Basophil activation testing in occupational respiratory allergy to low molecular weight compounds
Purpose of review There is an unmet need for better immunological tests in cases of suspected occupational asthma to many workplace chemicals; here we consider the basophil activation test (BAT), a potential alternative to the detection of specific IgE antibodies.
Recent findings BAT is fairly widely used in general allergy services; and there is increasing experience of its use in the diagnosis of occupational allergy to low molecular weight agents and chemicals including wood dusts, persulphates, antibiotics and latex.

Patterns of mouse allergen–specific IgE and IgG4 in contemporary animal research environments
Laboratory animal allergy (LAA) results from occupational ex-posure to allergens found in the hair, dander, urine, and salivaof laboratory animals. It presents as work-related rhinocon-junctivitis and occupational asthma after a latency period of2–3 years. Prevalence of rodent-sensitisation among laboratoryanimal (LA) workers ranges between 10.4% [1] and 28% [2].Though exposure is a major risk factor, some individuals developallergen-specific IgE without progressing to LAA symptoms andare considered clinically tolerant [3].
