The recovery of blood monocytes after centrifugation with metrizoate/polysucrose was high with EDTA (97.0%) and heparin (91.6%) as anticoagulants, moderate with EGTA and citrate, but low with oxalate (52.3%; P<0.05 compared with heparin). There were no differences in viability, spontaneous migration, chemotaxis, or phagocytosis and killing of Candida albicans by the monocytes isolated from blood anticoagulated with heparin, citrate, oxalate, EDTA, or EGTA. However, heparin in concentrations above 20 IU/ml decreased the spontaneous migration and chemotaxis. It is concluded, that EDTA and heparin below 20 IU/ml are the most satisfactory anticoagulants for the functional study of blood monocytes isolated by metrizoate/polysucrose density centrifugation.
