LabInformation lists tests with clear descriptions so Gresham residents can decide what to order before contacting a lab.
Confidentiality is built in — orders are private and results are accessed securely. Because individual sites vary, double-check the lab's own guidance on preparation, timing, and cost.
What it measures
- Peanut-specific IgE — An antibody made by the immune system that can be linked to peanut allergy.
- Total IgE — A general measure of allergic antibody levels in the blood; it does not diagnose peanut allergy by itself.
- Peanut component proteins — Specific peanut proteins such as Ara h 1, 2, 3, 8, and 9 that may help show which peanut proteins trigger a reaction.
Preparation
No fasting is usually required. Tell your clinician about any medicines you take, especially antihistamines, because they may affect some allergy tests.
Results and what they mean
Results are reported as a number for peanut-specific IgE and, if done, for individual peanut proteins. Higher numbers may suggest allergy, but results must be interpreted by a clinician along with your history and symptoms. This is general information, not medical advice.
