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.
