Joshua is currently the Chief of Chemistry at NortonHealthcare. He earned his PhD in chemistry from Carnegie Mellon University. He conducted postdoctoral research at Massachusetts Institute of Technology before completing a two-year clinical chemistry fellowship at University of Washington and 4 years as Assistant Professor at Weill Medical College. Joshua has special expertise developing and overseeing mass spectrometry assays in the clinical laboratory.

Dr. Joyce Liao has more than ten years of clinical and management experience in laboratory medicine. She was a medical laboratory scientist in the newborn screening lab and obtained her Ph.D. degree in Clinical Medicine. She completed postdoctoral fellowship training in Clinical Chemistry at the University of Washington and Seattle Children’s Hospital. She is a board-certified Clinical Chemist and now served as an Associate Director at Harborview Medical Center, focusing on toxicology and mass spectrometry testing. She continues to focus on the translation of the analytical power of mass spectrometry to real clinical applications. Her interests include toxicology, mass spectrometry, and laboratory utilization.

Dr. Stieglitz is currently an Assistant Professor at The Ohio State University Wexner Medical center and Co-Director of Clinical Chemistry and Toxicology. She received her PhD from Emory University and completed a postdoctoral fellowship in Clinical Chemistry at the University of North Carolina before joining Ohio State. She is board certified in Clinical Chemistry by the American Board of Clinical Chemistry. Her interests are in mass spectrometry-based clinical toxicology testing in adults and newborns.

Once live with mass spectrometry-based testing, clinical laboratories face the challenge of ensuring adequate data review and accurate resulting. Inevitably, labs will encounter patient results that raise the question - should I report this? This interactive discussion will attempt to address issues related to questionable patient results including those with (i) unknown interferences that might impact the accuracy of the results, (ii) low internal standard recovery, and (iii) potential carryover. The discussion will be led by three individuals currently overseeing clinical toxicology mass spectrometry testing. Examples of challenges they have faced and (occasionally) approaches they have found useful will be presented as a starting point for discussion.
