Urine Collection Procedure



Collection Instructions

Specimen:Timed collection (24 hours), or random
Optimal Volume:Submit entire collection; analysis requires 1 mL
Container:3 L plastic jug (Plastic leakproof container, sterile)
Collection Instructions:Specimen should be refrigerated during collection. ARUP studies indicate that refrigeration of urine alone, during and after collection preserves specimens adequately if testing within 14 days of collection.
Patient Preparation:Diet, medication and nutritional supplements may introduce interfering substances. Patients should be encouraged to discontinue nutritional supplements, vitamins, minerals and non-essential over-the-counter medications (upon the advice of their physician). High concentrations of iodine may interfere with elemental testing. Abstinence from iodine-containing medications or contrast agents for at least 1 month prior to collecting specimens for elemental testing is recommended.
Causes for Rejection:Urine collected within 48 hours after administration of a gadolinium (Gd) containing contrast media (may occur with MRI studies), acid preserved urine, samples not aliquoted into ARUP metal-free plastic vials.


Processing and Shipping

Specimen Processing:Mix collection well before aliquot is taken. Aliquot 8 mL, 1 mL minimum into 2 ARUP blue top metal free plastic vials. Regular aliquot tubes will be rejected. Store in refrigerator. Record total volume and collection time interval on transport tube and on request form.
Shipping Instructions:Ship at refrigerated temperature.
Stability:1 week at room temperature; 2 weeks refrigerated; 1 year frozen.
