A team from Caltech and MIT, USA, and LeukoDx, Israel, have combined a microflow cytometer and fluorescent dye to produce a portable suitcase-sized point-of-care test for leukocyte count – one of the most common clinical tests. The test can identify four different types of leukocyte using only a small blood sample.

A technical innovation from Oliver Hayden and Michael Helou et al. in Germany featured on the outside front cover of Issue 6 also concentrates on flow cytometry for point-of-care testing. This vastly different technique uses magnetophoresis instead of fluorescence to detect specific cancer cells in whole blood. Cell diameters are measured from time of flight information. The device integrates sample preparation for ease of point-of-care applications. The can perform cell enrichment, cell focusing and background elimination in situ.
