Test results are available within 10 to 20 minutes. ELISA (enzyme-linked immunosorbent assay) is a simple test that can be done in most veterinary laboratories and clinics. Enzymes that HIV uses in the process of infection: p31, p51, p66įeline immunodeficiency virus (FIV) is a lentivirus that causes an immunodeficiency syndrome in cats and is structurally similar to the human immunodeficiency virus (HIV).ĭiagnosis of FIV requires an FIV antibody test.Proteins from the core of the virus: p17, p24, p55.Proteins from the HIV envelope: gp41, and gp120/gp160.Western blot HIV tests usually look for antibodies against the following HIV proteins: And an enzyme is added to cause color changes that signal the presence of HIV antibodies. In the Western blot test, the sample is separated with an electrical current and transferred onto a piece of blotting paper. However, since 2014, CDC have recommended discontinuing the Western blot test for HIV, as other tests are now more reliable and enable a faster diagnosis. Western Blot is the benchmark test for confirming a diagnosed HIV infection followed by the ELISA test. The HIV-1 group M viruses predominate and are responsible for the AIDS pandemic. HIV-1 viruses may be further divided into groups. HIV-2 is related to viruses found in sooty mangabeys. HIV-1 is related to viruses found in chimpanzees and gorillas living in western Africa. Human Immunodeficiency Virus (HIV) can be divided into two major types, HIV type 1 (HIV-1) and HIV type 2 (HIV-2). The initial ELISA test has a sensitivity of about 70%, and in two-tiered testing, the overall sensitivity is only 64%, although this rises to 100% in the subset of people with disseminated symptoms, such as arthritis. Studies show the Western blot IgM has a specificity of 94–96% for patients with clinical symptoms of early Lyme disease. The reliability of testing in diagnosis remains controversial. Centers for Disease Control and Prevention (CDC) recommends a two-tier protocol using an enzyme-linked immunosorbent assay or Immunofluorescence Assay (IFA) initially, followed by the more specific Western blot to confirm the diagnosis when the assay samples are positive or equivocal. A history of confirmed exposure to tick bites, typical signs and symptoms of Lyme borreliosis and positive tests for anti-Bb antibodies, are the basis of a diagnosis. Lyme disease is a multi-organ animal-borne disease, caused by spirochetes of Borrelia burgdorferi (Bb), which typically affect the skin, nervous system, musculoskeletal system and heart.
