Optical Q - Immunoassay for the Quantitative Determination of PCT

Procalcitonin (PCT) is a substance produced by many types of cells in the body, often, and more significantly in response to bacterial infections and sepsis, but also in response to tissue injury and stress. Other stressors may include viral infections, trauma, surgery, pancreatitis, burns, shocks associated with cardiac arrest, and acute organ transplant rejection. PCT tests are conducted to detect the presence of a bacterial infection in its early stages and are also, in crucially ill patients, used to guide antibiotic treatment by differentiating between bacterial infections and other causes.
