Use of a Standard Urine Assay for Measuring the Phosphate Content of Beverages

Hyperphosphatemia is strongly associated with cardiovascular morbidity and mortality in patients with chronic kidney disease. Phosphate in beverages is readily absorbed and could have a significant impact on serum phosphate levels. Patients are routinely warned about the phosphoric acid in colas, but information on the phosphate content of other beverages is difficult to find. We have shown that the phosphomolybdate method, which is used in the vast majority of hospital laboratories for measuring phosphate in urine, can give an accurate measurement of the phosphate content of beer, cider, wine, and soft drinks.
