levels of microparticle (MP) tissue factor (TF) activity in cancer patients with or without VTE.
Blood was collected from cancer patients within 24 h of objectively diagnosed VTE (n= 53)
and from cancer patients without VTE (n= 13). MPs were isolated from platelet poor plasma
by centrifugation at 20,000 g for 15 min. MP TF activity was measured using a two-stage
chromogenic assay. Cancer patients with VTE had a significantly higher mean MP TF activity …
