Abstract: Background: CoaguChek XS is one of the most widely used point-of-care (POC) devices to evaluate prothrombin time for monitoring oral anticoagulant therapy. Unlike laboratory methods, it detects electrical signals produced by thrombin activity to derive the international normalized ratio (INR). Therefore, we hypothesized that laboratory methods and CoaguChek XS could produce different results according to fibrinogen level. Methods: We compared INR values obtained from the CoaguChek XS and conventional laborato…
