Just an update.
My Neurologist wasn't able to come up with any more test results than I already had.
There was no record of, homocysteine and methylmalonic acid levels having been taken.
I have an appointement with my GP in 2 days to arrange getting this measured & also to get more precise B12 figures.
I will discuss with him the relevance of getting any other tests redone to obtain more precise results.
I had started taking B12 supplement last week but have stopped now in case it may influence any further test results.
