As the world leader in the diagnosis and treatment of neurologic conditions, we know the importance of laboratory testing in a patient's episode of care. Our disease-specific tests are clinically proven, cost effective, and patient care-driven. In addition to the latest testing, when you partner with us, you extend your network to include some of the world's leading neurology experts. Our neurologists are available for consultation seven days a week to provide interpretive expertise and support.

Visit us at booth #1301 at AAN 2019 to discuss how our testing can integrate with your practice.

Clinical Application of a New Antibody Discovery

A novel astrocytic autoantibody, glial fibrillary acidic protein (GFAP) has recently been described by Mayo Clinic as a biomarker of a relapsing autoimmune meningoencephalomyelitis that is responsive to immunotherapies. Seropositivity distinguishes autoimmune GFAP meningoencephalomyelitis from disorders commonly considered in the differential diagnosis. This biomarker will be available in June in all of our CNS evaluations.

CNS Demyelinating Disease (AQP4-IgG & MOG-IgG)

Testing for AQP4 and MOG antibodies allows for the most comprehensive evaluation for patients recently diagnosed with demyelinating diseases and distinguishes a spectrum of demyelinating disease from multiple sclerosis.

Mayo Clinic has developed the only fluorescence-activated cell sorting (FACS) live cell-binding assay that is currently available in the U.S. for antibody detection of AQP4 and MOG. FACS is recommended by international leaders in neuroimmunology for its increased sensitivity and specificity.

A recent study also found that live cell-based methodologies had superior PPVs to the fixed cell assays, indicating that positive results in these assays are more reliable indicators of MOG autoimmune spectrum disorders.

Comprehensive Testing for Genetic Disorders

Our full menu of genetic testing focuses on genes with clinical significance and focuses on providing answers for your patients, not confusing results. Our comprehensive test menu includes hereditary epilepsy, mitochondrial disorders, peripheral neuropathies, neuromuscular diseases, and several others.

Orexin-A /Hypocretin-1

This test has major practical implications for the diagnosis of narcolepsy with cataplexy (narcolepsy type 1). It can be utilized in the diagnosis of narcolepsy type 1, and distinguishing it from narcolepsy type 2 and idiopathic hypersomnia.

Kappa Free Light Chain

The Kappa Free Light Chain, CSF test marks a new frontier in MS testing. The test is an automated and quantitative and requires only one CSF sample, simplifying lab workflows and reducing time. Furthermore, it has comparable sensitivity and specificity to oligoclonal banding, which requires CSF and serum samples as well as specialized laboratories.

Neuro-Oncology Testing

We offer a comprehensive approach to testing that focuses on the best outcomes for the patient. Our testing method combines molecular and cytogenetic analysis (in addition to a standard morphological and
histological assessment) to provide a clear picture of the diagnosis, prognosis, and treatment options. This approach maximizes the amount of information available, allowing for a tailored treatment plan.
