Does anyone know if the above enzyme metabolisation testing is avaliable in the UK? If so can it be done on the NHS? I've tried to ask my GP about it to see if it's the cause of my problems with codeine, tramadol etc.

Though he says it's a good possibility; he has left me with the fact finding if I want to get the test done: So can anybody point me in the right direction?

Many Thanks,

mr_colt.
