Additional information Total Protein is automatically included in test request. Most monoclonal cryoglobulins are detected by serum electrophoresis, but if cryoglobulins are suspected and the PEP is normal, order Cryoglobulin, Quantitative. Most monoclonal proteins are also detected by electrophoresis, but if negative in a patient with a high suspicion of a monoclonal gammopathy it may be detectable by immunoelectrophoresis.

An interpretation of this test by a laboratory physician will automatically be performed and billed for separately.
