    An Interview With Dr. Alan Remaley, Dr. Anna Wolska, and Maureen Sampson: Advancing LDL-C Calculation With Modern Equations

    The Friedewald equation has been the standard method for estimating low-density lipoprotein cholesterol (LDL-C) for more than 50 years. However, newer equations can reduce the negative bias that may occur at high triglyceride concentrations or low LDL-C levels, improving the accuracy in cardiovascular disease risk assessment. But if newer calculations are available, why haven't they been adopted more broadly? This episode of LabMind features three scientists from the National Institutes of Health (NIH): Alan Remaley, MD, PhD, FAHA, senior investigator in the Lipoprotein Metabolism Laboratory at the National Heart, Lung, and Blood Institute; Anna Wolska, MS, PhD, FAHA, associate scientist in the Lipoprotein Metabolism Laboratory, and Maureen Sampson, BSMT(ASCP), research clinical laboratory scientist in the Chemistry Service of the Department of Laboratory Medicine at the NIH Clinical Center. They joined us to discuss the evolution of LDL-C estimates and the opportunities associated with implementing newer equations in clinical laboratories. Listen in for an insightful conversation on how advances in lipid testing can improve the assessment of atherosclerotic cardiovascular disease risk.

    An Interview With Dr. Ryan Nelson: Using Pharmacogenetics To Minimize Toxicity With Chemotherapy

    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.   Related Information: FDA: Safety Labeling Update: Capecitabine and Fluorouracil (5-FU), Risks Associated With DPD Deficiency. 2026. fda.govFDA: VISTOGARD (uridine triacetate) Prescribing Information. 2015.NCCN: Clinical Practice Guidelines in Oncology: Colon Cancer, v5.2025 (Oct 30, 2025).Nelson R, Shaaban S.

    An Interview With Dr. Patricia Slev: Laboratory Evaluation of Vaccine-Induced Immunity

    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. Related Information: To Vaccinate or Not To Vaccinate: A Laboratory Perspective by Patricia R.

    An Interview With Dr. Joe Wiencek: Reducing Waste in Clinical Laboratory Testing

    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.   Related Information: Estimated Waste Generation From 1 Million Basic Metabolic Panels: A Multisite U.S. Study [hyperlinked to: https://pubmed.ncbi.nlm.nih.gov/41048040/]Potential Savings of Two Practical Interventions on Vitamin D Ordering Practices at a Large Academic Medical Center [hyperlinked to: https://pubmed.ncbi.nlm.nih.gov/41140116/]
