Abstract
Background: 24-h urine measurements are used in the routine diagnosis and follow-up of many diseases in the clinical laboratory. Calcium (Ca(2+)), magnesium (Mg(2+) phosphate PO(4)(3-)) and uric acid are frequently requested markers in 24-h urine samples. Because of the different solubilities of these parameters, different urine collection conditions - urine in base for uric acid and urine in acid for Ca(2+), PO(4)(3-) and Mg(2+) measurements - are recommended.
