About Calypte Biomedical:

Calypte Biomedical Corporation is a US-based healthcare company focused on the development and commercialization of diagnostic testing products for the detection of sexually transmitted diseases. Calypte specializes in novel tests such as the HIV-1 BED Incidence EIA and is engaged in developing and commercializing 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 that there is a significant need for rapid detection of such diseases globally to control their proliferation, particularly in lesser-developed 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.
