Is fibrinogen determination by prothrombine time derived method confidant?

Elevated plasma fibrinogen (Fbg) levels have been shown, to be a risk factor for thrombotic events and cardiovascular disease. Currently, Fbg concentration is measured by Clauss and the prothrombine-time derived method. Despite of the derived method is simple and rapid, several studies have suggeste...
