A fully automated immuno-turbidimetric determination of fibrin(ogen) degradation products

A fully automated procedure for the determination of fibrin(ogen) degradation products was developed using the I. L. Multistat Centrifugal Analyzer (MCA). The assay is based on the turbidometric measurement of the interaction between antibodies to human fibrinogen and defibrinogenated specimens. The method allows, with high reproducibility, for the accurate quantitation of degradation products between 10 and 160 micrograms/ml. A comparative study of 100 normal and abnormal patient samples revealed an excellent correlation with the semi-quantitative manual procedure. The method can be adapted to existing automated coagulation procedures and can become part of coagulation panels.
