Anti‐N‐Like and Anti‐Form Red Cell Antibodies in Chronic Hemodialysis Patients

Anti N antibody in a patient of renal failure on hemodialysis

Anti N is a rare antibody. It has been reported in renal failure patients on hemodialysis using formaldehyde sterilized equipment. Although anti N is usually clinically insignificant, rarely it can cause hemolytic transfusion reaction. Patients with clinically significant antibodies should receive N antigen negative red cell units. We report a case of anti N antibody active at 37 °C in a patient of chronic renal failure on regular maintenance hemodialysis. The present case is being reported mainly because of its detection during routine blood grouping and compatibility testing by tube method in a patient of chronic renal failure on regular maintenance hemodialysis.
