Procalcitonin

Procalcitonin is a substance produced by the body in response to bacterial infections. When bacteria cause an infection, levels of procalcitonin in the blood increase, making it a useful marker for diagnosing bacterial infections and gauging their severity. It helps healthcare providers decide whether antibiotics are necessary and monitor treatment effectiveness. Procalcitonin levels typically remain low during viral infections or non-infectious conditions, aiding in accurate diagnosis. Overall, it is a valuable tool for guiding appropriate treatment and avoiding unnecessary antibiotic use.
