Comments:

Since the assay is run on Tuesday only, the blood must be drawn on 
Tuesday.  Do not centrifuge.  This assay is run using viable 
lymphocytes.  Have floor deliver to Cellular Immunology Lab, VAMC Bldg. 
41, Room 223 or Specimen Control (6240 RCP) within 3 hours of drawing.  
Must be in lab no later than noon.  Test may also be run on Friday, but 
prior arrangements (1-2 day advance notice) are required. Call 
158-7550.  This assay is designed to examine whether a patient has 
activated lymphocytes in the circulation.  If interested in knowing the 
functional responsiveness of a patient's T lymphocytes, 'Lymphocyte 
Tranformation, Antigen' and 'Lymphocyte Tranformation, Mitogen' should 
be ordered.
