Classification and management of refractory coeliac ...

Refractory coeliac disease (RCD) is defined by persistent or recurrent malabsorptive symptoms and villous atrophy despite strict adherence to a gluten-free diet (GFD) for at least 6–12 months in the absence of other causes of non-responsive treated coeliac disease and overt malignancy. Symptoms are often severe and require additional therapeutic intervention besides a GFD.

The refractory materials domain is highly heterogeneous. Therefore, a single LIBS spectrum cannot adequately represent it. To do a successful laser-based classification process it is necessary to have a "sampling plan", that is, clearly decide how many points must be laser-interrogated to obtain statistically significant LIBS information.
