But that first line specifically refers to testing to "exclude other diagnoses". They still seem to be saying that when other conditions are excluded, and the ME/CFS diagnosis is settled upon, B12 and the rest generally should not be tested.
I know doctors like to hide behind guidelines rather than explain there in action so I think tells them they should still be using there clinical judgement. I think the real problem in the UK is that too many GPs don't have any clinical judgement.
