Maternal Anti-M: IWK Change in Laboratory Approach

The IWK Heath Centre Blood Bank, with the support of the Rh program of Nova Scotia, has recently changed the practice for pregnant patients with an anti-M antibody. This change is based on a case report and review of Japanese literature published in Transfusion Medicine Reviews in January 2014. Antibody screening every four weeks is now being recommended for anti-M antibodies.
