Alcat vs. IgG Testing: Understanding Food Sensitivities and Their Impact

The Complexity of Food Sensitivities

At Revital Health, we recognise the challenges faced by both patients and providers in navigating the array of food sensitivity tests. A common query is the distinction between the Alcat Test and IgG testing, particularly in their approach to identifying food and chemical sensitivities.

The Importance of Personalised Nutrition

As highlighted by Roger Williams in “Biochemical Individuality”, each individual’s response to food is uniquely influenced by their biological diversity. This concept is central to our approach at Revital Health, emphasising the need for personalised nutrition plans.

Identifying and Understanding Food Sensitivities

Food sensitivities encompass a range of reactions:

  • Allergies: IgE mediated responses, causing immediate and potentially severe reactions.
  • Intolerances: Issues in metabolising, digesting, or absorbing food components, often leading to gastrointestinal discomfort, bloating, or fatigue.
  • Sensitivities: Non-IgE mediated immune responses that can cause chronic symptoms like headaches, skin issues, joint pain, and mood disturbances.

Recognising these sensitivities is vital for long-term health and wellbeing.

Food Sensitivity Testing: Alcat vs. IgG
The Alcat Test (Leukocyte Activation)
  • Directly assesses the innate immune system’s response to foods and chemicals.
  • Employs impedance flow cytometry.
  • Validated as a reliable test, supported by research including studies from the Yale School of Medicine.
IgG/IgG4 Testing (Immunoglobulin G/antibody)
  • Measures exposure to foods, potentially reflecting tolerance.
  • Utilises ELISA method.
  • IgG4 antibodies might indicate tolerance maintenance.
Why Prioritise Food Sensitivity Testing?
  • Understanding Intolerances: Unravelling the cause of chronic symptoms and improving quality of life.
  • Individualised Dietary Planning: Tailoring diet plans to avoid trigger foods, thus reducing inflammation and associated health issues.
  • Holistic Health Approach: Addressing food sensitivities is a key component of a comprehensive wellness strategy.
Why Choose the Alcat Test?
  • Specific Immune Response: Unlike IgG tests, the Alcat Test measures direct responses, aiding in accurate identification of sensitivities.
  • Broad Testing Range: Evaluates over 450 substances for sensitivities.
  • Backed by Science: Substantial research evidence supports its reliability and specificity.
