Monoclonal Protein Study, Expanded Panel, Serum

Useful For Suggests clinical disorders or settings where the test may be helpful

Diagnosis of monoclonal gammopathies


Eliminating the need for urine monoclonal studies as a part of initial diagnostic studies (ie, rule-out monoclonal gammopathy)


Assessing risk of progression from monoclonal gammopathy of undetermined significance to multiple myeloma

Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.
