Bilirubin interference in kinetic creatinine determination.
194 CLINICAL CHEMISTRY, Vol. 25, No. 1, 1979 gas chromatography before and after acid (6 mol/L HC1) and alkaline (NaOH) hydrolysis. We frequently observe a peak in the lactic acid position after alkaline hydrolysis. After acid hydrolysis of the same urine no lactate isobserved, but a peak appears in the position of levulinic acid. The mass spectra of these two peaks were identical with those of...
متن کاملInterference by glycolic acid in the Beckman synchron method for lactate: a useful clue for unsuspected ethylene glycol intoxication.
noassay methods, which produce a variable bias compared with a selective technique, require careful scrutiny at sample time points other than the traditional predose (trough) measurement. As shown above, and from interlaboratory comparisons (11 ), there is ample evidence demonstrating differences between analytical techniques for trough CsA concentration measurements, but these differences need...
متن کاملXanthine interference in the Kodak "Ektachem" determination of uric acid.
In connection with studiesrelated to the purines in serum of leukemia patients (1), xanthine interference was observed in the Kodak Ektachem enzymically based determination of uric acid, leading to significant underestimation of the latter’s actual concentration-a finding that agrees with a previous report (2). In hereditary xanthinuria, total oxypurine concentrations in serum ranged from 1 to ...
متن کاملEvaluation of the Beckman creatinine analyzer.
We compared results obtained with the Beckman Creatinine Analyzer (Beckman Instruments, Inc.) to those with the GEMSAEC Centrifugal Analyzer (Electro-Nucleonics, Inc.) and with a manual method for determination of creatinine in serum and urine. Linearity, stability, recovery, and precision were evaluated. Interference from bilirubin, protein, lipemia, uric acid, and hemolysis is negligible, but...
متن کاملRelation between creatinine and uric acid excretion.
The relation between creatinine and uric acid metabolism was analysed in 77 male patients with primary gout and 62 healthy male subjects. Significant positive correlations between 24 hour urinary creatinine and uric acid excretion were shown in both groups. The mean urinary creatinine and uric acid excretions in the patients with gout were significantly increased as compared with those of norma...
