Procalcitonin: PCT as a Biomarker for Antimicrobial Stewardship

Explore the various uses and benefits of PCT within the medical field

Procalcitonin (PCT) is a crucial biomarker in clinical diagnostics. Its wide usage in diagnosing infections and sepsis saves lives every day. Discover its various usage, benefits, and even its limitations on this course, that connects procalcitonin to antimicrobial stewardship.

Discover the benefits of procalcitonin in the ICU

Even in some of the most challenging areas of the medical field, PCT is used every day. Discover the benefits of procalcitonin in and out of ICU.

Learn about the connection between procalcitonin and COVID-19

COVID-19 has changed the world. This course will explore the benefits of using procalcitonin with COVID patients, to bring you a modern and up-to-date education.

What are the limitations and controversies of procalcitonin?

This course also addresses the controversies and limitations associated with procalcitonin. Discover the other side of this biomarker, not just its benefits. After this course, you’ll be familiar with how it should be used in your practice.

Learn why procalcitonin is crucial in antimicrobial stewardship

This course will let you learn about the connection between procalcitonin and antimicrobial stewardship. Find out how PCT can benefit AMS practices and ensure antimicrobials are used appropriately to avoid antimicrobial resistance.
