I am 30 weeks pregnant. I am on monthly B12 injections, vitamin D pills and have had two iron infusions in the last couple of months. However, my most recent blood work (3 weeks ago) came back still showing anemia (and I am feeling pretty grotty too):
Haemaglobin: 118 (range 120-150)
RBC Count: 3.74 (range 3.8-4.8)
White cell count: 11.35 (range 4-11)
MCHC: 311 (range 315-345)
MCH: 31.6 (range 27-32)
Transferrin Sat Index: 32% (range 16-50)
Serum Ferritin: 378 (range 10-200)
I am assuming my iron levels are now OK following the transfusions, but am wondering about more frequent B12 injections. The consultant wants me to repeat my bloods this week (including iron work, FBC, folate, Vit D and B12), and despite me saying that my B12 level will be high (it's been >2000 since starting monthly injections) they insist on testing it still, and no doubt will tell me that I don't need them so frequently.
I am wondering whether I should try and convince them to test either MMA and / or Homocysteine levels?
Am I right in thinking that even if you have high B12 levels, you can still have a deficiency at the cellular level ("functional B12 deficiency") and that this would be picked up by raised MMA and homocysteine levels?
If this is the case, can anyone point me towards some 'official' documentation which states that, so I can show the Doctors and try to persuade them to do those tests as well?
Thanks for the advice.
