A blood test that measures IgE antibodies to a mixture of five occupational allergens and can help identify possible allergic sensitization.
["A positive result suggests allergy sensitization to one or more allergens in the tested mixture but does not by itself confirm occupational asthma or allergy."]

What is this test?
This blood test measures allergen-specific IgE antibodies to allergens in Occupational Allergen Mix 5. The exact allergens included are listed on the laboratory report, and results are interpreted alongside your symptoms and exposure history.
Why might I need this test?
Your clinician may order this test if you have wheezing, cough, nasal symptoms, or other reactions that appear related to workplace exposures. It may also be used to help determine whether further allergy testing or workplace evaluation is appropriate.
How is the test performed?
A blood sample is collected by venipuncture and analyzed in the laboratory for allergen-specific IgE. This is a blood test and is different from skin-prick testing or a supervised allergen challenge.
How do I prepare for the test?
No special preparation or fasting is usually required. Tell your clinician about your symptoms, possible workplace exposures, allergies, and any medications or recent biologic treatments because these may help with interpretation.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A positive result indicates that IgE antibodies to one or more allergens in the tested mixture are present, suggesting allergic sensitization. It does not prove that those allergens are causing your symptoms, because sensitization can occur without clinical allergy and some results may reflect cross-reactivity. Your clinician will interpret the result with your exposure history, physical findings, and other allergy or pulmonary tests.
Short name
