Commonly used immune function assessment indicators

Including the number of mononuclear macrophages, neutrophils, white killer cells, B lymphocytes, T lymphocytes. Blood routine white blood cell count is often used for basic immune status assessment, but white blood cells can reflect the state of bone marrow proliferation, and can not be used to assess the level of immunity, the absolute value of lymphocytes and the percentage of lymphocytes are the basic indicators to reflect the immune status, and continue to be less than 1.0 × 109/L, it is highly suggestive of abnormal immune status. The chemiluminescence intensity of polymorphonuclear leukocytes, that is, neutrophils, was significantly reduced in patients with sepsis, suggesting that the bactericidal activity of neutrophils was weakened.
