This section deals with the clinical condition asthma, listing the relevant immunological tests, together with a short explanation of their use.

Relevant immunological tests: IgE and Allergen Specific IgE

Total IgE is usually raised in extrinsic asthma; specific IgE to relevant allergens is also detectable.

Specific IgE should invariably be sought against the house dust mite. Often this will suggest the appropriate animals (cats, dogs, horses, etc).

IgE to Aspergillus is associated with the need for closer monitoring and maybe more intensive steroid treatment. For seasonal asthma see seasonal rhinitis.
