The Red Cedar Tree Allergy Test is a blood test that checks whether your immune system reacts to proteins from red cedar trees. It is usually ordered when seasonal or year-round allergy symptoms need to be linked to a specific tree pollen or wood dust exposure.
What it measures
- Red Cedar Specific IgE — The main marker; it measures antibodies your body makes against red cedar proteins.
- Total IgE — A general allergy antibody level that can help put the specific result in context.
- Other Tree Pollen IgE — Sometimes tested together to see whether symptoms come from more than one tree.
- Cross-Reactive Allergens — Related proteins that can cause reactions to similar plants or foods.
Who it is for
A doctor or allergist typically orders this test for people with ongoing sneezing, nasal congestion, itchy eyes, or breathing symptoms that may worsen around red cedar trees or cedar wood products.
Preparation
No fasting or special preparation is needed. Tell your clinician about any medications you take, since some drugs can affect allergy test results.
Results and what they mean
Results are reported as a level or class for red cedar specific IgE, often alongside a total IgE value. A clinician interprets these numbers with your symptoms and history; a positive result alone does not confirm an allergy. This is general information, not medical advice.
