Piece de resistance
Executive Summary
HIV resistance testing will soon be the standard of care in the treatment of AIDS, many bet, foremost among them Visible Genetics Inc., Innogenetics NV, PE Biosystems Group and Roche Molecular Systems Inc., all of which are developing genotyping tests to look for genetic mutations in HIV that are known to be resistant to particular drugs. Genotyping is not the only way to assess HIV drug resistance, and two developers of phenotyping resistance tests, ViroLogic Inc. and Virco Group hope to stake a claim in this developing market as well.
