[Comparative study of various rapid methods of determining fibrinogen transformation products in the diagnosis of intravascular coagulation and fibrinolysis].

Rapid methods for determination of fibrin-monomer complexes and fibrinogen/fibrin degradation products were studied and compared in 76 patients with different abnormalities in the hemostatic system (acute thromboses, thromboembolism of the pulmonary artery, disseminated intravascular coagulation, immune thrombovasculitis, etc). The control group consisted of 36 healthy donors. The fibrin-monomer complexes were determined by the paracoagulation tests, the ethanol test (ET) and protamin sulfate tests (PST), whereas fibrinogen/fibrin degradation products (FDP) by the staphylococcus adhesion test (SAT) in which use was made of the Newman D2S strain variety obtained by the authors. It is inferred that the ET, PST and SAT are the most suitable for use in clinical medicine, since they are accessible, simple and quick in performance. However, these tests cannot be regarded as similar or interchangeable, since they are used for studying different products of the coagulation and fibrinolytic transformation of fibrinogen.
