This emphasizes the need to create a workforce equipped with technical knowledge and cutting age technology to combat allergy and immunological disorders and/or their clinical management.  


A number of biogenic or a-biogenic particles are identified as a potential source of allergens. Mold/fungi, pollen grains, dust mites, other plant and animal borne materials are identified as some common allergens. It is essential to have the proper knowledge of allergens, their prevalence and mode of action for therapeutic or clinical management of allergy and immunological disorders.

Man made/synthetic fibers, Nuisance dust, settled spores of biological nature, chemicals/dye, hair/dander, skin cells, mold etc. are common carpet allergens, particularly from older carpets.

Dust mites, cockroach, mouse, rat, bed bug etc. are identified as common allergen sources of indoor environments.
