Lymphocyte switching test

When T cells are cultured in vitro, stimulated by non-specific mitogens (such as phytohemagglutinin Phytohemagglutimin (PHA)) or specific antigens, cell volume increases, metabolism is vigorous, protein and nucleic acid synthesis increases, and they can divide into Lymphocytes are the phenomenon of lymphocyte switching. The level of lymphocyte transformation can reflect the body's cellular immune level. Therefore, the lymphocyte conversion test can be used as one of the indicators to determine the body's immune function.
