HIV and AIDS

Of the more than 35.3 million people worldwide infected with HIV, only about 11.7 million have access to treatment (2013)*. The WHO goal is to increase that number to 15 million by 2015. According to the WHO 2013 guidelines, close to 26 million people are eligible for antiretroviral therapy (ART). As diagnostics, therapies, and healthcare infrastructure become more accessible, estimating CD4 lymphocyte counts guides initiation of ART and 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.
