title: In vitro granulocyte aggregation.
abstract: Granulocyte aggregation in EDTA-blood from a patient with rheumatoid arthritis is described. The phenomenon was observed three times within a 10-month period. The blood leukocyte count in a Coulter Counter decreased approximately 30% within 6 h, without resulting in overt leukopenia. Simultaneously, increasing numbers of granulocyte aggregates turned up in smears. There were no indications of thrombocytes being involved in the phenomenon.
