Lymphocyte Function Testing in Immuno-oncology

"The functional assessment of T lymphocytes is based on the use of the VIDAS® STIMM™ T RUO test, which will be performed on freshly collected whole blood in lithium heparin tubes without gel separators. Blood samples will be sent to the Immunology Laboratory at E. Herriot Hospital (Prof. Guillaume Monneret). T lymphocytes will be stimulated ex vivo for 3.5 hours (non-antigen-dependent stimulation by PHA) on the VIDAS®3 automated system (bioMérieux).~The automated system then performs a assay (immunofluorescence technique) to quantify the concentrations of IFN-γ in the supernatant of each sample. The entire process is automated, and results are obtained within 4 hours."
