Objectives

  • Identify the basics of number rounding and the use of significant figures in the context of laboratory medicine.
  • Explain the interconnectivity of systems of measure and how to convert between different units.
  • Perform dilution calculations to determine necessary volumes of sample, reagent, or diluent based on common laboratory scenarios.
  • Describe common laboratory equations such as Beer's Law, Henderson-Hasselbalch, Anion Gap, and Osmolal Gap and how their applications are essential.

Additional Information

Level of Instruction: Basic
Intended Audience: Medical laboratory scientists and technicians. This course is also appropriate for medical laboratory science students and pathology residents.
Author Information: Alec Saitman, PhD, DABCC (CC, TC) completed fellowship training in Clinical Chemistry and Toxicology in the Department of Pathology at the University of California, San Diego. Dr. Saitman is board certified by the American Board of Clinical Chemistry (ABCC) in Clinical Chemistry and Toxicological Chemistry. He is currently the Technical Director of the Core Laboratory at Providence Regional Laboratories in Portland, Oregon. His research focuses on the development of small molecule quantitation assays using mass spectrometry. He is particularly interested in establishing efficient production workflows in toxicology testing to meet the growing testing demands in his laboratory.
Reviewer Information: Roger Beckering, M.Ed., BA (Chemistry), MLT(ASCP) has been an educator of medical laboratory sciences for over 25 years. He started as an instructor at the Medical Institute of Minnesota (MIM), later known as Argosy University. At Argosy, Roger held positions as Professor, Clinical Coordinator, and Program Director. In 2014, Roger moved to the Phoenix area where he works as a Professor and Administrator for MLT and MLS programs at Brookline College.
