Persistent stomach concerns deserve a closer look. Jivora Yersinia IgG-/IgA-antibodies™ is a professional laboratory screening designed to detect the immune system's response to Yersinia enterocolitica—a bacterium that can leave lasting immunological markers.

What is Yersinia?

Yersinia is a bacterium typically contracted through contaminated food or water. While the initial event may pass, the immune system often creates specific "defense proteins" (antibodies) that provide a record of the body's exposure.

Why Choose This Screening?

Our Dual-Antibody Test provides a multi-layered look at your immune reactivity:

  • IgA Antibodies: Markers often associated with mucosal immune activity in the gut.

  • IgG Antibodies: Long-term markers that identify a history of systemic exposure or "immune memory."

  • ELISA Methodology: We utilize standardized laboratory technology to ensure precise detection of these specific immune markers.

Who It’s For:

  • Wellness Investigators: Individuals seeking to establish an immunological baseline following periods of gastrointestinal distress.

  • Proactive Health Seekers: Those working with practitioners to identify potential environmental triggers for systemic inflammation.

  • Functional Medicine Patients: Individuals mapping their immunological history to support long-term wellness goals.



About Your Jivora Yersinia IgG-/IgA-antibodies™

Convenient Access to Wellness Insights

You can order your testing kit directly through Jivora Health, an authorized ArminLabs partner. Our streamlined online process respects your privacy and security, allowing you to take a proactive role in monitoring your immune health without the need for a prior office visit.

Simple, Needle-Free Collection at Home

Each kit features the FDA-cleared Tasso+ device, designed for easy and virtually painless blood collection from the upper arm. This innovative technology allows you to collect a high-quality sample without traditional needles. If you prefer, a standard clinical blood draw option is also available. Both methods are validated for sample stability and laboratory accuracy.

Informational Results for Better Conversations

Your report provides a detailed look at how your immune system reacts to specific tick-borne antigens. These findings are educational in nature and intended to help you have more informed discussions with your healthcare provider. Please note that these results are not a medical diagnosis and should not be used as a standalone basis for a treatment plan.

Medications and Testing

While most common medications do not impact the results, certain intensive therapies - such as strong immunosuppressants, chemotherapy, or interferon-gamma therapy - may affect your immune system’s natural reactivity. We recommend consulting your clinician before sample collection if you are currently undergoing these treatments.

Fast, Secure, and Supported

Once your sample is received by the laboratory, your secure digital report is typically available within 7 to 10 business days. To help you navigate your findings, Jivora Health provides access to a complimentary educational review to explain the data markers in your report.

Comprehensive Immune Screening

Traditional screenings often focus on a single strain of Borrelia. The ArminLabs approach provides a broader perspective by screening for reactivity to Borrelia burgdorferi, Borrelia afzelii, and Borrelia garinii. By including persistent-form (round-body) antigens, this test offers a more comprehensive view of your immune profile, reducing the limitations found in narrower testing methods.

Understanding Your Immune Markers

  • IgM Reactivity: Typically associated with a more recent or active immune response.

  • IgG Reactivity: Generally indicates an immune memory or long-term reactivity. ArminLabs calibrates these markers to provide you and your healthcare professional with a clear map of your immune system’s history and current status.

The Science of Antigen Diversity

Borrelia bacteria are known for their ability to shift forms, including "round-body" or pleomorphic states. Because these different forms can trigger different immune responses, our testing includes specific antigens for both active and persistent forms. This multi-antigen approach ensures a more thorough assessment of immune reactivity that standard screenings might overlook.


Regulatory Status: The Tasso+ collection device is FDA-cleared. The laboratory tests provided by ArminLabs are Laboratory Developed Tests (LDTs). These tests have not been cleared or approved by the U.S. Food and Drug Administration. The FDA has determined that such clearance or approval is not necessary for LDTs when performed by a CLIA-certified laboratory.

Educational Use: These results are for informational purposes only. They are not intended to diagnose, treat, cure, or prevent any disease. Always seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition.

Technical Information
key fact
Detection of specific IgG and IgA antibodies against Yersinia enterocolitica.
material
The Yersinia IgG/IgA antibody test is performed using an ELISA test. 1 tube of serum/Z-gel is required.
further information on the test
Yersinia enterocolitica-specific antibodies can be detected in the blood at the earliest 20 days after infection. In the early stage of Yersinia infection, IgA antibodies are found; in the chronic stage, specific IgG antibodies are also present.

IgA antibodies are produced by mucous membranes, including those of the nasopharynx.

If clinical suspicion of a Yersinia infection persists despite a negative antibody result, screening via Yersinia EliSpot and determination of CD3+/CD57+/CD56+/CD45+ cells is recommended.
