The Beckman Creatinine Analyzer 2 was evaluated. This new instrument determines creatinine by a Jaffe rate method and utilizes an optical detection system which measures the rate of change in absorbance at 520 nm 25.6 s after samples introduction. The linearity of the instrument was verified up to creatinine concentrations of 24 mg/dl. Recovery averaged 92% from serum and 97% from urine. Comparison studies using serum specimens were made against a manual, non-kinetic Jaffe method and a Technicon SMA 12/60. Urine comparisons were made against the manual method. All comparisons indicated the Beckman analyzer yields lower creatinine values due to the minimization of interferences from non-creatinine chromogens. No significant change in these correlations was observed with elevated bilirubin concentrations (greater than 10 mg/dl) or with lipemic specimens (triglycerides up to 3390 mg/dl). Within-day and day-to-day precision were within the stated manufacturer''s specifications for sera and urine specimens.
