Hi Joe, you will need a bone marrow biopsy and a full work up to confirm myeloma. They recommend we see a myeloma specialist from the start.

Does a high IgA level with low IgG and IgM indicate IgA myeloma and a more aggressive condition?
Your elevated IgA level combined with low IgG and IgM could suggest IgA myeloma, but your doctor will need additional tests to confirm this. The pattern you're describing—one antibody type being very high while others are low—is common in myeloma.
IgA myeloma does tend to be more aggressive than other types. Here's what research shows:
- It grows faster and spreads more easily
- It has higher relapse rates after treatment
- It's more often linked to genetic changes that make cancer harder to treat
- It's more likely to form tumors outside the bone marrow (extramedullary plasmacytomas)
- It can be harder to track on standard blood tests
About 1 in 5 people with myeloma have the IgA type, making it the second most common form after IgG. Your doctor will likely use tests like immunofixation electrophoresis (IFE) to confirm your myeloma subtype and may track your M protein levels over time. Since IgA myeloma can be more aggressive, this information could influence when your oncology team recommends starting treatment.
Given that you're weighing different treatment timing recommendations, it's worth discussing with your doctors how your specific IgA level and any other test results (like genetic markers or staging information) factor into their recommendations. The aggressiveness of IgA myeloma is one consideration, but your complete clinical picture matters most.
