An instrument and a method for determining a characteristic of a biological fluid or control comprise providing a radiation-reflective surface, a source for irradiating the surface, a detector for detecting radiation reflected from the surface, and a cuvette for holding a sample of the biological fluid or control. The cuvette has two opposed walls substantially transparent to the source radiation and reflected radiation. The source and detector are disposed adjacent a first one of the two opposed walls and the radiation reflective surface is disposed adjacent the other wall. The method comprises detecting radiation from the source reflected from the surface using the radiation detector to determine a characteristic of the biological fluid or control.

[ What is claimed is:] [1.] In combination, an instrument for determining a characteristic of a biological fluid or a control, the instrument comprising a radiation-reflective surface, a first source for irradiating the surface, and a first detector for detecting radiation reflected from the surface
[ What is claimed is:] [1.] In combination, an instrument for determining a characteristic of a biological fluid or a control, the instrument comprising a radiation-reflective surface, a first source for irradiating the surface, and a first detector for detecting radiation reflected from the surface, means for determining the characteristic based on the reflected radiation, a cuvette for holding a sample of the biological fluid or control the characteristic of which is to be determined, the cuvette having two opposed walls substantially transparent to the source radiation and reflected radiation, the first source and first detector being disposed adjacent a first one of said two opposed walls and the radiation reflective surface being disposed adjacent a second of said two opposed walls, a second source for irradiating the surface, the first detector detecting radiation from the second source reflected from the surface, the second source positioned to transmit radiation through said two opposed walls for reflection by the surface and transmission back through said two opposed walls to the first detector to indicate whether a sample has reached a first point in the cuvette, the cuvette comprising a region for bearing a code, the instrument further comprising radiation source means for irradiating the code bearing region, detector means for detecting the transmission of radiation through the code bearing region, the radiation source means and detector means mounted adjacent the code bearing region to detect the code, a heater for maintaining the biological fluid or control at a desired temperature, means for mounting the heater adjacent the surface, means for providing power to the heater and means for monitoring the surface temperature and for feeding the monitored temperature back to the means for providing power to the heater, the heater comprising an electrically resistive foil, the surface comprising a first radiation reflective surface of a tile, the tile further comprising a second surface opposite the first surface thereof, and means for mounting the electrically resistive foil to the second surface of the tile.
