...available which are specific to gluten sensitivity/intolerance as opposed to the well known tests which are diagnostic for CD....or are they basically the same tests?

Also is a Gastroenterologist the specialist of choice when it comes to investigation of CD or gluten sensitivity? Obviously neurologists and GP's are not cognisant to the fact that these things may be a causative factor in Peripheral Neuropathy. Are Gastroenterologists generally very open to the idea that someone may be gluten intolerant even if they do not have frank CD?

How valuable are the DQ2 and DQ8 genetic tests if any of the other mainstream blood tests come back positive? I realise that genetic tests tend to be more eliminative rather than diagnostic for CD, so do Gastrenterologists ever suggest having these done?

Thanks in advance for any input.
