I have a strong family history of PA and what I suspect are symptoms but as my results are low but in range the doctors have refused to treat me. I have supplemented with B12 sublingually for the last 9 months but I am still symptomatic.
I am considering paying for the active B12 test privately but wanted to know if it's worth me doing as I have been supplementing? Will the results be skewed because of this, making them worthless?
Many thanks in advance for any advice anyone can give.
