A method and apparatus for measuring the coagulation properties of blood, a blood fraction, or a control fluid are provided. The system includes a surface for reflecting radiation, a first radiation source for emitting to the surface, and a first detector for detecting radiation reflected from the surface. The cuvette 101 holds a sample 514 comprising the blood, blood fraction, or control solution whose coagulation properties are to be measured. The cuvette 101 has two opposing walls 506, 508 that are substantially transparent to radiation from the radiation source 244 and reflected radiation. The first radiation source 244 and the first detector 242 are disposed adjacent to a first wall 508 of the two opposing walls 506, 508, and the radiation reflecting surface 194 includes Two opposing walls 506, 508 are disposed adjacent to a second wall 506.
