✦ Synopsis

Graphical representation of laboratory data speeds up recognition of abnormalities. The Chernoff face is an excellent tool to represent patient data; the human eye and mind are exquisitely sensitive to subtle changes in facial appearances and expression. One of the best uses of the faces is in illustrating Kev words: trends in the data, particularly in acutely ill patients where many laboratory studies are performed. The faces are especially useful if comparisions to a former or normal state are made. A very brief examination of adjacent faces suffices to identify changes in laboratorydata.
