My husband was told that his lambda light chain #'s were off, he went to a physician and said dr. advised him that he would not treat for anything because the numbers were not that bad-it is all relative to the person. My question is, what type of doctor did he see-we can't remember and when do you know there is a problem. My husband has been ill will various things for over six years, it is hard to tell what is causing these problems. thanks
