Specimen : Urine (24-hour)
This test measures how much calcium your body is excreting over 24 hours, adjusted for kidney function (creatinine). It helps identify abnormal calcium handling, which can indicate kidney stones risk, bone metabolism issues, or certain hormonal imbalances.
Relevant to athletes because intense training and high sweat losses can alter calcium excretion patterns, and chronic dehydration or excessive salt intake may increase stone-forming risk. Also useful if monitoring bone health during heavy training cycles, as persistently elevated urinary calcium can signal inadequate dietary intake or excessive loss despite calcium supplementation.
