Test Details
Methodology
Agarose gel immunofixation electrophoresis (IFE)
Result Turnaround Time
3 - 5 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

Detect and identify monoclonal immunoglobulin gammopathies
Special Instructions

Custom Additional Information
Immunofixation electrophoresis of serum or urine is most often ordered to evaluate a monoclonal globulin detected in a protein electrophoresis or to delineate a possible lymphoproliferative process, particularly myeloma. This procedure will help identify the specific light and heavy chain components of a monoclonal protein.
