PCT (Procalcitonin) Test

Procalcitonin (PCT) is a protein produced by the body, primarily in response to bacterial infections and sepsis. It is released into the bloodstream and can be measured to help diagnose and monitor bacterial infections.

Why is the PCT Test Important?

1. Bacterial Infections: PCT levels rise significantly in response to bacterial infections but not viral infections, making it useful in distinguishing between bacterial and viral causes of infections.
2. Sepsis: Elevated PCT levels are associated with severe bacterial infections and sepsis, helping guide treatment decisions and monitoring response to therapy.
3. Prognosis: Helps assess the severity of infection and predict outcomes in critically ill patients.
4. Antibiotic Stewardship: Used to guide antibiotic therapy by helping to differentiate bacterial infections from other causes, thus reducing unnecessary antibiotic use.

When Should You Get a PCT Test?

• Suspected Bacterial Infection: If you have symptoms such as fever, chills, rapid heart rate, or signs of systemic infection.
• Sepsis: Used to monitor patients with suspected or confirmed sepsis.
• Critical Illness: Used in intensive care settings to assess infection severity and guide treatment.
