Hello, this is Dr. David. I have read your question and am ready to help.
multiple myeloma is rare in young people, globulin is a generic blood protein and a specific M blood protein is elevated in multiple myeloma patients.
I would agree with testing her for SLE and even checking for a gluten allergy in her bowels.
as well as a thyroid level.
the serum protein electrophoresis will tell if she has a M spike or any spike at all.
good luck to her and you.
let me know if you have any questions
