Abstract
Oxidative sensitivity, measured by a modified ascorbate cyanide test, GSH and 51 Cr-RBC cytotoxicity, was abnormal before the haemodialysis.

All are indicative of RBC scavenger function against toxic oxygen radical production in dialysis patients. Despite this abnormality, erythrocyte deformability was completely normal.
