Copper deficiency??

I am still in limbo and watch and wait process of possible diagnosis of MS. I have been to my neuro 3 times in the last yr & half with my symptoms. I had a full brain and spine MRI done. According to neuro this showed prolapsed discs in cervical and thoratic area of spine…tonnes of bloods done for autoimmune issues, lupus etc. Nothing remarkable, just b12 was high. So today at my third appointment he has suggested Copper deficiency?? and I have had a blood test done for this. Has anyone else been tested for copper deficiency during their diagnosis process?? Thanks RR25
