For Assessing Risk Over Time
In the ICU, in the Emergency Department, in patient wards — VIDAS® B•R•A•H•M•S PCT™ (Procalcitonin) can aid in sepsis risk assessment and deliver key data related to bacterial infection severity, at initial presentation and over the course of treatment. In managing critically ill patients, serial measurements over multiple days can support assessment of that patient’s response to therapy. As the infection is controlled, PCT will decline daily.1
DEMONSTRATED IN A MAJOR STUDY2
The Procalcitonin Monitoring Sepsis Study
- 858 adult patients with sepsis recruited across 13 investigational sites in the United States
- The mortality rate was 2-fold higher when PCT did not drop by more than 80 percent from baseline to Day 4
- The initial PCT level (<— 2.0 ng/mL or > 2.0 ng/mL) provided important additional information about the mortality risk when evaluating the patient’s clinical course with PCT measurements on subsequent days
The change of PCT over time aids in assessing the cumulative 28-day risk of all-cause mortality for patients diagnosed with severe sepsis or septic shock.
It's Different from Other Biomarkers
- PCT is distinguished from other markers by its early and highly specific increase in response to severe systemic bacterial infections and sepsis3,4
- Increased PCT levels can be observed within just 3–6 hours after an infectious challenge5
- With a 24-hour half-life, PCT decline is consistent with an improving clinical condition3,5
Unique Kinetics of PCT Are Strong Indicators of Mortality Risk Over Time2
Assessing PCT kinetics over time provides valuable information regarding patient disposition, response to treatment and likelihood of survival
