About this test
The Procalcitonin (PCT) test measures procalcitonin levels in the blood to help detect bacterial infections and assess the severity of sepsis.

The Procalcitonin (PCT) test is a blood test used to measure the level of procalcitonin, a substance produced in response to bacterial infections. Under normal conditions, procalcitonin levels in the blood are very low, but they increase significantly during severe bacterial infections and sepsis.

The purpose of this test is to

  • To measure procalcitonin levels in the blood
  • To detect bacterial infections
  • To assess severity of sepsis
  • To differentiate bacterial and viral infections
  • To monitor response to antibiotic treatment
