Procalcitonin (PCT) is a procalcitonin glycoprotein without hormone activity. The half-life of PCT is 25-30 hours, and it is very stable in vivo and in vitro. The plasma PCT content of healthy people is extremely low. During bacterial infection, in addition to the thyroid, macrophages and monocytes in the liver, lymphocytes and endocrine cells in the lung and intestinal tissues can synthesize and secrete PCT. At this time, the serum PCT level will increase significantly, and the infection progresses Or control and continue at a high level or gradually decline, not affected by the body's immune suppression state. For bacterial infection/sepsis, PCT is currently the best biological indicator.
