Went for my GP app last night. To be fair she was very nice, listened to me and spent over half hr with me. She is writing a referral note for Active B12 test that I can best obtain at a private hospital, as they will draw the blood too and use their own labs - result with GP in 2 days approx turn around.
My GP is however skeptical that it is B12 causing my nerve damage symproms as although my levels are in the grey area and she recognises are only there because I supplement, She feels my full blood count would show as all in normal range except MCHC which is just below normal range which indicates small red blood cells not the expected large red blood cells. She said a heamatologist would not be impressed with issues as they look at the full blood count.
She had looked at NICE guidelines and only absorbed the issue re pregnant women.
So we agreed to leave it to see what the active B12 test shows. She said she would test for intrinsic factor but didn't see necessary really as obviously absorbing as this is why the B12 increased with supplementation. She said intrinsic factor was only about absorption - is this correct?
She also said that in any serum total B12 test it is expected that at anyone time only 20% of the B12 will be active - this is normal. If the active B12 shows 20% of total when tested therefore then this is normal function
Does anyone have any comments to help - thanks
Oh I suppose I will have to phone the lab to see how soon after supplementing will the test be viable.
Not sure if it is worth it financially and re the stress and not being able to supplement. Maybe considering my full blood count results and GP's comments, I should just vigilantly supplement well with a full B complex containing high B12? (instead of half heartedly as previously) I have also started taking colostrum as good for nerve damage apparently.
After my blood tests which I am relying on in November, I started supplementing with a phytoplankto to provide a full range of minerals. The product states: provides B12 but as far as I am aware plant B12 sources are actually antagonistic to B12 that we need. Maybe taking the phytoplankton without the usual B vit complex (which is what happened) may have reduced my B12 activity hence the symptoms starting? Clutching at straws here.
