Accurate, low cost testing of donated blood is a goal of the global effort to reduce the spread of the human immunodeficiency virus (HIV‐1). We describe a modified enzyme immunoassay (EIA) method for detecting HIV‐1 antibody (anti‐HIV‐1) in 15‐sample pools. In this preliminary study, the modified EIA was as sensitive for detecting weakly seropositive samples, and as specific for testing HIV‐1 Western blot‐negative or Western blot‐indeterminate results, as testing individual samples by the standard EIA. A simulation of field operations was conducted using pools of blood donor samples collected in the United States and in Shanghai, People's Republic of China. Implementation of the modified EIA method and testing 15‐sample pools for anti‐HIV‐1 is a reliable strategy for reducing the cost of large scale testing of donated blood for anti‐HIV‐1 in areas of low seropre valence.
