About our laboratory

We are an ISO-accredited laboratory service dedicated to specific antibody and aeroallergen measurement for occupational and environmental issues.

We provide a specialist immunological service for the diagnosis of occupational lung disease, working in close collaboration with clinical colleagues from the Royal Brompton Hospital.  We are also the only UK site currently carrying out beryllium lymphocyte proliferation tests. A full list of our services include:

  • Measurement of specific IgE and IgG antibodies to allergens
  • Extraction of allergens for measurement of specific IgE or IgG
  • Bespoke specific IgE assays for novel occupational and environmental allergens
  • Precipitation assays for the measurement of specific IgG antibodies
  • T cell (lymphocyte) proliferation assays to beryllium
  • Allergen extraction from air filters
  • Rat n 1 and Mus m 1 aeroallergen measurements
  • Research and development of new diagnostic assays
  • Specialist advice on diagnostic assays and interpretation of results
  • Immunological health surveillance
