As drug trends and diagnostic technologies evolve, toxicology must adapt to meet the demands of healthcare, workplace safety, and public health—focusing on opioid detection, CBD use, patient-centered testing, and new methods like saliva analysis, each bringing distinct challenges and opportunities. The following podcast episodes feature chemistry-related interviews that discuss these topics.

In this episode of “Answers From the Lab,” host Bobbi Pritt, M.D., chair of the Division of Clinical Microbiology at Mayo Clinic, is joined by Elitza Theel, Ph.D., director of the Infectious Diseases Serology Laboratory at Mayo Clinic, for a timely discussion on tick-borne diseases.

An effective laboratory outreach program can unlock a wide array of benefits for a health system and its laboratory. Every day, hospital laboratories struggle for dollars to meet the challenges of decreasing reimbursement and rising costs. How are they expected to survive (or possibly even thrive)? That is where laboratory outreach can make a difference. In outreach, a laboratory’s services become externally focused rather than only concentrating on the patients in hospital beds. It is the opposite of traditional lab medicine — it is entrepreneurial, intentional, and effective.

Since overcoming a life-threatening diagnosis five years ago, Jim Smith has embraced life. But each time he travels to Mayo Clinic for follow-up laboratory testing, a well of emotions rises up to remind him of life’s fragility. Thankfully, through streamlined, accurate testing and top-notch clinical care, those feelings are generally short-lived.

In this month's "Hot Topic," Kevin Halling, M.D., Ph.D., discusses new next generation sequencing testing for various tumor types and the rationale for the enhancements that were made; reviews gene additions that are now available in each of the panels; and briefly speaks about the work that was done to validate cytology specimens for use in the subpanels.
