[Results of the multicenter evaluation of a new test for measuring beta-N-acetylglucosaminidase in urine].

Abstract

We report on the results of a multicentric evaluation of a new kinetic method for the determination of beta-N-acetylglucosaminidase. Main topics of investigation were imprecision, recovery in controls with interlaboratory survey, measuring range, calibration stability, method comparisons using native urine and interferences. Distinct advantages in practicability and interlaboratory transferability compared to the introduced methods were observed. The new method fulfills the conditions to be adapted as routine method in the quantitative photometric analysis of urine.
