Comparison of CRP versus PCT (advantages and disadvantages).
| | CRP | PCT |
| Differentiating bacterial infection from SIRS | − [27] | Specific for bacteria [28, 29] | Response to infection | Slower (days) [27] | 2–6 hours [30] | Peak response after infection | 2-3 days [27] | 12–48 hours [27] | Half-life | Several days [27] | 20–35 hours [31] | Plasma kinetic | Slow [27] | Rapid [27] | Price | + | ++++ | Correlating disease severity and progression | Slightly [27] | +++ [32] | Correlating effective therapy | + | +++ [33, 34] | Prognostic factor for mortality | Weak or nonexistent [27] | Good predictor [31, 32] | Differentiating G+ from G− | − [35] | ++ [35] | Response to other factors | Virus, autoimmune diseases, local infections, surgery, trauma [27] | Surgery, trauma, burn, cardiogenic shock, liver cirrhosis [36–38] | Fungal infection | same as bacterial [35] | Slightly elevated [35] | Immunosuppression | Formation can be changed [27] | The induction is reduced [27] | Biological effect | Opsonin for phagocytosis [27] | Chemokine [27] | Sensitivity/specificity | Sensitive but nonspecific [27] | Sensitive and specific [27, 39] | General use | Outpatient care [27] | In intensive care [27] |
