HIV and AIDS

Of the more than 33 million people worldwide infected with HIV, only about 3 million are currently treated.* The WHO goal is to increase that number to 10 million by 2010. As diagnostics, therapies, and healthcare infrastructure become more accessible, estimating CD4 lymphocyte counts becomes a critical link in monitoring HIV infection and disease progression.


BD Biosciences instruments and reagents are used in CD4 testing. The BD FACSCount™ system is used in developing areas of the world where easy-to-use systems are needed. The BD FACSCalibur™ system is used in high-volume labs in resource-limited settings, and the BD FACSCanto™ II system is used for HIV monitoring and other applications when more sophisticated technologies are required.
