Procalcitonin (PCT) is a peptide precursor of the hormone calcitonin, the latter being involved with calcium homeostasis. It arises once preprocalcitonin is cleaved by endopeptidase. It was first identified by Leonard J. Deftos and Bernard A. Roos in the 1970s. It is composed of 116 amino acids and is produced by … Se mer PCT is a member of the calcitonin (CT) superfamily of peptides. It is a peptide of 116 amino acid with an approximate molecular weight of 14.5 kDa, and its structure can be divided into three sections ( Se mer Due to PCT’s variance between microbial infections and healthy individuals, it has become a marker to improve identification of bacterial infection and guide antibiotic therapy. The table … Se mer Excessive overdose on amphetamine or its analogs can induce systemic inflammation; in a case report of amphetamine overdose, sans bacterial infection, significant elevations … Se mer Sepsis Measurement of procalcitonin can be used as a marker of severe sepsis caused by bacteria and generally grades well with the degree of sepsis, although levels of procalcitonin in the blood are very low.

PCT does not elevate in response to localized infections, only major infections. Of particular importance is that this biomarker does not respond to viral or fungal infections, which is how it derives its value for antibiotic stewardship.
