The GloCyte CSF cell counter by Advanced Instruments, Norwood, Mass, offers a new approach to CSF cell counting.

The automated instrument uses a combination of fluorescence imaging and a unique sample cartridge.

A laser excites the stained cells to fluoresce.

In the GloCyte procedure for counting CSF cells, stained sample is deposited onto a disposable cartridge and vacuum is applied to accelerate the capturing of cells. A laser excites the stained cells, causing them to fluoresce.

An intelligent algorithm provides accurate cell counts.

An intelligent algorithm provides accurate cell counts.

The cells captured in the cartridge are then imaged and enumerated by the automated cell counter, using an intelligent algorithm that ensures accurate cell counts.
