What it measures
- Blackberry-specific IgE — The main marker; it measures antibodies your immune system makes against blackberry proteins.
- Total IgE — Sometimes included to show your overall allergy-related antibody level.
- Cross-reactive allergens — May check for similar proteins in other berries or fruits that can cause related reactions.
Preparation
No fasting or special preparation is needed. You can eat and drink normally before the blood draw.
Results and what they mean
