<unk>  <unk>  is a test used by pharmaceutical and biotech organizations to show the safety of a drug or implantable material. It is commonly used as part of the FDA clearance process. Put simply, it is mixing populations of T-lymphocytes (category of white blood cells) together, and measuring the<unk>  that occurs. Technically, it is an ex-vivo cellular immune assay that occurs between two allogeneic<unk>  populations (same species but genetically distinct). In a one-way<unk> , only one<unk>  population can respond or proliferate. In a two-way<unk> , both populations can proliferate.<unk> ’s are performed to assess how T-cells react to external stimuli. T cells are a type of white blood cell that scans for cellular abnormalities and infections. They are essential to human immunity.
