About pistachio allergy testing in Fallbrook
Fallbrook is a large town in Pacific, where residents have dependable access to clinical laboratory services. Across Pacific, there is coastal metros, inland towns, and rural counties with very different access to testing.

Your request stays private, and you choose where the specimen is collected. Because individual sites vary, double-check the lab's own guidance on preparation, timing, and cost.
What it measures
- Pistachio-specific IgE — The main marker. IgE is an antibody linked to allergic reactions; this measures how much of it binds to pistachio proteins.
- Total IgE — Sometimes measured to give context, but a high total IgE alone does not mean you are allergic to pistachio.
- Component allergens (optional) — Specific pistachio proteins may be tested to help estimate reaction risk, but not all labs offer this.
Preparation
No fasting or special preparation is needed. You can eat and drink normally before the blood draw.
Results and what they mean
Results are reported as a number for pistachio-specific IgE, often with a reference range. A higher number suggests sensitivity, but the result must be interpreted by a clinician along with your symptoms and history. This is general information, not medical advice; talk to your clinician about what your result means for you.

Frequently asked questions
Does a positive result mean I am definitely allergic?
No. A positive test shows your immune system makes IgE to pistachio, but only a clinician can tell if you have a true allergy based on your symptoms and exam.
Can I take this test if I am already having a reaction?
No. If you have trouble breathing, swelling, or other severe symptoms, seek emergency care right away. This test is for non-urgent evaluation.
Do I need to stop my allergy medicines before the test?
Usually not for a blood test. Antihistamines do not affect IgE blood results, but check with your clinician about any medicines you take.
How long until I get results?
Most labs return results in 1 to 3 business days. Your clinician's office will contact you to discuss them.
