Antimicrobial susceptibility testing determines whether these bacteria are susceptible or resistant to a particular antibiotic. Bacteria are added onto plates of solid agar, where each plate has a different and increasing concentration of antibiotic than the previous plate. The minimum inhibitory concentration (MIC) is the lowest concentration of an antimicrobial that inhibits growth of the bacteria.

With input from Mayo Clinic oncologists, our laboratories have developed a menu of next-generation sequencing (NGS) oncology panels. These panels aid in the diagnosis and management of patients with cancer and are optimized for clinically relevant genes and actionable targets consistent with current oncology guidelines.

Targeted cancer therapies are defined as antibody or small molecule drugs that block the growth and spread of cancer by interfering with specific cell molecules involved in tumor growth and progression. Multiple targeted therapies have been approved by the US Food and Drug Administration (FDA) for treatment of specific cancers. Molecular genetic profiling is often needed to identify targets amenable to targeted therapies and to minimize treatment costs and therapy-associated risks.

PD-L1 immunohistochemistry (IHC) is indicated in patients with specific tumor types in order to predict their responses to treatment with PD-L1 inhibitors. The specific PD-L1 clone, scoring method, and eligibility requirements are dependent on the tumor type, stage of malignancy, previous treatment outcomes, and specific PD-L1 inhibitor being considered.

Mayo Clinic Laboratories is the only laboratory in the world to offer testing for a novel form of autoimmune meningoencephalomyelitis. Known as autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy, the condition was identified by Mayo Clinic in 2016. The GFAP antibody test is offered as part of Mayo Clinic Laboratories’ encephalitis and myelopathy evaluations.

Patients with autoimmune myelopathy present with subacute onset and rapid progression of spinal cord symptoms (weakness, gait difficulties, loss of sensation, neuropathic pain, and bowel and bladder dysfunction). Autoimmune myelopathy evaluation of serum and spinal fluid can assist in the diagnosis and aid distinction from other causes of myelopathy (multiple sclerosis, sarcoidosis, and vascular disease). Early diagnosis may assist in diagnosis of occult cancer, prompt initiation of immune therapies, or both.
