The concentration of specific immunoglobulin E (IgE) to a particular substanceis an indicator of allergic sensitization. Specific IgE tests can test for hundreds of allergens, such as weeds, trees, pollen, mold, food, and animal dander—all with just one blood sample taken during a single appointment with your doctor.
Lancet offers most of these specific IgE test, the attached searchable catalogue of both native and recombinant allergens will assist in locating the test that you require.
Many of these tests are done routinely, but please do contact the relevant Lancet pathologists involved with allergy to discuss symptom profiles and a testing approach.
The website http://isitallergy.co.za provides an excellent resource for clinicians to develop a plan for personalised, effective treatment guided by quantitative results or counsel patients on targeted exposure reduction to specific triggers. Patients can also create their allergy profiles and print or store as an electronic document before consultation with their clinicians.
