The Cyrex Alzheimer’s LINX™ test (Alzheimer’s-Associated Immune Reactivity) is a specialized immunological screening designed to detect immune reactivity linked to Alzheimer’s disease and other neurodegenerative conditions, potentially identifying risk factors years before symptoms appear
 
 
What It Tests
The test measures IgG immune reactivity to a wide range of antigens, including:
Brain proteins beyond amyloid-beta and tau (e.g., Rabaptin-5, Presenilin, Alpha-Synuclein).
Growth factors like BDNF and NGF, important for neuronal regeneration.
Enteric nerve and neurological peptides linking gut and brain health.
Pathogens known to cross-react with amyloid-beta (e.g., Enterococcus faecalis, Salmonella, Campylobacter jejuni).
Chemicals such as aluminum, mercury, phthalates.
Foods cross-reactive to amyloid-beta (e.g., egg yolk, lentils, tuna, hazelnuts, cashews, scallops, squid, wheat proteins).
Blood-brain barrier integrity and neurofilament proteins
