Do We Need Procalcitonin for Sepsis in 2019?
Procalcitonin (PCT) is the peptide precursor of calcitonin, a hormone that is synthesized by the parafollicular C cells of the thyroid. The reference value of procalcitonin in adults and children older than 72 hours is 0.15 ng/mL or less. Severe bacterial infection, b acterial sepsis is associated with elevated serum procalcitonin levels (>2 ng/mL).
