Description
  Array 2 – Intestinal Antigenic Permeability Screen
  The Array 2 Intestinal Antigenic Permeability Screen™ is an important initial
  screening test for patients with multiple chronic GI and neurologic symptoms,
  suspected food sensitivities, chemical intolerances, or a history of
  pathogen-induced autoimmune conditions.
What does this test measure?
  Cyrex Array 2 is a blood test checking for antibodies (IgG, IgA, IgM) against
  proteins that maintain gut lining integrity and a bacterial endotoxin:
- 
    Occludin and Zonulin are proteins involved in tight
 junctions between intestinal cells.
- 
    Actomyosin is part of the cell’s cytoskeleton that, if
 damaged, implies a deeper structural breach.
- 
    LPS (Lipopolysaccharide) is a component of gram-negative
 bacteria’s cell walls (endotoxin) that normally shouldn’t penetrate the gut
 lining.
  If a test finds elevated antibodies to occludin or zonulin, it indicates that
  the immune system is recognizing these normally internal proteins. This
  suggests that tight junctions in the gut may be breaking down and leaking.
  Additionally, high levels of LPS antibodies can indicate that bacterial toxins
  are entering the bloodstream due to a leaky gut. Overall, this serves as a way
  to validate the “leaky gut” hypothesis, which posits that the gut barrier is
  compromised and the immune system is responding to gut contents and junction
  proteins.
Who is this test most suitable for?
  This is used for patients with autoimmune conditions (to see if leaky gut
  might be a trigger), chronic inflammatory issues, or persistent GI problems.
  If positive, the patient is often advised to do a gut repair protocol (dietary
  changes like gluten removal, supplements like glutamine, etc.). It also
  distinguishes whether the issue is mainly tight junction opening
  (occludin/zonulin) or transcellular epithelial damage (actomyosin), which can
  fine-tune treatment focus.
Clinical Use
  Many functional medicine practitioners use Array 2 as a validation for gut
  barrier therapy.”
