Cerebrospinal fluid examination of white blood cells 141, considering the existence of central system infection, the disease has individual variability for different patients, can not directly determine its severity, it is recommended that timely medical further examination and targeted treatment. Cerebrospinal fluid examination of normal white blood cell count is (0 to 5) × 10⁶ / L, mainly monocytes. Its elevation is commonly seen in infectious diseases of the central system, such as purulent meningitis, tuberculous meningitis, cryptococcal encephalitis, and so on. 1. Increased leukocytes are seen in inflammatory lesions of the cerebrospinal membrane and brain parenchyma. 2. Significantly increased leukocytes and predominantly multinucleated cells are seen in acute purulent meningitis. 3. Mild or moderate increase in leukocytes with monocytes predominating, seen in viral encephalitis. 4. A large number of lymphocytes or monocytes increase predominantly, mostly subacute or chronic infection. 5. In parasitic infections of the brain, more eosinophils are seen. Cerebrospinal fluid leukocyte count 141 is moderately increased, but also need to carry out cerebrospinal fluid culture to determine what kind of bacterial infection, to be bacterial culture results, and then according to the classification of the pathogenic bacteria to carry out the appropriate standardized treatment.
