Phagocytosis of human blood leukocytes: a simple micromethod

A simple micromethod for testing human blood leukocyte phagocytosis employing synthetic hydrophilic particles based on 2-hydroxyethylmethacrylate is described. The normal level of phagocytosing leukocytes in healthy children was 20.1 +/- 2.7%, and in healthy adult donors 34.3 +/- 6.1%. The method was found suitable for routine testing in both clinical and laboratory practice.
