The Government intends to award a Sole Source Purchase Order to assess the reproducibility of QFT-GIT results when the volume of the blood specimen used is both within- and out-of-range per the FDA approved package insert which allows a specimen range of 1.0 ml - 0.2ml. The specimen volumes to be used per test subject collected at a single point in time are 0.5ml, 0.8ml, 1.0ml, 1.0ml, 1.0ml, 1.2ml, and 1.5ml. The objective is to assess the degree of discordance in QFT-GIT results across specimen volumes and to identify conditions under which discordance may be expected. The contractor shall also measure inter-assay agreement in QFT-GIT results when the test antigens are mixed with the whole blood specimens using two different mixing conditions: a. Whole blood specimens shall be mixed with the antigens by shaking to the point at which the blood begins to froth - this procedure is recommended by the QFT-GIT manufacturer and has been FDA approved. b. Whole blood specimens shall be mixed with the antigens by rolling on a mixing platform (concurrently rocks and rolls tubes to assure full surface coverage) - this procedure is more consistent with the way phlebotomists are taught to handle blood specimens.
