Calypte Only Company with Full Menu of Tests.

Calypte Biomedical Corporation (http://www.calypte.com) is a U.S.-based healthcare company focused on the development and commercialization of diagnostic testing products for the detection of sexually transmitted diseases such as the HIV-1 BED Incidence EIA and new diagnostic test products for the rapid detection of HIV and other sexually transmitted diseases, several of which do not require blood samples. Calypte believes there is a significant need for rapid detection of such diseases globally to control their proliferation, particularly in developing countries, which lack the medical infrastructure to support laboratory-based testing. Calypte believes that testing for HIV and other sexually transmitted infectious diseases may make important contributions to public health, and could increase the likelihood of treating those with undetected HIV and other sexually transmitted diseases.
