Additional information
Procalcitonin is normally produced by the parafollicular cells of the thyroid but can also be produced by the neuroendocrine cells 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.
