Abstract
A method is proposed for the rapid estimation of plasma fibrinogen concentration. The technique depends on the increase of optical density occurring when plasma clots. A kit is described which obviates the use of laboratory apparatus, so that the test may be performed in the ward side-room if a small centrifuge can be provided.A calibration curve has been prepared for use with commercial opacity standards, and a measure of the error of the method has been obtained.
