Neurological Autoimmune Reactivity Screen – Cyrex Array 7 & 7x(Expanded)

Neurological Autoimmune Reactivity Screen – Cyrex Array 7 & 7x(Expanded)

The Neurological Autoimmune Reactivity Screen Array 7 and Array 7 expanded are a useful tool to help assist in the early detection of neuro-autoimmunity. The test can highlight the severity of the autoimmune response, and assists in monitoring the effectiveness of current wellness plans.

There are two types of the Array 7. The first one looks at IgG and IgA responses where as the Array 7x (Expanded) also assesses IgM.

By including IgM, Array 7X ( Expanded) helps with early detection of neuro-autoimmune reactivity, the identification of multi-focal motor neuropathy, lower motor neuron syndromes, earlier development of relapses in multiple sclerosis and chronic inflammatory demyelinating polyneuropathy, and as a tool to monitor the effectiveness of related treatment protocols.

Recommended if you:

  • Have idiopathic neurological conditions such as Cerebellar Ataxia or Peripheral Neuropathy.
  • Show decline in brain function with accompanying fatigue or Fibromyalgia.
  • Have Gluten-Reactivity and/or Dairy-Sensitivity contributing to neurological dysfunction.

What is being measured – IgG and IgA of: (The array 7x also includes IgM of the below)

  • Myelin Basic Protein
  • Asialoganglioside
  • Alpha and 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:

a. Immunosuppressant and corticosteroid drugs can reduce antibody production and cause false negative results.
b. Limited assessments on the effects of aspirin, acetaminophen, and antipsychotics on Arrays 1-4 have been performed. No noticeable effects were observed.
c. 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.
d. 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.
e. A gluten-free diet can cause false negative results on gluten protein/peptide tests.
f. Certain conditions, such as ileal pouch surgery, may cause a false positive celiac serology.1



Specimen requirements

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

You can attend one of two laboratories in London to have the sample taken or you will need to arrange for a blood sample to be collected by a nurse at your G.P. service or at a private clinic or hospital. Any fee for this service is not included in with the test fee.

Where can I arrange a blood draw?

Returning your sample

You will need to send your sample back to the lab via a next day postal service – If you are in the UK, Royal mail offer a suitable next day service. If you are outside of the UK then please check with your postal service for options. The cost of the test does not cover the return postage.

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 -21 days.
