We analyzed the urinary excretion of glucose and N ‐acetyl‐β‐ D ‐glucosaminidase ( NAG ) in six okapis ( O kapia johnstoni ) in captivity to investigate the cause of their urinary sugar excretion. The urinary glucose‐positive okapi had significantly higher urinary NAG indices than the urinary glucose‐negative okapi. There was also a positive correlation between urinary glucose levels and urinary NAG indices. These results suggest that the proximal tubular function of the glycosuric okapi may have been obstructed, which impaired glucose reabsorption.
