Description:

  • The Mitogen Stimulation Study is used in the evaluation of immunodeficiency to determine the functional capabilities of peripheral blood mononuclear cells to respond to non-specific stimuli (PHA and/or anti-CD3).
  • The Antigen Stimulation Study is used in the evaluation of immunodeficiency to determine the functional capabilities of peripheral blood mononuclear cells to respond to specific stimuli (Tetanus and/or Candida).
