PCT, known as procalcitoninogen, is a protein that can be used as an indicator of inflammatory response. Its level increases rapidly when there is a stress response such as inflammation in the body, and it has become one of the indicators of acute infections, bacterial infections and the degree of inflammation. In medicine, PCT is a biomarker measurement tool that can be used as a measure of acute infection, reflecting the degree of infection and thus guiding the development of clinical treatment programs.
Currently, the main method of detecting PCT is in vitro immunoluminescence assay, in which serum samples can be used to directly detect the level of PCT, which is highly accurate in clinical practice, and has high sensitivity and specificity for infection. Its normal level is generally below 0.1 μg / L, and the level will rise rapidly when an inflammatory response such as infection occurs. Therefore, for clinical treatment, detection of PCT levels in patient blood samples is one of the crucial tools in the identification and analysis of infections.
PCT is of great value in medical practice. PCT plays an important role in the prediction of acute and bacterial infection regression, screening for severe infections, timing of antibiotic use, disease diagnosis, and treatment monitoring. In clinical diagnosis and treatment, PCT, as an indicator with high sensitivity and specificity, has been widely noticed and emphasized in the screening, diagnosis, differential diagnosis and treatment monitoring of many infectious diseases, shock and organ failure. At the same time, the results of PCT can also be used to formulate scientific and reasonable medication programs, save medical resources, and improve the therapeutic effect. Therefore, the clinical application of PCT is very promising.
