The European Commission is working with Alere Inc., of Waltham, Mass., on the divestitures required for its acquisition by Chicago-based Abbott. As part of that, the terms have been revised on an Alere deal with Quidel Corp. Now, the San Diego-based Quidel will assume direct commercial responsibility for Alere's B-type Naturietic Peptide (BNP) assay business that runs on Beckman Coulter analyzers.
