--given the lack of positive results from the other bloodwork, is going to be the glucose tolerance test, which may diagnose a "pre-diabetic" impaired glucose tolerance or insulin resistance that may well lhave something to do with the neuropathy symptoms. Given Alan's general state of health, I would be surprised if the other immunglobulin tests show a monoclonal result.

Thing is, as Brian has mentioned, if there is a glucose component to this, Alan may have improved his condition, or at least arrested any further deterioration, by exercising, eating better, and losing weight. (And he should remember to thank you, Mel, for much of that.)
