24 HRS URINE-CITRATE, in Visit Clinic

High citrate in a 24‑hour urine (hypercitraturia) means your citrate excretion is above the laboratory’s reference range. It commonly reflects high dietary citrus/alkali intake or alkali medications (e.g., potassium citrate) and metabolic alkalosis. It is usually protective—citrate binds calcium and lowers kidney‑stone risk. Persistently elevated values should prompt review of diet, supplements, and acid–base status with your clinician.

A 24-hour urine test measures total urine volume and concentrations of substances excreted over a day to evaluate kidney function and metabolic status. Common measurements include creatinine or creatinine clearance, protein (albumin), electrolytes (sodium, potassium), calcium, oxalate, uric acid, hormones and metabolites (e.g., cortisol, catecholamines), and drug levels. Results help diagnose kidney disease, electrolyte or metabolic disorders, stone risk, and monitor treatment.

A 24‑hour urine citric acid test measures citrate excreted in urine collected over a full day. It assesses metabolic risk for kidney stones—low urinary citrate (hypocitraturia) promotes calcium stone formation—and helps guide treatment and dietary advice. Proper collection requires saving all urine for 24 hours, often refrigerating the container, and avoiding certain medications or dietary changes beforehand per clinician instructions.

A 24‑hour urine copper (Cu) test measures total copper excreted in urine collected over a full day. It evaluates copper metabolism—commonly used to help diagnose Wilson disease and monitor chelation therapy. Collection involves saving every urine pass into a clean, often metal‑free container for 24 hours as instructed, avoiding contamination, and returning the sample promptly for laboratory analysis.

High urinary citrate generally indicates a reduced risk of calcium kidney stone formation because citrate binds calcium and inhibits crystal formation. Causes include diets rich in fruits and vegetables, alkali therapy (bicarbonate or citrate supplements), or metabolic alkalosis. Elevated blood citrate is uncommon but can occur with citrate infusions/anticoagulation or metabolic disorders affecting the citric acid cycle; clinical context guides interpretation.

Citrate (usually as potassium citrate) can help prevent and sometimes dissolve certain kidney stones. It raises urinary citrate, which binds calcium and reduces crystal formation, and alkalinizes urine—useful for dissolving uric acid stones and lowering calcium oxalate risk. It’s a medical treatment, not a universal cure; effectiveness depends on stone type and should be used under medical supervision due to dosing and electrolyte risks.
