A single genetic variant can make the difference between effective cancer treatment and life-threatening toxicity. In this episode of LabMind, Ryan Nelson, PharmD, medical director of Precision Medicine at ARUP Laboratories and adjunct professor at the Spencer Fox Eccles School of Medicine at the University of Utah, shares how a growing movement led by patient advocates, researchers, healthcare organizations, and regulators has driven critical updates to guidelines for prescribing fluoropyrimidines, a major class of chemotherapy drugs. Tune in to learn why pharmacogenetic testing is becoming an important tool in cancer care, helping clinicians identify at-risk patients, reduce serious adverse events, and deliver safer, more cost-effective treatments.

Laboratory billing is a complex and often challenging aspect of healthcare, yet appropriate reimbursement is essential to sustain operations and support high-quality patient care. In this episode of LabMind, Ashley Zarling, director of Business Development and Marketing at Doc Lab, shares practical strategies for developing and maintaining effective laboratory billing solutions. This discussion also explores key trends and emerging challenges in the evolving landscape of laboratory billing and compliance. Join us for an insightful and engaging conversation on this critical, but often underappreciated, component of clinical laboratory operations.

Vaccination has been at the forefront of public discourse in recent years, yet the role of clinical laboratory testing in evaluating vaccination status has been largely overlooked. In this episode of LabMind, Dr. Patricia Slev, professor of Pathology at the Spencer Fox Eccles School of Medicine at the University of Utah, explores how immune response to vaccines can be assessed through clinical laboratory diagnostics. This conversation brings a scientific and personal health perspective to a complex topic, highlighting how evidence-based laboratory medicine can help inform our understanding of this important issue. Join us for this timely and thought-provoking discussion about vaccine-induced immunity.

Clinical laboratories play a critical role in patient care while also generating substantial waste, including single‑use plastics, paper, and e-waste. In this special Lab Week episode of LabMind, we sit down with Dr. Joseph Wiencek, associate professor of Pathology, Microbiology, and Immunology at Vanderbilt University Medical Center, to explore practical and attainable ways laboratories can reduce their environmental footprint. Dr. Wiencek shares actionable strategies for improving sustainability through laboratory stewardship, recycling initiatives, and effective advocacy without compromising quality or safety. Whether you’re a laboratorian, administrator, or trainee, this conversation offers ideas you can implement immediately. Listen in as we rethink waste in the clinical laboratory and consider how you can contribute to a more sustainable future in laboratory medicine.

The doctorate in clinical laboratory science (DCLS) is designed to address critical practice needs involving high-complexity CLIA laboratory directorships and effective laboratory representation with clinical services across the health system. This episode of LabMind features guests Dr. LaShanta Brice, scientific engagement and clinical education scientist at Diagnostica Stago, Dr. Melody Nelson, assistant clinical professor in the Department of Pathology at the University of Kansas Medical Center, and Dr. Kacy Peterson, director of laboratory optimization and clinical integration and laboratory service line administrator at Avera Health. They join us to discuss their laboratory careers, the value of the DCLS degree, and the ways the degree has helped to empower their laboratory, clinical, and scientific leadership across different practice settings.

New blood-based tests for Alzheimer's disease (AD) are advancing and reshaping how this devastating disorder is detected and treated. In this episode, Dr. Christine Cliatt Brown, assistant professor in the division of Cognitive Neurology at the University of Utah, and Dr. Heather Nelson, assistant professor in the department of Pathology at the University of Utah and medical director of Clinical Chemistry and Mass Spectrometry at ARUP Laboratories, discuss how emerging diagnostics are transforming the diagnosis and management of AD. Together, they explore how collaboration across clinical and laboratory disciplines can accelerate diagnostic innovation and support advances in patient care.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a genetic condition that can lead to life-threatening hemolysis in both children and adults. Early and accurate diagnosis is critical, but identifying G6PD deficiency in newborns and young children isn’t always straightforward—most reference intervals are based on adult values, which don’t necessarily apply to pediatric patients. In this interview, Dr. Kelly Doyle, an ARUP medical director of Special Chemistry, Endocrinology, and Mass Spectrometry, shares insights from novel methods to establish pediatric-specific reference intervals. Using an innovative indirect approach and a large dataset of patient results, Dr. Doyle explains how these new standards can improve diagnosis and care for children worldwide.
