Clinical Significance
The Fibtem® assay is a semi-quantitative in vitro diagnostic assay on the ROTEM® delta Thromboelastometry System to monitor the clot firmness of citrated whole blood specimens after blocking platelet contribution to the clot firmness. The fib-tem® reagent is always used in conjunction with ex-tem® reagent.
