Immunofixation, Serum

CPT Code(s):

82784(x3), 86334

Methodology:

Electrophoresis followed by immunodiffusion against monospecific antisera to immunoglobulin and individual heavy and light chain (IFE); turbidimetric quantitation of IgA, IgG, and IgM

Performed:

Monday - Friday

Reported:

-

Use:

This test detects and identifies monoclonal immunoglobulin gammopathies.

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 characterize the specific light and heavy chain components of a monoclonal protein.

Specimen Requirements:

Type: Serum (Sperate serum from red cells.)

Container/Tube: Red-top tube or gel-barrier tube

Sample Volume: 2 mL

Minimum Volume: 1 mL

Storage: Store specimens at room temperature.

Stability (collection to time of analysis/testing):

  • Ambient: 14 days
  • Refrigerated: 14 days
  • Frozen: 14 days
  • Freeze/Thaw cycles: Stable (x3)
Causes for Rejection:

  • Gross hemolysis
  • Gross lipemia
Note: The patient's age and clinical diagnosis must be submitted with the test request.

Collection Procedure:

-

Reference Values:

Normal pattern
