Description
The P136-DIY Advanced Dietary Antigen Test from Precision Point Diagnostics is a comprehensive food sensitivity and immune reactivity assessment that evaluates reactions to 136 dietary antigens, including foods, food additives, dyes, and other commonly encountered dietary compounds. The test utilizes a convenient finger-stick blood spot collection that can be completed at home.
Unlike traditional food allergy testing that focuses primarily on IgE-mediated reactions, the P136 panel evaluates multiple immune pathways, providing a broader assessment of how the immune system responds to dietary exposures. The test measures IgE, IgA1, IgA2, IgG1-3, IgG4, and complement markers C3d/C4d across 136 antigens.
Who Should Consider This Test?
This test may be helpful for individuals experiencing:
- Bloating, gas, or digestive discomfort
- Irritable bowel symptoms
- Chronic fatigue
- Brain fog
- Headaches or migraines
- Skin issues such as eczema, rashes, or acne
- Joint pain or inflammation
- Chronic sinus congestion
- Unexplained symptoms that may be associated with dietary triggers
- Individuals seeking a personalized elimination diet strategy
What Makes This Test Different?
The P136 panel evaluates multiple immune mechanisms that may be involved in food reactions, including:
- Immediate allergic responses (IgE)
- Delayed immune responses (IgG subclasses)
- Mucosal immune responses (IgA1 and IgA2)
- Immune tolerance markers (IgG4)
- Complement activation pathways (C3d/C4d)
By assessing multiple immune pathways simultaneously, the test provides a more comprehensive view of dietary immune reactivity than tests that measure only a single antibody type.
Understanding Your Results
Results identify foods and dietary compounds that demonstrate varying levels of immune reactivity. Findings may be used to help guide:
- Personalized elimination diets
- Food reintroduction protocols
- Nutritional planning
- Investigation of potential dietary contributors to chronic symptoms
Results should always be interpreted in the context of symptoms, medical history, and clinical evaluation.
