PCT is a highly specific analyse which shows significJ1t diagnostic validities when non-viral infections are compared with rejection episodes. PCT discriminates inflammatory events such as rejec:tion or viral infections and non-viral infections including bacterial, fungal and protozoal infections. The half-life of PCT is 24 h indicating a cle< rly competent antibiotic treatment. PCT provides vital information early to clinicians and allows them to improve the management of bacteri.1l/fungal infection in immunocompromized transplant patients. PCT thus facilitates and improves the outcome of survival rate and the quality of life in the postoperative period of patients with heart, lung or liver grafts.
