Performance of different screening methods for the determination of urinary glycosaminoclycans.

Background: The study aim was to compare the performance of three different methods used for determining urinary glycosaminoglycans (GAG) levels in spot and 24-h urine samples.

Methods: Performance characteristics were studied for cetylpyridinium chloride (CPC), and manual and automated dimethylmethylene blue (DMB) methods.

Results: For automated DMB method, within-run precisions were 9.
