Immunofixation Serum interpretation

I have two lab result in which I got the same response. My Doc is contemplating sending me to an oncologist and so here is what my result reads.

"A poorly defined area of restricted protein mobility is detected and is reactive with IgM and labda antisera."
Also have B12 is 2000H extremely high
Immunoglobulin A is 22L which is extrememly low.
Also RDW is 19H
Does anyone have any clues here what this all means?

Thank a million
Teri
