Webb22 jan. 2024 · Procalcitonin (PCT) is a biomarker used to assess systemic inflammation, infection, and sepsis and to optimize antimicrobial therapies. Its role in the in the differential diagnosis between candidemia and bacteremia is unclear. WebbProcalcitonin (PCT) is a peptide precursor of the hormone calcitonin, synthesized by the parafollicular cells of the thyroid gland, and involved in calcium homeostasis. The major function of calcitonin is to decrease calcium absorption by osteoclastic cells, which increases circulating calcium levels. The half-life of PCT is 25–30 hours.

WebbProcalcitonin is an excellent marker for severe, invasive bacterial infection in children. However, the use of procalcitonin in the diagnosis of neonatal bacterial infection is complicated, but if correctly used procalcitonin results in a higher specificity than C-reactive protein. WebbProcalcitonin (PCT) is a 116 amino acid prohormone with a molecular weight of approximately 12.7 kD. PCT is expressed by neuroendocrine cells (C cells of the thyroid, pulmonary and pancreatic tissues) and successively enzymatically cleaved into (immature) calcitonin, katacalcin, and an N‑terminal region. ribbon\u0027s 4a
