ABSTRACT
Objective:
To investigate the interfering factors in the determination of creatinine(Cr) using the American Clinical Laboratory Standards Association (CLSI) EP7-A3 document.Methods:
According to the CLSI EP7-A3 document, fresh serum (no hemolysis, lipemia, and jaundice) was used on the day of the experiment and confirmed the interfering substances through the pairing difference experiment and the point-to-point analysis method was used in the dose effect experiment to clarify the difference of interfering substances.Results:
Triglyceride (16.94 mmol/L), dobutamine hydrochloride (4.01 μmol/L), ascorbic acid (298 μmol/L) did not interfere with the determination of Cr. Free bilirubin (684 μmol/L), conjugated bilirubin (684 μmol/L), calcium hydroxybenzene sulfonate (144 μmol/L) and hemoglobin (10 g/L) were used as the maximum concentrations of interferences for the dose effect test, the results showed that the above interferences had negative interference on the determination of Cr.Conclusion:
According to EP7-A3, it is valuable to evaluate the interference factors of creatinine determination.
