【Abstract】 Objective To formulate a simple and effective internal quality control modality using Objectives: This study aims to establish a quality control( QC) strategy based on a minimun number of off-market/self-made materials/reagent and evaluates its performance in real-life applications. Methods A set of quality control materials consisted of A/Rh D-negative RBC suspension( Ctrl 1),B/Rh D-positive RBC suspension( Ctrl 2),and AB plasma( Ctrl 3) were made from donated blood,among which,Ctrl 1 and 2 were stored in a preservation solution while C were processed by an Ig G anti-D reagent. In Ctrl 1 and 2,erythrocytes,plasma and the erythrocyte preserving fluid were mixed at a ratio of 1 ∶2 ∶4. In Ctrl 3,Ig G anti-D was added to the AB plasma at a ratio of 1 ∶256. Ctrl 1 and Ctrl 2 were applied for the in-door quality control of blood group typing. Ctrl 2 and Ctrl 3 were designed for antibody screening tests. Ctrl 1,Ctrl 2 and Ctrl 3 combined manipulated the roles of donors or recipients in the crossing matching,respectively. Performance evaluations were conducted considering the following criteria: homogeneity,stability,and effectiveness. Results Ctrl 1 were A/Rh D-negative while Ctrl 2 were B/Rh D-positive. Antibody screening tests of Ctrl 2 and Ctrl 3 were negative and positive,respectively. In the crossmatching tests,the major crossmatch of Ctrl 1( as recipient) and Ctrl 2( as donor),Ctrl 2( as donor) and Ctrl 3( as recipient),Ctrl 1( as donor) and Ctrl 3( as recipient) resulted in incompatibility( 4 +),incompatibility( 2 +) and compatibility,respectively. The RBC suspension can be stored at 4℃ for 6 months as the antibody titer and erythrocyte antigens of the suspension remained stable. Ctrl 3 can be kept in-20 ℃ for storage to maintain a bio-functional Ig G anti-D antibody titer. Each of the control materials scored CV< 10% in stability testing. Conclusion Our in-door QC strategy with self-made/off-market QC materials showed promising homogeneity,stability,and effectiveness.更多还原
