Abstract
An instrument for determining a characteristic of a biological fluid or a control includes a radiation-reflective surface, a first source for irradiating the surface, and a first detector for detecting radiation reflected from the surface. A cuvette for use with the instrument holds a sample of the biological fluid or control the characteristic of which is to be determined. The cuvette has two opposed walls substantially transparent to the source radiation and reflected radiation. The first source and first detector are disposed adjacent a first one of said two opposed walls and the radiation reflective surface is disposed adjacent a second of said two opposed walls.
