The level of procalcitonin rises in a response to a pro-inflammatory stimulus, especially of bacterial origin. It is therefore often classed as an acute phase reactant . [ 4 ] The induction period for procalcitonin ranges from 4–12 hours with a half-life spanning anywhere from 22–35 hours. [ 5 ]
The authors suggested that procalcitonin may serve as a helpful diagnostic marker for sepsis, but cautioned that its level alone does not definitively make the diagnosis. [45] More current literature recommends utilizing the PCT to direct antibiotic therapy for improved antibiotic stewardship and better patient outcomes.
For most substances presented, the optimal levels are the ones normally found in the population as well. More specifically, optimal levels are generally close to a central tendency of the values found in the population. However, usual and optimal levels may differ substantially, most notably among vitamins and blood lipids, so these tables give ...
[11] [better source needed] In untreated coeliac disease, concentration levels of faecal calprotectin correlate with the degree of intestinal mucosal lesion and normalize with a gluten-free diet. [6] High fecal calprotectin is a common finding among hospitalized coronavirus disease 2019 ( COVID-19 ) patients, especially those with SARS-CoV-2 ...
Increased levels of calcitonin have also been reported for various other conditions. They include: C-cell hyperplasia , nonthyroidal oat cell carcinoma, nonthyroidal carcinoma and other nonthyroidal malignancies, acute kidney injury and chronic kidney failure , hypercalcemia , hypergastrinemia , and other gastrointestinal disorders, and ...
-->Kidney disease Procalcitonin can be dialyzed, and so levels are dependent upon when patients receive will be affected after hemodialysis. -->Septic arthritis PCT, at a cutoff value of .5 ng/mL, was effective at ruling in septic arthritis in an analysis of over 8000 patients across 10 prospective studies.
Possible predictors of severe and fatal cases may include lymphopenia, thrombocytopenia and high levels of ferritin, D-dimer, aspartate aminotransferase, lactate dehydrogenase, C-reactive protein, neutrophils, procalcitonin and creatinine as well as interleukin-6 (IL-6). Ferritin and IL-6 are considered to be possible immunological biomarkers ...
