A hemostatic article, e.g., a sponge is pretreated with predetermined quantities of selected hemostatic agents to assist hemostasis in surgical or traumatic wounds. The hemostatic article is provided with a visible marking/indication of the strength of the hemostatic agent. The visible indication may be color coding, or, the marking could take the form 20%, 40%, 60% and, 80%. The hemostatic agent may be any substance assisting in hemostasis, may be in powder or fluid form, and may be one or more of Thrombin, Gelform, Fibrinogen, or other hemostatic substances. The hemostatic article could include at least one radio-opaque element which may take the form of a thread or a strip. Alternatively, a radio chip embedded in the hemostatic article may be used. The visible markings per se could be made radio-opaque, thereby obviating a separate radio-opaque element. The pretreated marked hemostatic articles are sterilized for medical use in any known manner.
