FROM THE EDITOR By Linda Wilson, Senior Edi tor


Publishing information to help guide patient care


M


edical Laboratory Observer (MLO) has been com- mitted to producing clinical reference tables for laboratories since 1972.


We continue that tradition with the 2021-22 edition of CLR.


Critical limits and reference intervals help labo- ratorians interpret test results. Critical limits estab- lish values that indicate when a patient’s medical condition may be precarious, requiring the immedi- ate attention of the provider who ordered the test. Reference intervals provide clues about test results that may require clinical follow-up to determine if a patient has a disease. It is hard to think of many


decision aids that are more important to patients’ health and well-being. As is the case every year, the editors at MLO would not have been able to produce this year’s CLR issue without help from a roster of external experts. For CLR’s core reference tables, all of which have been updated this


year, we thank the following experts: • Gerald J. Kost, MD, PhD, MS, FACB, of the University of Califor- nia-Davis Health System, for the Table of Critical Limits.


• Allison B. Chambliss, PhD, DABCC, FAACC, Director of Clini- cal Chemistry and Point of Care Testing, LAC and USC Medical Center and Assistant Professor of Clinical Pathology, Keck School of Medicine at USC (University of Southern California) for the Cutoff and Toxicity Levels for Drugs-of-Abuse and Toxicology Testing chart.


• S.T. Campbell, PhD, DABCC, FAACC, Department of Pathology, Mon- tefi ore Medical Center, Bronx, NY, for the Table of Reference Intervals.


• Steven W. Cotton, PhD, DABCC, FAACC, Assistant Professor in Pathology and Laboratory Medicine at the University of North Carolina, Chapel Hill, for the chart on Critical Values for Thera- peutic Drug Levels.


In addition, the author of last year’s special feature on pediatric


reference intervals updated the accompanying charts, which we have published again in the 2021-22 edition. For this work, we thank Maj. Matthew Raines, MD, DABP, Director and Pathologist in the U.S. Air Force. The tables were developed initially to help providers at Joint Base Elmendorf-Richardson Hospital care for their youngest patients. This year’s special feature is on a topic that has consumed us all since early 2020: COVID-19. In the article, the authors from Baylor Scott & White Medical Center – Temple, TX, discuss the impact of variable sensitivity and specifi city in tests to detect SARS-CoV-2 on costs to treat patients with COVID-19. One of the article’s authors, Amin A. Moham- mad, PhD, DABCC, said they produced the research study originally as a teaching tool for residents and students in the MLS program at Texas A&M Health Science Center. We hope our readers will fi nd the article as enlightening as we did. As always, the editors at MLO are open to conversations with


readers about information or suggestions to improve the charts and other content we publish in CLR. Please feel free to reach out to me at lwilson@mlo-online.com.
