Monoclonal gammopathies are characterized by the secretion of a monoclonal protein or M-protein. A wide variety of conditions can produce an M-protein, and the initial screening and monitoring of these patients require an array of tests. Herein we described best practices for protein electrophoresis ordering at Corewell Health.

The test Pathologist Review Peripheral Smear [LAB7550] will become a lab only orderable in the near future. Effective, Monday, May 1, 2023, all provider ordered pathology smear reviews on outpatients will be cancelled by the hematopathologist. If a pathologist interpretation of the blood smear is still desired, please order a Pathology Consult [LAB1230850], ask for a “general pathology consult” and indicate your question for the pathologist who will be interpreting the blood.
For Corewell Health West Epic Providers (Epic Hyperspace, Epic Community Connect and Epic Care Link) a tip sheet is available for ordering in Epic. If you cannot access the tip sheet or have further questions, please use the contact us link above.

This winter, West Michigan influenza infections peaked in December 2022 and significantly declined throughout February and March 2023. Now with a low prevalence of circulating influenza, using the most sensitive diagnostic test is recommended in order to obtain accurate and actionable results. Influenza antigen testing (e.g. Sofia instrument) is no longer appropriate at this time and Influenza PCR testing should be ordered when clinically indicated.
General Information
Peripheral Smear Interpretation for CBCs performed outside of Corewell Health Laboratories
Please note that there will be a change in the format of pathologist review of outside peripheral blood smear slides that are not from CBCs performed at Corewell Health (formerly Spectrum Health) laboratory facilities. The peripheral smear interpretation will now be found in the anatomic pathology portion of the medical record under an outside consult heading (SO prefix) instead of in the laboratory section near the CBC indices.
This change may result in a different format for your results to be viewed. It may change the type and amount of bill your patients may receive.
