Decoding Procalcitonin: Your Guide to This Game-Changing Infection Test
Published: Oct 08, 2023
Procalcitonin testing is changing how doctors diagnose and treat infections. This simple blood test can help distinguish between bacterial and viral infections, potentially reducing unnecessary antibiotic use.

What Exactly is Procalcitonin?
Procalcitonin is a protein produced by the body in response to bacterial toxins. In healthy people, procalcitonin levels are nearly undetectable. However, these levels can skyrocket within hours of a bacterial infection taking hold. Think of procalcitonin as your body's bacterial alarm system - when bacteria invade, procalcitonin sounds the alert.
How is the Test Performed?
The procalcitonin test is a simple blood test. A small sample of blood is drawn and sent to the laboratory for analysis. Results are typically available within a few hours. The test can be repeated every 1-2 days to monitor levels over time. This allows doctors to track how well an infection is responding to treatment.
Interpreting Procalcitonin Results
Procalcitonin levels are measured in nanograms per milliliter (ng/mL). Generally, levels below 0.1 ng/mL suggest no bacterial infection, while levels above 0.5 ng/mL indicate possible severe bacterial infection. However, interpretation isn't always straightforward. Doctors consider procalcitonin results alongside other clinical information to make treatment decisions.
Frequently Asked Questions
No, procalcitonin typically remains low in viral infections.
Levels begin to rise within 2-4 hours of infection onset.
No, it's used alongside other tests and clinical assessment.
Antibiotics don't directly affect levels, but successful treatment lowers them.
Key Takeaways
Procalcitonin testing offers exciting potential to improve infection diagnosis and treatment, but it's just one piece of the diagnostic puzzle.
