Table 3 Urinary purine metabolite analytes measured from 24-h urine collections analysed by the capillary electrophoresis method

From: Evaluation of dogs with genetic hyperuricosuria and urate urolithiasis consuming a purine restricted diet: a pilot study

  1. Metabolites are reported as both concentrations (conc; in mg/L) and excretions (exc; in mg/24 h), and urine volume is expressed in mL/24 h. Data are presented as the least square means ± standard error. P values result from the contrast method comparing baseline visit to visits 2 and 4 together. UA = uric acid, HX = hypoxanthine, X = xanthine, ALL = allantoin
