>> since the clinical lab structure started to develop we've had this highly centralized very big analytical instruments which require that much blood and therefore people have had to take tubes and tubes every time they do a blood draw. so laboratory testing hasn't changed since the 1950s. it's the closest thing to mainframe computers versus -- it's not even pcs. versus mobile phones that i've ever seen. so the timing is very ripe to change this paradigm. ♪
