What it measures
- Mustard-specific IgE — The main marker: an antibody that can be linked to allergic reactions to mustard.
- Total IgE — A general measure of allergic antibody levels; it does not diagnose mustard allergy by itself.
- Other specific IgE (if tested) — Sometimes other foods are checked at the same time to help find the cause of symptoms.
Preparation
No fasting or special preparation is required. Tell your clinician about any medicines you take, because some can affect allergy testing.
Results and what they mean
Results are reported as a level or class for mustard-specific IgE, along with a reference range from the lab. A clinician interprets the result with your symptoms and history; a single number cannot confirm or rule out an allergy. This is general information, not medical advice.
