What is Procalcitonin (PCT)?
PCT is the prohormone of calcitonin. Calcitonin is produced exclusively in the thyroid gland. In 2001, Müller, B. et al., found that PCT is ubiquitously and uniformly expressed in multiple tissues throughout the body in response to sepsis. Elevated circulating levels of PCT are important markers in response to microbial infections and a powerful tool in the early detection of sepsis.
The FDA has cleared a number of PCT assays for use in conjunction with other laboratory findings and clinical assessments to aid in the risk assessment of the critically ill patients on their first day of ICU admission for progression to severe sepsis and septic shock.
