Description

In vitro medical diagnostic device used fot the determination of Thrombin time. The reagent can be used manually or on semi-automated and automated instruments. The test is commonly applied to detect various sources of interference with normal blood coagulation. Prolongation of the Thrombin clotting time can be taken as a qualitative indication of abnormal Fibrinogen levels (high or low), or the presence of interfering substances such as FDP?s or Heparin. Quantitative evaluation of the possible causes of prolonged Thrombin Time should be performed as follow-up studies, such as aPTT or chromogenic assay for Heparin, Clauss fibrinogen, FDdeterminations, heparin neutralisation by protamine sulphate or polybrene, normal plasma mixing studies or Reptilase assay to distinguish between hypofibrinogenaemia and FDP effects.
