Autoimmune neurology
A history of innovation and discovery
The Mayo Clinic Neuroimmunology Laboratory was the first to introduce comprehensive serological evaluations for the diagnosis of paraneoplastic neurologic autoimmune disorders, a group of disorders in which unusual neurologic signs and symptoms are the initial manifestations of cancer.
The laboratory continues to discover and clinically validate novel autoantibody profiles that inform neurological decision-making and guide the search for cancer, leading an evolution in autoimmune neurology diagnosis. Powered by expertise from our research labs, clinical labs, and Autoimmune Neurology Clinic, we have developed panels customized to address specific phenotypes. This approach delivers more clinically actionable results, providing a clear picture of the diagnosis, prognosis, and treatment options.
“Clinicians are used to looking for patterns in their clinical work, and we’re transferring that expertise into a clinical laboratory space. That’s not something that you learn overnight — it’s gained with experience over years.”

The latest

After mysterious neurological symptoms began in 2010, Brad Karon, M.D., Ph.D., was diagnosed with paraneoplastic syndrome, a rare condition that led to groundbreaking research and test development at Mayo Clinic. Years later, pulmonary fibrosis and a double lung transplant would test him once again — and redefine his resilience.
Mayo Clinic Laboratories has launched a first-in-the-U.S. autoimmune test of the Kelchlike protein 11 antibody, or KLHL11, which is used to detect autoimmune disease associated with testicular cancer.
In this month’s “Hot Topic,” Andrew McKeon, M.B., B.Ch., M.D., reviews the use of neurological phenotype-based evaluations, the move away from the paraneoplastic evaluation, and upcoming changes to test profiles.
Andrew McKeon, M.B., B.Ch., M.D., discusses updates that are being made to Mayo Clinic Laboratories' autoimmune profile that will remove some antibodies from those profiles. He describes the rationale behind the updates, reviews which antibodies are involved, and explains how the changes will streamline testing and enhance test interpretation.
Based on studies that have shown certain antibodies may not be as clinically relevant to autoimmune testing as previously thought, Mayo Clinic Laboratories is updating a number of its autoimmune profiles by removing some antibodies from them.
Christopher Klein, M.D., discusses Mayo Clinic’s updated myasthenia gravis and Lambert-Eaton syndrome testing approach. Automatic reflex to second-line testing saves time and increases sensitivity and specificity to confirm diagnosis in patients with atypical presentation.
Andrew McKeon, M,B., B.Ch., M.D., provides an overview of Mayo Clinic Laboratories' new paraneoplastic vision loss evaluation — a test that can help direct a cancer diagnosis and guide treatment. He reviews why this test was developed, when it should be ordered, and how the results can affect patient care.
In this month’s “Hot Topic,” John Mills, Ph.D., explains the central role of tissue immunofluorescence in the identification of neural antibodies and discusses the benefits of an integrated laboratory approach to the development and validation of novel antibody biomarkers.
The clinical presentations, evaluation (including diagnostic antibody testing), and treatment of autoimmune pediatric CNS disorders, including encephalitides and myelopathies.
