Array 20 – Leaky Brain

What this laboratory test evaluates

This test 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. It 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.

How Sunridge uses laboratory information

Sunridge considers the medical question, symptoms, history, medications, prior results, and whether the finding could change care before recommending testing. A laboratory result is not interpreted in isolation and does not establish a diagnosis by itself.

Before requesting this test
