Abstract: A 37-year-old woman with suspected occupational allergies was referred to the National Institute for Occupational Health with results from an array of tests performed using the IgE ImmunoCAP and ISAC tests. Component-resolved diagnosis testing showed a combination of species-specific and cross-reacting sensitisation. Analyses of these results showed that she was sensitised to common environmental allergens; occupational allergies could not be diagnosed.

Keywords: ISAC, ImmunoCAP, polysensitisation, component-resolved diagnosis
