Method and composition for detecting fibrin monomers and fibrin degradation products

摘要

A method for detecting fibrin and fibrin degradation products in blood plasma which involves mixing the blood sample with a composition containing protamine sulfate and finely divided colored particles and visually observing the resultant colored fibrin strands and colored fibrin gels in a positive test. The composition is prepared by gradually adding a saline solution of the colored particles to a saline solution of the protamine sulfate and the pH is adjusted to 6.5 +/- 0.05.
