What is the Systemic Autoimmune Reactivity Screen Array 5 by Cyrex Labs?

Autoimmune antibodies for the Systemic Autoimmune Reactivity Screen Cyrex Array 5

Many studies show that the autoimmune antibody can be elevated in the blood years before symptoms occur. Cyrex Labs have nowdeveloped their Cyrex Labs Array #5, a comprehensive autoimmune screen that helps in the early detection of autoimmunity. If detected early, natural and/or medical interventions can begin to minimize long-term illness and promote a better quality of life.

Who should consider ordering the Cyrex Labs Array #5?

This test is for those who may be at higher risk of autoimmunity. Consider ordering the Cyrex Systemic Autoimmune Reactivity Screen Array 5 if you:

  • Have a family history of autoimmune conditions like RA, Lupus, Hashimoto’s, Celiac Disease, MS, or others.
  • Are experiencing unexplained, chronic symptoms like joint pain, fatigue, brain fog, rashes, or digestive issues.
  • Currently diagnosed with autoimmune conditions. More than 40% of those with auto-antibodies in one tissue have them in other tissues. The Cyrex Array 5 lab tests the gamut of autoimmune antibodies to minimize “missing” other potential autoimmune conditions.

Are there any special preparations for the blood test?

Fasting is not required, however, it is recommended to be clear of immunosuppressants and/or corticosteroids for at least 60 days before taking this test. Please consult with your prescribing healthcare provider for guidance.

True Health’s customer service is top notch! I made a mistake when I ordered my Dutch test. I called customer service after hours, but I was able to leave a message. Rachel called me back the next morning, and we were able to get my order fixed! She was kind, helpful, and made the process smooth!

I cannot say enough great things about True Health Labs and my experience with the Marcons test. Dr. Peter Stephenson was an absolute wealth of information—extremely intelligent and insightful. He connected all the dots and made me feel like I finally have been heard and seen. After years of dealing with anxiety, OCD, weight gain, inflammation, and depression, it was incredibly comforting to talk to someone who truly understood my situation. Dr. Stephenson spoke straight to my soul and made me feel validated. Thank you, True Health Labs, for providing such an invaluable service and support. Marianne

Owner's reply
Thank you for taking that time to write that review. We’re so lucky to have Peter on the team. His insights, as you pointed out, is incredibly valuable. I’m so glad he was able to help guide you Marianne.

Ordering tests through True Health Labs was easy and painless. Peter is incredibly knowledgeable and kind. He spent more time explaining and speaking with me than any of my doctors have in the last 3.5 years. Thank you Peter, you are a blessing. And thank you THL for making it possible for the public to avoid the BS control from the medical and insurance industries.

Owner's reply
Wow! Thank you so much for that incredible review. Peter and our clinical team have a great focus on giving insights that would normally never be given. Thank you Jayme for taking the time for the review.
