Blood-Brain Barrier Protein IgA

Measures total and specific salivary IgA against 25 different antigens that are major components of the GI tract or are introduced into it. Detects the overall integrity of the mucosal immune system, also known as our body’s first line of defense. It also detects early events associated with broken oral tolerance to many external and internal factors that are involved in the induction of leaky gut, food and chemical immune reactivity, and autoimmunity. It detects early signs and signals of autoimmunities before their appearance in the blood. Developed, published, and patented by Aristo Vojdani, PhD, MSc, CLS, known as the father of functional immunology in 2004 and 2007.

Measures IgG, IgA, and IgM antibodies against major proteins in the blood-brain barriers (S100B and Claudin-5) which maintain the integrity of the biological door against neuroautoimmunity and neurodegenerative disorders. Detects breaches of the blood-brain barriers due to various factors, including gut bacterial toxins, gut-originated amyloid beta protein and peptides, and many environmental factors, such as foods, toxic chemicals, and pathogens. This array also helps in investigating traumatic brain injuries, sport-related or otherwise. Developed, published, and patented by Aristo Vojdani, PhD, MSc, CLS, known as the father of functional immunology, in 2012, 2013, 2014, 2015, 2017, 2019, 2020, and 2024.

Measures IgG, IgA, and IgM antibodies against bacterial toxins, tight junction and cytoskeletal proteins (Array 2, 22), and blood-brain barrier proteins (Array 20).Detects disturbance of gut flora in the small and large intestine, and damage done to the gut and blood-brain structures that set the stage not only for leaky gut and leaky brain, but for the development of SIBO/IBS, inflammation, autoimmunity, neuroautoimmunity, and neurodegenerative disorders.
