What is a procalcitonin test?A procalcitonin test measures the level of procalcitonin in your blood. A high level could be a sign of a serious bacterial infection, such as sepsis. Sepsis is the body's severe response to infection. Sepsis happens when an infection in one area of your body, such as your skin or urinary tract, spreads into your bloodstream. This triggers an extreme immune reaction. It can cause a rapid heartbeat, shortness of breath, decreased blood pressure, and other symptoms. Without quick treatment, sepsis can lead to organ failure or even death.A procalcitonin test can help your health care provider determine if you have sepsis or another serious bacterial infection in the early stages. This may help you get treated promptly and avoid life-threatening complications.Other names: PCT test
