Blood tests have come back with B12/folate level at 4.9 & serum at 1936 ng/L. Dr says all results are fine and I obviously do NOT have a deficiency. Despite my careful explanations AGAIN of how my body might not be using the B12 because it cant get hold of it from my blood he thought that was ridiculous.Discussions ensued, I asked if he would refer me for an MMA test ( methylmolonic acid test) he said he had never heard of it and wouldnt ask for a blood test that the local testers didn't do, it wasn't in his remit. When I went through all my symptoms again and asked why he thought I had these , Dr put my symptoms down to chronic fatigue syndrome if anything and did I want to join a group of like sufferers, if I wanted to look into blood tests of other I would have to do so privately. So does anyone know where I can get MMA tests privately ?
