Urine Collection Procedure

Collection Instructions

Specimen:Urine, a first morning void is preferred
Optimal Volume:Submit entire collection.
Container:Plastic leakproof container, sterile

Processing and Shipping

Specimen Processing:Do not aliquot. Submit entire collection; analysis requires 20 mL, 10 mL minimum. Store in refrigerator.
Shipping Instructions:Ship at refrigerated temperature.
Stability:Specimen can be frozen once.
Test Performed at or Referral Lab Protein  (UMMC-East Bank)


Use:This combination of tests should be requested when the physician seeing the patient would like an immunofixation automatically performed on the same urine specimen to characterize a suspected monoclonal protein that has been seen on urine protein electrophoresis. As an example, for anyone in whom there may be a clinical suspicion of multiple myeloma, we suggest a protein electrophoresis with automatic reflex to immunofixation be ordered.
