The Kidney Stone 24-Hour Urine Test. What’s Causing My Kidney Stones?
The Kidney Stone Formation Risk Panel, 24-Hour Urine Test is a comprehensive evaluation designed to uncover the reason for kidney stones and the risk of forming stones in the future. This test measures various compounds in your urine that can contribute to kidney stone formation, including calcium, oxalate crystals, uric acid, and citrate levels, among others.
Why This Test Matters In Kidney Stone Disease.
Identifying the risk factors for kidney stone formation is crucial. It allows for the implementation of personalized prevention strategies to minimize the risk of future kidney stone formation. Understanding these risk factors can lead to dietary adjustments, lifestyle changes, and sometimes medication to help prevent new stones from forming. Ordering the Kidney Stone Urine Test can provide valuable insights into your urinary chemistry, guiding targeted interventions to reduce your risk of kidney disease.
