Oxalate Urine Test, Quantitative, 24-Hour
That Oxalate Urine Test looks for the presence of certain toxic substances in the intestinal tract.
Description
Type: Urine
Patients who form calcium oxalate kidney stones appear to absorb and excrete a higher portion of dietary oxalate in urine than do normals. Hyperoxaluria is not uncommon in subjects with malabsorption. Twenty-four hour urine collections for oxalate are indicated in patients with surgical loss of distal small intestine, especially those with Crohn's disease.
