Abstract
A stable lyophilized Hb control was prepared from human erythrocytes by removing stroma with Ca and Ficoll. Addition of polyhydroxy compounds enhanced reconstitution and stability. The lyophilized product was stable during 1 yr of use in a service laboratory. Accelerated aging studies demonstrated the potential of up to 2 yr of stability, with metHb increasing at a projected rate of .apprx. 6%/yr. Reconstituted, the control gave reproducible values for at least 5 days when refrigerated.
