Procalcitonin is a precursor of the hormone calcitonin, normally produced in small amounts.

During systemic bacterial infections and sepsis, procalcitonin levels rise significantly.

Clinical uses include:

Detecting severe bacterial infections.

Differentiating bacterial vs viral infections.

Monitoring sepsis severity and progression.

Guiding antibiotic therapy (initiation, duration, discontinuation).

The test is performed using a blood sample.Procalcitonin is a precursor of the hormone calcitonin, normally produced in small amounts.
