Methods for determining a function of cells, which comprises a suspension of cells flowing along a first fluid channel. The cells have a first detectable property associated therewith, and wherein the cells produce a second detectable property upon activation of the function of the cells, the first and second detectable properties being distinguishable from each other. Levels of the first and second detectable properties are measured. The level of the second detectable property is compared to the level of first detectable property to determine the relative function of the cells. |
