Procalcitonin und seine Bedeutung für die Diagnose bakterieller Infektionen / Procalcitonin: Importance for the diagnosis of bacterial infections

Zusammenfassung Procalcitonin ist das Pro-Hormon von Calcitonin. Im Gegensatz zu Calcitonin, welches primär in der Schilddrüse gebildet wird, wird Procalcitonin bei einer bakteriellen Infektion im Körper von allen infizierten parenchymatösen Organen produziert. Insbesondere bei der Diagnosestellung milder, lokalisierter oder beginnender Infektionen muss ein empfindliches Verfahren verwendet werden mit einer funktionellen Sensitivität, die idealerweise in dem Bereich gesunder Individuen messen kann (ca...
