Novel panel identifies toxins linked to asthma and GI diseases
Answers from the Lab
Eosinophils are immune-system cells that, when activated, can play a role in a variety of diseases. In this test specific episode of the "Answers From the Lab" podcast, Melissa Snyder, Ph.D., explains how Mayo Clinic Laboratories' novel EDN panel goes beyond existing tests to provide relevant information for managing asthma and certain digestive diseases.
Standard testing quantifies eosinophils in blood — but can't determine if those immune cells have been activated and are releasing disease-related neurotoxins. The laboratories' EDN test does exactly that.
"This is the first time we'll have a marker of activation of eosinophils. It's a better way to evaluate patients," Dr. Snyder says. "EDN will be useful for managing treatment and assessing disease activity when there's a suspicion of an eosinophilic component to a patient's disease."

Patients with elevated LDL or "bad" cholesterol face even greater risk if their levels of small dense LDL cholesterol are also high. Vlad Vasile, M.D., Ph.D., and Leslie Donato, Ph.D., explain how Mayo Clinic Laboratories' sdLDL-c assay measures concentrations of the small dense LDL subtype, to better guide clinical care.
