The treatment of aggressive diseases often benefits very noticeably from combination therapy, especially when involving the immune system. In fact, one often-cited combination therapy is HAART: Highly Active Antiretroviral Therapy used in the treatment of HIV. With six major types of drugs being used in this combination therapy, each slows or disrupts the replication of HIV cells in different ways.
1 Combination tests have been developed that detect HIV antibody and the HIV antigen called the p24 antigen. 2  Levels of p24 antigen are typically high early in the course of infection. 3  A combination test may be performed to increase the likelihood that HIV infection is detected sooner after exposure occurs.ifferent types of antibody tests may be used for HIV screening: 1  All HIV tests used in the U.S. detect HIV-1, and some tests have been developed that can also detect HIV-2.
