Principle Quantitative determination of fibrinogen is typical measurement, which is to determine diluted plasma clotting time after adding thrombin. In the coordinate illustration, thrombin time is proportional to the quantity of fibrinogen when there exist thrombin with high thickness and fibrinogen with low thickness.Clinical application It is intended for use in quantitative determination of fibrinogen , helping determine congenital and acquired fibrinogen deficiency (such as disseminated intravascular coagulation, liver disease, etc.)and monitoring thrombolytic therapy.Storage Liquid: It has a 2 year shelf life when stored at 20 unopened, and it can be stored at 2 8 for 30 days after opened. Lyophilized: It has a 2 year shelf life when stored at 2 8unopened , and it can be stored at 2 8 for 5 days after constitution.Packing Requirment Lyophilized : 1304002G 5×2ml(200T) 1304004G 5×4ml(400T) Liquid: 1304002Y 5×2ml(200T) 1304004Y 5×4ml(400T) 1304005Y 5×5ml(500T)
