What it measures
- Total IgE — A general measure of allergic antibody levels in the blood.
- Horsefly-specific IgE — Antibodies that bind specifically to horsefly saliva proteins.
- Other insect-specific IgE — Checks for cross-reactivity with similar insects like mosquitoes or deer flies.
- Serum tryptase (sometimes) — A marker that can help evaluate severe allergic reactions.
Preparation
No fasting or special preparation is needed. Tell your clinician about any medications you take, especially antihistamines, as they may affect test results.
Results and what they mean
Results are reported as a level of specific IgE, often graded from negative to strongly positive. A clinician interprets these numbers alongside your symptoms and history; a positive result alone does not confirm an allergy. This information is for general education only and is not medical advice.
