In the course of one year, two patients were encountered with incidental serum uric acid values of 0.2 and 0.3 mg per 100 ml. Hypouricemia may be more prevalent than would be suggested by the small number of previously reported cases. Urinary uric acid determinations provide a simple means of evaluating the causes of hypouricemia in such patients.
