  • Look Inside

The standard method for the diagnosis of infections is cultivation or direct detection of pathogen antigens. However, the cultivation test is time-consuming. In addition there are some pathogens whose growth is difficult or impossible to detect and there is a limit to detecting antigens of many pathogens. At present the detection of the pathogen antibodies or genes and microscopic examination of test specimens are used for the diagnosis of infections. The present paper describes test methods other than the above-mentioned methods that assist in the diagnosis of infections. CRP, PCT and cytokines are proteins that respond to the pathogens and are produced in vivo in the patients. These proteins are available as markers for inflammatory disease but not available as a single test item in making the diagnosis of infections. On the other hand, the causative microorganisms can be presumed to some extent by near-cutoff values of endotoxin or 1,3-β-D-glucan which were structural components of pathogens. It is essential for the exact diagnosis of infections to grasp the pathological condition of patients and to detect the pathogens at the same time in any of the subjects.
