Spot test: new technologies bring point-of-care testing into the 21st century (2009)
Journal Article
Luxton, R. W., & Kiely, J. (2009). Spot test: new technologies bring point-of-care testing into the 21st century

Every new technology offers the potential to effect changes in practise; many developments driven by the world-wide demand for instant results. This is never as true as in the arena of diagnostic testing. Once the sole preserve of the hospital labo...
