Sepsis is the most common cause of death in intensive care units (ICU) with a mortality rate up to 50% depending on severity. The earlier sepsis is identified and treated, the better the prognosis (1,2). PCT levels in sepsis are often greater than 1 μg/L and reach values of 10 μg/L or even higher with severe sepsis and septic shock. As the septic infection resolves, the PCT levels also return to ranges < 0.5 μg/L, with a half-life of 24 hours. The IB10 sphingotest® PCT is only intended for the diagnosis of sepsis, the assessment of the degree of severity, and monitoring of the change of sepsis severity (3). This assay is neither suitable nor intended for other applications and/or uses.
All measurements with EDTA whole blood samples collected from 100 apparently healthy individuals were found as < 0.3 μg/L for the IB10 sphingotest® PCT.
|< 0.5||Local bacterial infection is possible. Systemic infection (sepsis) is not likely.|
Low risk for progression to severe systemic infection (severe sepsis).
|Levels below 0.5 μg/L do not exclude an infection, because localized infections (without systemic signs) may be associated with such low levels.|
|≥ 0.5 and ≤ 2||Systemic infection (sepsis) is possible, but various conditions are known to induce PCT as well.|
|Moderate risk for progression to severe systemic infection (severe sepsis). The patient should be closely|
monitored both clinically and by re-assessing PCT within 6-24 hours.
|> 2 and ≤ 10||Systemic infection (sepsis) is likely, unless other causes are known.|
|High risk for progression to severe systemic infection (severe sepsis).|
|> 10||Important systemic inflammatory response, almost exclusively due to severe bacterial sepsis or septic shock.|
|High likelihood of severe sepsis or septic shock.|
