Abstract
In a method of measuring erythrocyte sedimentation rate of the type wherein the upper level of a blood sample contained in a vertical test tube is detected by a photoelectric detection unit, the red blood corpuscles are caused to precipitate for a definite interval and the upper level of the precipitated red blood corpuscles is detected by descending the photoelectric detection unit along the test tube thereby detecting the rate of the sedimentation of red blood corpuscles, the photoelectric detection unit is stopped at a position a small distance corresponding to the air bubble or coagulated substance from the upper level. The photoelectric detection unit is descended after said definite interval for detecting the interface between the blood serum and the precipitated red blood corpuscles. The rate of the sedimentation of the red blood corpuscles is determined in terms of the difference between the position at which the photosensitive detection unit has stopped and the position thereof a predetermined time after detection of the interface.
