Monoclonal antibody-based plasma assays for fibrin(ogen) and derivatives, and their clinical relevance

Abstract

The haemostatic balance can basically be described as the equilibrium between fibrin formation (coagulation) and fibrin lysis (fibrinolysis). The status of this balance may therefore be reflected by the products of these two processes. Until recently, the tests for assessment of fibrin(ogen) degradation products were performed in serum since they were based on polyclonal antibodies, which cross-react with fibrinogen. However, the use of serum introduces many artefacts so the utility of these serum tests is limited. New assays have now become available, which can be divided into quantitative enzyme immunoassays (EIAs) and semi-quantitative latex agglutination assays. The new assays can be carried out in plasma since they use highly specific monoclonal antibodies, the majority of which do not cross-react with fibrinogen. This makes it possible to avoid the serum artefacts. Furthermore, these plasma assays can discriminate between degradation products of fibrin and those of fibrinogen (FbDPs and FgDPs, respectively). The possible clinical utility of the new assays is discussed on the basis of literature data on the following clinical states: deep venous thrombosis (DVT) and pulmonary embolism, liver disease and liver transplantati...Continue Reading

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
