Abstract
Methods are disclosed for analysing the concentration of red blood cells in a flow of blood including flowing the blood through a cuvette, directing a light through the flow of blood, measuring light transmitted through the flow of blood to obtain a transmitted signal, measuring scattered light at a predetermined angle with respect to the direct transmission path through the flow of blood to obtain a scattered signal, and providing a ratio signal comprising the ratio between the scattered signal and the transmitted signal. Apparatus for analysing the concentration of red blood cells is also disclosed.
