I cannot find which tests to have and where to order them from - to check active B12.
I supplement and inject 'sometimes' (cyno and B complex) - cannot do IM myself and so have to rely on when I can get someone (friend / family) to do it for me - but consequently my 'serum' b12 is always high.
I have had odd blood tests for a while - high RBC,, high Haemaglobin and haematocrit. One test was within the normal ranges and I think that this was when I was having regular injections - but then the RBC width was large.
Does any if this make sense to anyone.
