Laboratory Algorithm in HIV Infection Diagnosis

AIDS caused by HIV is an infection disease which was defined firstly in the USA in 1981. Since then, number of AIDS patients has increased continuously. About 36.9 million people are living with HIV around the world. Approximately 15 million people living with HIV were receiving antiretroviral therapy. Early detection is important due to the high risk of transmission that precedes seroconversion and also because it provides an opportunity to improve health outcomes with an early antiretroviral therapy. HIV testing is the key part of diagnosis and prevention efforts.
