Description

Food Sensitivity Test - IGA or IGGFood sensitivities are delayed reactions to certain foods that can appear hours or even days after eating them. These sensitivities can develop at any point in life and are often made worse by factors like stress, eating the same foods too often, a lack of variety in the diet, or underlying health issues. This test helps identify which foods may be causing these hidden reactions, so you can make better choices to support your overall health. IgG =

Food sensitivities are delayed reactions to certain foods that can appear hours or even days after eating them.

IgG = systemic, long‑term immune memory
IgA = mucosal, front‑line barrier defense

IgA tells you what’s happening at the barrier (gut, sinuses, lungs).
IgG tells you what’s happening in the system (blood, tissues).

Functional medicine treatment plans shift depending on whether the immune activation is mucosal‑driven (IgA), systemic‑driven (IgG), or mixed.

IgA - Think mucosal barrier + gut immune function.

Low IgA may indicate:

  • Mucosal immune weakness
  • Chronic gut inflammation
  • Celiac disease screening issues (false negatives)
  • Higher susceptibility to respiratory/GI infections

High IgA may reflect:

  • Chronic mucosal antigen exposure
  • Gut dysbiosis
  • Food sensitivities (mucosal-driven)
  • Autoimmune mucosal activation

IgG - Think systemic immune memory + chronic immune activation.

High IgG may reflect:

  • Past infection or chronic infection
  • Autoimmune activity
  • Persistent antigen exposure
  • Vaccination response

Low IgG may reflect:

  • Primary immunodeficiency
  • Recurrent bacterial infections
  • Poor long‑term immune memory

How They Work Together

  • IgA protects the borders (gut, lungs, sinuses).
  • IgG protects the interior (blood, tissues).

If IgA is low, more antigens cross the mucosa → IgG rises as the systemic immune system compensates.
This is why you often see low IgA + high IgG in chronic gut permeability or immune dysregulation.

How This Integrates Into a Functional Medicine Plan

Here’s the exact clinical workflow most practitioners use:

  1. Identify pattern (IgA high/low, IgG high/low, mixed)
  2. Determine source (gut, food, infection, environment)
  3. Prioritize treatment (mucosal → systemic → regulatory)
  4. Implement targeted interventions
  5. Re-test in 8–12 weeks to confirm immune normalization

This aligns perfectly with your BodyScience model of root-cause, data-driven, personalized care.

Great room separator
Color: Black
The panels are much longer than we expected! We only needed 3 of the 4 proivided. It's slightly flimsy, but holds together nicely. The screwdriver that came with did not fit the screws, but luckily we had a Phillips head. It's very lightweight. It is definitely a good value for the money.

Room divider
Color: Black, Color: Black
It was much simpler than anticipated. I don't think it's very sturdy and it lacks weight, but it's attractive.
