The present invention is drawn to concentrated fibrinogen compositions and associate methods and use thereof. The concentrated fibrinogen compositions can be produced by adding a sufficient amount of a cationic agent, such as protamine, to a fibrinogen containing fluid to cause the fibrinogen to form a fibrinogen precipitate; collecting the fibrinogen precipitate by a collection means, such as centrifugation; and suspending or solubilizing the fibrinogen precipitate in a liquid vehicle to form a concentrated fibrinogen composition. The concentrated fibrinogen compositions can be incorporated into systems for making fibrin glues and be used in treating wounds.
