[Immunoradiometric determination of blood/tissue plasminogen activators in thrombophilia]

Immunoradiometric determination of the blood/tissue plasminogen activator was in plasma from patients before and after response to venous occlusion, infusion of DDAVP or exercise. The raise in the level of plasminogen activator was most pronounced after venous occlusion. In patients who earlier had had verified thrombosis the levels of plasminogen activator compared to normals did not show any significant difference.
