Strategic use of molecular point-of-care tests can improve respiratory testing outcomes

By Annanya Shetty, PhD

This course examines the strategic use of molecular point-of-care (POC) testing for respiratory infections. It explores the advantages of molecular POC tests compared with traditional rapid antigen tests, key factors in selecting and implementing POC platforms, and the hub-and-spoke testing model. The course also highlights how combining POC and laboratory-based testing can support diagnostic stewardship, improve turnaround times, reduce unnecessary testing, and enhance clinical decision-making.

LEARNING OBJECTIVES

Upon completion of this article, the reader will be able to: 

1. Identify the key differences between traditional rapid antigen tests and molecular point-of-care (POC) tests, including their relative sensitivity and specificity.
2. Describe the components and functions of the hub-and-spoke model for respiratory testing within a healthcare system.
3. Evaluate the factors that influence the selection and implementation of molecular POC testing platforms, including turnaround time, connectivity, and portability.
4. Analyze how molecular POC testing and laboratory-based testing support diagnostic stewardship by reducing unnecessary testing and improving clinical decision-making.
