Specimen Type
UrineOrdering Guidance
The use of a random urine specimen is sufficient for identifying the presence or absence of a monoclonal immunoglobulin, but a 24-hour specimen is preferred for quantitating and monitoring the abnormality. See MPSU / Monoclonal Protein Study, 24 Hour, Urine.
Shipping Instructions
Refrigerate specimen during collection and send refrigerated.
