Hi everyone. I was diagnosed with B12 deficiency & macrocytosis and had loading doses of Hydroxocobalamin. I now have 2 monthly injections but find it's not enough, but can't get my GP to take it seriously enough! My bloods are as follows: Serum B12 (189 - 883) was <83 now 928, Serum Folate (4.8 - 19) was 15.3 now 9.1, Serum Ferritin (22 - 275) is 35, RBC (4.5 - 6) was 4.01 now 4.78, WBC (4 - 11) was 4.4 now 8.5, MCV (80 - 100) was 11.7 now 99.4, MCH (27 - 32) was 37.4 now 32.4, IFA is Neg, PCA is Pos. Apparently if IFA is Neg, it's not PA, but what about the PCA being Pos? Also, I think my Folate and Ferritin should be higher and the MCV and MCH should be lower. What do you all think? Many thanks.
