Comments:
This assay is run Monday through Thursday during working hours and Friday 8 a.m. to noon. This assay is run using viable lymphocytes.

This assay examines the ability of a patient's lymphocytes to generate IL2, and other cytokines, in response to a physiologic (via the T cell receptor complex) as well as a pharmacological stimulus. An abnormal response would suggest a T lymphocyte immune deficiency and would be consistent with a clinical picture of recurrent infection, failure to thrive and, possibly, recurrent tumors.
