PCT accurately predicts the presence of bacteraemia and bacterial load in patients with febrile UTI.[22] Some studies have shown that a PCT >2 ng/mL has >90% specificity for sepsis or the progression to sepsis, whereas <0.5 ng/mL PCT levels are not associated with sepsis.[23] We also found that the CRP, leukocyte count, and PCT upon admission were significantly higher in patients with urosepsis than in those with fUTI. Here, CRP is linked to bacterial urinary tract infection.
