Alternate Names : Anergy Panel, Anergy Screen

Why is the Test Performed?
This test is helpful in determining if a person's immune system is functioning properly. A skin test might indicate no exposure to a particular antigen (i.e., a false negative) when actually the immune system is unable to react to any antigen. An example of this would be a PPD or Tine test for tuberculosis, which might be falsely negative if a patients immune system is suppressed.
