Basophil Activation Test : A diagnostic, predictive and monitoring assay for Allergen Immunotherapy.

For decades, the approach to clinical care has involved the assessment of a fairly small set of patients' signs and symptoms, sampled over a short period of time with limited attention given to individual variations in aetiology and pathophysiology. Subsequently, a therapy is assigned predominantly with a "one shoe fits all" approach. Precision medicine approaches are now starting to change ways to test, treat and develop new therapies for allergic and immunological disorders. (Figure 1).
