Why is the Test Performed?
Urine volume is normally measured as a part of the creatinine clearance test or any test that measures the amount of a substance eliminated in a day (for example, protein, aldosterone, sodium, potassium, urea nitrogen). It is also measured in patients with polyuria (abnormally large volumes of urine), such as, diabetes insipidus.
