The present invention seeks to provide an express-control system for analyzing the compatibility of blood with other substances. The present invention relates to a system, method and apparatus for use in blood testing and more specifically, food intolerance testing through analysis of blood using luminescence. The present invention utilizes a blood testing system and apparatus, which includes a displacement assembly, a blood divider assembly, a reagent divider assembly, an electro-optical multiplier assembly and a central controller. A sample of blood is added to a corresponding one of a plurality of canisters containing a test substance. Thereafter a luminescent reagent is added and the plurality of canisters are moved in the blood testing apparatus until the canisters begin to luminese. The amount of luminescence is measured and analyzed an indicator of compatibility of the blood with the test substance and more specifically as an indicator of the presence and activity of neutrophil in the blood and more specifically the granulacy of the blood.
