Joshua Bornhorst, Ph.D., explains how Mayo Clinic Laboratories' labile copper assay (Mayo ID: LBCS) improves upon standard blood tests for Wilson's disease. The new assay measures not just overall copper but also the fraction of copper that is bioavailable, or labile bound.

John Lieske, M.D., and Sandra Taler, M.D., explain how Mayo Clinic Laboratories' mass spectrometry assay helps evaluate patients for resistant hypertension. The test can detect antihypertensive medications in urine, providing evidence of whether patients are actually absorbing their medications or whether a new approach might be needed.

Joseph Yao, M.D., explains how Mayo Clinic Laboratories' new quantitative assay (Mayo ID: ADVQU) goes beyond qualitative testing to evaluate transplant patients for adenovirus infection. Adenovirus can cause life-threatening disease in immunocompromised transplant patients, especially children.

Paul Jannetto, Ph.D., explains how Mayo Clinic Laboratories' SPAS test identifies the form of arsenic present in patients with arsenic exposure. That information is important for determining the potential level of harm and for removing the patient from the arsenic source to ease symptoms and prevent cancer risk.

Jessica Wright, Pharm.D., BCACP, explains how Mayo Clinic Laboratories' 3A5Q test helps determine initial tacrolimus doses for individuals after non-liver organ transplants. Optimal tacrolimus levels are one of the important factors in survival of the transplanted organ.

Sanjeev Sethi, M.D., Ph.D., explains how Mayo Clinic Laboratories' new mass spectrometry test (Mayo ID: MSMN) identifies most antigens now known to cause membranous nephropathy. Precise identification of antigens is important for optimal management of this serious kidney disease.

Matthew J. Schultz, Ph.D., and Amy L. White, M.S., CGC, explain how Mayo Clinic Laboratories' unique urine assay (Mayo ID: SORD) screens for peripheral neuropathy arising from SORD gene variants. Although recently identified, SORD-related peripheral neuropathy is fairly common.

John Mills, Ph.D., and Divyanshu Dubey, M.B.B.S., explain how Mayo Clinic Laboratories' new test panel can distinguish among various potential causes of demyelinating neuropathies. Test results are important for managing these devastating autoimmune conditions.

Ann Moyer, M.D., Ph.D., explains how Mayo Clinic Laboratories' unique genetic tests identify patients at high risk of severe reactions to fluoropyrimidines — a type of chemotherapy drug. Test results can guide clinical decision-making for safer cancer treatment.

Maria Alice Willrich, Ph.D., and Melissa Snyder, Ph.D., explain how Mayo Clinic Laboratories' unique risankizumab panel measures levels of both that drug and its antibodies in patients' blood. The results can better guide the management of patients with inflammatory bowel disease.

Anastasia Zekeridou, M.D., Ph.D., explains how Mayo Clinic Laboratories' updated panels and methodology boost the accuracy and efficiency of testing for three autoimmune neurology biomarkers. Early diagnosis is key to managing debilitating conditions associated with these antibodies.

Divyanshu Dubey, M.B.B.S., explains how Mayo Clinic Laboratories' unique PDE10A and TRIM46 tests facilitate the management of central nervous system disorders triggered by cancers. Early diagnosis and treatment are important for managing disabling neurological symptoms and malignancy.
