Hello, I started on the b12 injections around January (? memory shocking!) and still not feeling there has been a great improvement with all my symptoms, tiredness in particular.My test result for B12 was 236 (previous test was lower but nothing was done because I was still within range - had to almost beg for something to get done). As well as my symptoms, I did test positve for having gastric paretial cell antibodies and I had raised MCV - 102. The most recent b12 test came back at 630 and am worried now that my GP will stop the jags because I was just "on trial.". I had the Vitamin D test which came back at 36 and the Calcium test which came back just below normal (?) so my GP put me on Accrete D3. I was retested for the calcium at the same time as the B12 and it has now come back at -207. I'm seeing my GP on Thursday to discuss the results and would appreciate any comments.
