to investigate the possibility of measuring urinary oxalate output instead of faecal fat excretion as an outpatient screening test for steatorrhoea , we determined 24 hour urinary oxalate and five day faecal fat excretion before and during an oral load of sodium oxalate 600 mg daily ( oxalate 4.44 mmol ) , in 32 patients with suspected malabsorption on a diet containing oxalate 30 mg ( 0.33 mmol ) , fat 50 g ( 180 mmol ) , and calcium 1 g ( 25 mmol ) .
