By including IgM, Array 7X helps with early detection of neuro-autoimmune reactivity, the identification of multi-focal motor neuropathy, lower motor neuron syndromes, early development of relapses in multiple sclerosis and chronic inflammatory demyelinating polyneuropathy, and as a tool to monitor the effectiveness of related treatment protocols. The test can highlight the severity of the autoimmune response, and assists in monitoring the effectiveness of current wellness plans.

Clinical Use

  • Detection of immune reactivity in pathogenesis of neuro-inflammatory, neuro-autoimmune and neuro-degenerative disorders
  • Early detection of autoimmune reactivity of both peripheral and central nervous system
  • Assist in monitoring the effectiveness of related treatment protocols

Recommended for Patients Who

  • Have idiopathic neurological conditions such as Cerebellar ataxia or Peripheral Neuropathy
  • Show decline in brain function with accompanying fatigue or Fibromyalgia.
  • Have Gluten-Reactivity, Dairy Sensitivity and/or enhanced permeability of the Gut and/or Blood-Brain Barrier

Antigens Tested (IgG + IgA Combined, IgM tested separately for each antigen)

  • Myelin Basic Protein
  • Asialoganglioside
  • Alpha + Beta Tubulin
  • Cerebellar
  • Synapsin

Before Taking A CYREX Test

While Cyrex is unable to provide an exhaustive list of medications due to the interactive complexities and varieties of medications and patient circumstances, the following has been noted:

  • Immunosuppressant and corticosteroid drugs can reduce antibody production and cause false negative results.
  • Limited assessments on the effects of aspirin, acetaminophen, and antipsychotics on Arrays 1-4 have been performed. No noticeable effects were observed.
  • Inhalers can affect the results of Cyrex’s oral fluid testing (Array 1). Wait two weeks after completion of inhalant dosages before collecting the specimen.
  • Unknown cross-reactive epitopes from foods and microorganisms may stimulate the antibody production in the absence of a true antigen. Cyrex has already developed Array 4 in order to recognize the most common antigens in this regard.
  • A gluten-free diet can cause false negative results on gluten protein/peptide tests.
  • Certain conditions, such as ileal pouch surgery, may cause a false positive celiac serology.


Specimen requirements

Blood test that requires a blood sample. The blood sample will need to be centrifuged.

Returning your sample

You will need to send your sample back to the lab via a next day postal service –

Please note that samples should only be posted on Monday – Thursday so that they do not arrive over the weekend when the lab is closed.

Turnaround time

14 days or sooner.
