Use: | Useful in the diagnosis of systemic bacterial infection and sepsis and optimization of antibiotic therapy. Procalcitonin (PCT) is a calcitonin precursor produced during periods of heightened inflammation. PCT production is particularly pronounced in the presence of bacterial infection. High PCT levels might indicate severe infection, and low and/or decreasing levels might assist in deciding the most appropriate time to discontinue antimicrobial therapy. |
