These containers can keep frozen specimens frozen, but they will not be able to freeze specimens at room temperature or refrigerated specimens. In response to the coagulation process the fibrinolytic system is activated resulting in the conversion of plasminogen into plasmin, which cleaves fibrin (and fibrinogen) into the fragments D and E. Due to cross-linkage between D-domains in the fibrin clot, the action of plasmin releases fibrin degradation products with cross-linked D-domains. You can do this quickly while the patient's arm is elevated. Turn the centrifuge off, if not an automatic turn off, and allow it to come to a complete stop.
