[Modified method of assessing spontaneous erythrocyte aggregation]

To prevent infection of the examinees via blood during venipuncture and to simplify the method for assessment of red cell spontaneous aggregation the authors have compared red cell aggregation in venous and capillary blood. Red cell aggregation coefficients assessed by various methods in blood samples collected from the finger and vein were virtually the same; hence, this characteristics can be investigated in a capillary blood sample.
