RENAL STONE PROFILE, BLOOD AND URINE
Stone Profile - Stone Profile, Renal
Serum or Plasma: Glucose, Calcium, Phosphorus, BUN, Sodium, Potassium, Creatinine, Chloride, Albumin, Uric Acid, Cholesterol, Total CO2
Timed Urines: Urine Calcium, Urine Uric Acid, Urine Magnesium, Urine Creatinine Clearance, Urine Urea Nitrogen, Urine Oxalate, Urine Citrate, Urine Sodium, Urine Calcium/Creatinine excretion ratio
Specimen Collection Requirements
Patient should avoid ingestion of vitamin C prior to collection (Oxalate).
Both urine and serum or plasma are required.
Serum or Plasma: Allow serum to clot completely at room temperature (minimum: 30 minutes). Preferably, separate serum or plasma from cells before transport.
Timed Urine: Refrigerate urine specimen during collection. To properly aliquot sample: 1) Thoroughly mix entire urine collection in one container; 2) Remove 20.0-30.0 mL aliquot. Record total volume of 12 or 24 hour urine, urine collection time interval, patient’s height and weight on container and test request form.
Serum or Plasma: 1.0 mL, Urine: 20.0 mL
Serum or Plasma: 0.5 mL (Whole Blood 1.2 mL minimum draw), Urine: 3.0 mL
Grossly hemolyzed specimens, urine specimens exposed to ambient temperature (20-25°C) for greater than 4 hours
Serum or Plasma: Lithium heparin tubes (PST) are stable up to 3 days refrigerated on the primary spun gel tube. AFTER SEPARATION FROM CELLS: Ambient (20-25°C): 24 hours; Refrigerated (2-8°C): 3 days; Frozen (at or below -20°C): 1 month
Urine (unpreserved): Ambient (20-25°C): 4 hours; Refrigerated (2-8°C): 6 days; Frozen (at or below -20°C): 1 month
The blood specimen for Creatinine Clearance must be collected within 48 hours of the initiation of the timed urine collection or within 24 hours of the end of the collection period unless the patient’s physiologic condition changes significantly.
LEGACY: 7 days/week, Urine Oxalate (ARUP): Mon - Fri, Urine Citrate (ARUP): 7 days/week
LEGACY: 24 hours ARUP: 1-4 days
ARUP: Urine Oxalate (20482), Urine Citrate (20852)
Corrected Creatinine Clearance reported based on patient body surface area, age and gender. Interpretive guidelines for other urine chemistries provided with report.
Legacy Referral Departmen will adjust the pH to 1.5-2 with 6M HCl for ARUP Labs (Urine Oxalate and Urine Citrate). Send urine refrigerated.
Creatinine Clearance: 82575, U Calcium: 82340, U Citric Acid: 82507, U Creatinine: 82570, U Magnesium: 83735, U Oxalate: 83945, U Sodium: 84300, U Urea: 84540, U Uric Acic: 84560, Renal Function: 80069
