What can cause elevated procalcitonin?
What can cause elevated procalcitonin?
Severe trauma, major burns, multiorgan failure, or major surgery can cause procalcitonin (ProCT) elevations in the absence of sepsis. After removal of the noxious stimulus, ProCT should start to decrease.
When is procalcitonin elevated?
If your results show a high procalcitonin level, it’s likely you have a serious bacterial infection such as sepsis or meningitis. The higher the level, the more severe your infection may be. If you are being treated for an infection, decreasing or low procalcitonin levels can show that your treatment is working.
What is the normal range for procalcitonin?
Reference Range of Procalcitonin Procalcitonin arises from endopeptidase-cleaved preprocalcitonin. The reference value of PCT in adults and children older than 72 hours is 0.15 ng/mL or less. Reference values for PCT have not been established in infants younger than 72 hours.
How long does it take to get procalcitonin results?
Procalcitonin will be available 24 hours a day and will be run as needed. Stat order results will be available within 90 minutes while results of routine testing will be available during the same shift (usually 2-4 hours). A value of = 0.1 µg/L will be flagged as elevated.
How is procalcitonin used in the treatment of cap?
In an analysis of a subset of 2910 patients with CAP, the procalcitonin algorithm reduced antibiotic exposure by 2.9 days when compared with standard care (7.5 versus 10.4 days, 95% CI -2.02 to -2.87). There were no significant differences in mortality, treatment failure, length of stay, or antibiotic-associated side effects.
When to take procalcitonin for bacterial LRTI?
Recommended Use: Based upon this evidence it is suggested that patients considered at risk for bacterial LRTI or being started on antibiotics have a PCT value measure on admission and every 2-3 days subsequently. Interpretation of values is listed below in Algorithms 1 and 2.
Can a blood test show a low procalcitonin level?
Low Procalcitonin With Sepsis. It is possible for the test to show a low procalcitonin level in the very early stages of sepsis, but it will likely increase over the next few hours or days. By contrast, a person may have high levels in the early stages of sepsis but have no symptoms at all.
