Transfusing selected <scp>RhD</scp> negative patients with <scp>RhD</scp> positive packed red cell concentrates resulted in lower frequency of anti‐D development and saved almost two thousand <scp>RhD</scp> negative concentrates during 5 years

The proportion of anti-D immunisation in RhD negative patients receiving RhD positive PRBCCs in this study was consistent with findings from other reports. To our knowledge, this is the first study reporting a high proportion of evanescence of anti-D. Transfusing selected RhD negative patients with RhD positive PRBCCs when RhD negative stocks are low, contributed saving 1926 RhD negative PRBCCs during the study period of 64 months.
