Based on the search results provided, while MGUS and multiple myeloma both involve abnormal plasma cells and M protein production, the specific numeric diagnostic criteria that differentiate them are not included in the given excerpts.
What we do know is that MGUS involves "much lower levels" of abnormal plasma cells and M protein compared to multiple myeloma. In MGUS, these levels are typically not high enough to cause organ damage or symptoms.
For a more precise answer with specific numeric thresholds, it would be best to consult with your hematologist who can provide the exact diagnostic criteria they use to differentiate between these conditions.
