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.
