Thank you for the great information! I am not worried about MM, maybe b/c my kappa FLCs are not dramatically high. I am curious, though, on its association with MS. I have heard that it may be another way to test if O-bands are not found. This is similar to that?? Not sure. Anyway, I'll be back to let everyone know.

Again, thank you & if I do have MGUS, onward I go!
