Specimen Required
Patient Preparation
24-hour urine. Refrigerate during collection.  
Specimen Preparation
Transfer 4 mL aliquot from a well-mixed 24-hour urine collection to an ARUP Standard Transport Tube or ARUP supply #48098 (ARUP Standard Transport Tube with 20 mg Sulfamic Acid) (Min: 3 mL). Record total volume and collection time interval on transport tube and test request form. Adequate refrigeration is the most important aspect of specimen preservation. Preservation can be enhanced by adjusting the pH to 2-4 by addition of 6 mol/L HCl or by using ARUP supply #48098, available online through e Supply using ARUP Connect or by contacting ARUP Client Services at (800) 522-2787.
Note: use caution when adjusting with 6 mol/L HCl as a pH of less than 2 will decrease analyte stability.
