This research aims to characterize MGUS subtypes and evaluate demographic and laboratory differences, emphasizing IgM MGUS.
Retrospective review of MGUS cases diagnosed from 2019 to 2025 at a single institution.
Included patients underwent standardized workup including complete blood count, serum protein electrophoresis, and immunofixation.
Data on age, sex, race, and peak laboratory values were collected.
IgG MGUS was most prevalent at 59%, followed by IgM at 30% and IgA at 11%.
Median follow-up was 2.1 years, with no reported progression to hematologic malignancy.
Significant demographic variations among subtypes, particularly in racial distribution and female predominance in IgM.
