The Procalcitonin (PCT) Test is used to assess the presence of bacterial infections. Procalcitonin is a protein that increases in response to bacterial infection but remains low in viral infections, making it a useful marker for distinguishing between bacterial and viral causes of symptoms like fever or sepsis.
Indications for Procalcitonin Test:
● Sepsis diagnosis: To evaluate and diagnose systemic infections or sepsis.
● Respiratory infections: Used in assessing bacterial pneumonia, bronchitis, or sinusitis.
● Post-surgical infections: To monitor for infections following surgery or trauma.
How Procalcitonin Test Works:
● A blood sample is drawn and analyzed for procalcitonin levels. High levels indicate the presence of bacterial infections, while low levels suggest a viral cause or absence of infection.
Normal Range:
● Normal levels: Less than 0.05 ng/mL.
● Elevated levels: Higher levels indicate a bacterial infection, and the higher the level, the more severe the infection.
Abnormal Test Significance:
● High procalcitonin levels: Suggest bacterial infections, including sepsis, pneumonia, or meningitis.
● Low levels: Suggest that the infection may be viral, or there is no significant infection.
Management Based on Results:
● For high procalcitonin levels: Antibiotic therapy or other targeted treatments may be started for bacterial infections.
● For low levels: The healthcare provider may consider other causes or viral infections and may monitor the patient’s symptoms.
Price in India:
Approx. ₹1,000 – ₹3,000 for a procalcitonin test.

No, procalcitonin levels are usually low in viral infections.
How accurate is the procalcitonin test in diagnosing sepsis?
It is a reliable marker for bacterial infections but should be used alongside clinical judgment and other tests.
Disclaimer: The procalcitonin test is a screening tool for bacterial infections and should be interpreted alongside clinical symptoms and other diagnostic results.
