting bilirubin and found that it suffers serious deficiencies, which lead to inaccurate and imprecise results. The main problem with the total-bilirubin procedure is that the short reaction time (2 min) is inadequate for completion of the reaction. The poor precision of the direct-bilirubin method is due to the short rea...
We compared five methods for the determination of total and direct bilirubins in serum samples from normal controls, subjects with Gilbert's syndrome, and serum pools containing about 50 and 150 mg of total bilirubin per liter. The Kodak Ektachem method and a diazotized sulfanilic acid method with 0.15 mmol/L sodium nitrite concentrations are the only methods that gave accurate direct bilirubin...
Background: Despite observed post Sulfur Mustard (SM) exposure hemolysis, serum bilirubin concentration doesn’t significantly increase in SM-exposed casualties. The concentration of serum bilirubin can be related to serum levels of inflammatory cytokines. Objectives: In this study, the relationship between the serum levels of Interleukin (IL)-1α, IL-1β, IL-1Ra, Tumor Necrotizing Factor (TNF)-α ...
Total bilirubin is determined here with a multipoint calibration approach and with use of Standard Reference Material No. 916 bilirubin from the National Bureau of Standards. The bilirubin calibration solutions prepared in solutions of Cohn Fraction V human albumin were stable for at least one year when stored at -80 degrees C. Studies for direct bilirubin analysis show that the serum sample sh...
A simple reproducible method for the ultramicro determination of total and direct serum bilirubin is presented. This method provides a greater sensitivity than that obtained with other colorimetric ultramicro procedures. Total bilirubin values agree with those obtained with the macro Malloy-Evelyn procedure, but direct-reading bilirubin values were significantly higher with the presented method.
