Test Overview
See individual tests
To accurately follow known cryoglobulin monoclonal gammopathy patients. To follow, identify and type monoclonal immunoglobulins for heavy and light chain specificity. Monoclonal gammopathy evaluation (MGE) is essential when clinical, hematologic, or pathologic findings indicate: multiple myeloma, Waldenstrom;s, heavy chain disease, amyloidosis, or immunoglobulin deposition disease. MGE is also essential in the presence of abnormal bands on serum protein electrophoresis (TPE), in cryoglobulins, in Bence Jones proteinuria, in pyroglobulins, and in hyperviscosity syndrome.
Test includes serum protein electrophoresis, total protein, immunoglobulin quantitation (IgG, IgA, IgM), and serum free light chains.
Pathologist interpretation of results provided. See individual test reference ranges.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

72 hours
Specimen Requirements
Whole blood must be maintained at 37 degrees C +/- 2 degrees from the time it is collected until serum is separated from the cells. Collect blood in pre-warmed red top tube (serum separator is unacceptable). Immediately place the specimen into a 37 degrees +/- 2 C incubator or water bath. Leave at 37 degrees C until the clot retracts, remove serum from clot, centrifuge at room temperature, and aliquot cell free serum into plastic aliquot tube. Please note on the specimen label that the specimen was processed at 37 degrees C. Keep serum at room temperature until delivered to MLabs. If specimen processing equipment is not available, the patient should have the specimen collected at a Michigan Medicine Taubman Center Blood Draw Station.
Place specimen in 37 degrees C Thermos containing a warm pack or waterbath immediately. See Collection Instructions below.
Additional Information
