What do elevated kappa light chains and IgM indicate?

Question

Hi doctor,

I am a 34 year old male. My free kappa light chains are elevated, but the ratio came back normal. IgM is also elevated, but IgG and IgA are normal. What does this mean? I do have a history of DVT. I am on blood thinners. I also did angiograms of my lower extremities. Can you help me understand what is actually going on? Please find the attached reports.

Hi,

Welcome to icliniq.com.

I have seen the reports (attachment removed to protect patient identity).

IgM and kappa can be raised in any acute infection.

Mixed infection probably started with viral and superadded bacterial infection. Repeat all blood tests after three months for evaluation. Start on a broad spectrum antibiotic for 7 to 14 days. There is nothing to worry, it is only a normal variant.

Thank you.
