ID:935 Procalcitonin
Search Links: General Info : Protocols : LabTestsOnline

DescriptionProcalcitonin is a precursor to the hormone calcitonin, a relatively specific marker for severe bacterial infection in patients with suspected sepsis. ****PLEASE NOTE - This test is only offered to a specific cohort of patients as part of a study. Requests from other areas will NOT be processed ****
Indication
Additional InfoProcalcitonin is normally produced by the parafollicular cells of the thyroid but can also be produced by the neuroendocrine cellls of the lung and the intestine in response to proinflammatory stimuli. Elevated procalcitonin concentrations occur in systemic bacterial infections. Relatively low concentrations are seen with viral infections or inflammatory diseases. Procalcitonin is more sensitive than CRP in discriminating between bacterial and viral infections. Low procalcitonin predicts the absence of bacteraemia/sepsis. An increase in procalcitonin, in response to infection occurs before a rise in CRP.
