I’m still awaiting biopsy results from an endoscopy in December. The report found atrophic gastritis. Subsequent B12 tests came back at 225ng/L and folate at 1.5. The limits in my area for B12 are 200 to 900.
My GP prescribed me 5mg folate. This was 2 week ago. I’ve also started eating better consuming veg and fish every day.
I had an appointment today with my GP and I took the current NICE guidelines on B12 and highlighted the relevant parts. My GP said my levels were normal. I argued this and pointed out that my B12 has dropped from 495 in 2023 to 225 now. I also pointed out that the serum test isn’t accurate so my levels could be lower. I also pointed out that I do have neurological symptoms such as pins and needles and according to the NICE guidelines that puts me at intermediate risk with the need for futher tests and it does actually suggest to commence with B12 injections.
My GP for some reason cannot give the MMA blood test or active B12. However, he did agree to give me the IFAB test and the parietal cell antibody test. He also retested my serum B12 and folate.
I’ve just had a text saying my B12 is now 429 and my folate is now normal at 24 which is on the high side now.
I’m a bit baffled as to what to think now. The endoscopy report stated atrophic gastritis with negative pylori so surely I must have autoimmune gastritis which essentially is PA? Any advice would be welcomed
