A Procalcitonin (PCT) test is a specialized blood marker used primarily to detect and monitor severe bacterial infections and sepsis. While many markers (like CRP) indicate general inflammation, Procalcitonin is unique because it rises significantly in response to bacteria but remains low during viral infections.
This “specificity” makes it one of the most valuable tools in the Emergency Room and ICU for deciding whether a patient needs antibiotics.
