    Procalcitonin (PCT), the precursor of the hormone calcitonin, is primarily expressed in thyroid C cells and PCT serum levels in healthy individuals are very low (< 0.05 ng/mL). In response to microbial systemic infections and sepsis, PCT is ubiquitously expressed in multiple tissues via stimulation by inflammatory cytokines or bacterial endotoxins and may increase up to 1000 ng/mL.
