title: [Results of multicenter determination of preliminary reference values for beta-N-acetylglucosaminidase in urine of adults].
abstract: Reference intervals for beta-N-acetylglucosaminidase (beta-NAG) using the method with chlorophenol red-N-acetylglucosaminide (CPR-NAG) as substrate were evaluated in second morning urine samples of 358 adults, combined from 4 laboratories of 3 countries. As upper reference limits for 37 degrees C measuring temperature are proposed: 5 U/l or 4 U/g creatinine respectively.
