Allergy 17: A Comprehensive Guide for Patients
The Allergy 17 test, also known as the Allergy Panel 17 or the Food Allergy Panel, plays a crucial role in diagnosing and managing various food allergies and sensitivities. Here’s an informative guide to help patients understand this important test.
Test Overview
The Allergy 17 test measures the levels of Immunoglobulin E (IgE) antibodies specific to 17 common food allergens. These antibodies are produced by the immune system in response to an allergic reaction. By measuring the levels of IgE specific to different allergens, the test can help identify the triggers responsible for an allergic reaction.
Conditions and Diseases Detected
The Allergy 17 test helps diagnose the following conditions:
- Food allergies
- Food sensitivities (non-IgE-mediated reactions to food)
- Hives
- Eczema
- Asthma
- Rhinitis
- Conjunctivitis
Preparation Guidelines
Before undergoing the Allergy 17 test, patients are advised to:
- Avoid taking antihistamines for 5 days prior to testing.
- Inform their healthcare provider about any medications or supplements they are currently taking.
- Fast for 8-12 hours prior to the blood collection.
Procedure
The Allergy 17 test is a simple blood test. A small sample of blood is drawn from a vein in the arm and sent to a laboratory for analysis. The test is generally safe and painless.
Duration and Waiting Time
The blood collection process takes only a few minutes. However, the time taken to receive the test results may vary depending on the laboratory. Patients can typically expect to receive their results within a few days.
Additional Tests
In some cases, additional tests such as skin prick testing or oral food challenges may be recommended for further confirmation of an allergy or sensitivity.
Conclusion
The Allergy 17 test is a valuable diagnostic tool for identifying food allergies and sensitivities. It can help patients avoid triggers, manage their symptoms, and improve their quality of life. Patients who suspect they have a food allergy or sensitivity are encouraged to discuss the test with their healthcare provider to determine if it is right for them.
