I have my blood work results from my recent lab tests . Quantitative immunoglobulins, Vitamin B6, Vitamin E , protien electrophoresis and zinc were normal, copper was high ..

My previous blood tests including CBC, fasting glucose, B12 , thyroid etc were also normal.

Does anyone know the consequences of high serum copper? Does it have any relation to PN?

Copper toxicity can be neurologically problematic although a bit rare. Usually copper toxicity exhibits neurological issues like dystonia and tremor. These symptoms don't seem to be the symptoms that you are having.

Copper deficiency symptoms are more like the symptoms that you have but you have high copper levels not low.

Just out of curiousity, how high was your copper? Normally, our bodies dump extra copper pretty well so maybe the copper issues point to some other underlying issue that could be related to the neuropathy. Did your doctor have any opinions regarding your bloodwork or did you get an idiopathic diagnosis?

So far no diagnosis. Wating for an MRI in October. Copper was marginally high at 23.8 at umol/L (should be below 22).. My sugar (although "normal" as per the doctor) seems to be in the pre diabetic range (fasting 102 mg/dl and 160-170 mg/dl 2 hours post prandial) . That , alongwith my allopurinol medication for gout are my prime suspects at the moment
