Answer

Depending on the 24-hour urine uric acid levels before the purine-restricted diet and after the purine-restricted diet, patients who are hyperuricemic can be categorized into the following three groups:

  • High-purine intake - Prediet value greater than 6 mmol/d, postdiet value less than 4 mmol/d
  • Overproducers - Prediet value greater than 6 mmol/d, postdiet value greater than 4.5 mmol/d
  • Underexcretors - Prediet value less than 6 mmol/d, postdiet value less than 2 mmol/d
