In general, cerebrospinal fluid tests include routine cerebrospinal fluid, cerebrospinal fluid biochemistry, cerebrospinal fluid bacterial culture, and drug sensitivity tests. Of course, in some special cases, there are other tests, such as cryptococcal tests and syphilis spirochete fluorescent antibody uptake tests. First, for cerebrospinal fluid, physical examination is the visual observation of the general condition of the cerebrospinal fluid, including pressure, color, transparency, and coagulation. Next is the chemical examination of the cerebrospinal fluid, which includes electrolytes, chloride, glucose, acidity, and alkalinity. In addition some patients may have a cell count, for example, the total cell count can be clarified as well as the white blood cell count, and in more detail, the leukocyte sorting count. Finally, there are some pathogenic tests, such as bacteria and which antibiotics they are sensitive to, which can effectively guide the clinical use of drugs, or the presence of schistosomes and other conditions, which can effectively guide the clinical diagnosis. In summary, the cerebrospinal fluid examination includes routine, biochemical, and pathogenic tests, etc. These specific laboratory results require specific consultation with the physician, and combined with clinical manifestations, a comprehensive assessment.
