HIV-1/HIV-2 Rapid Screen Does this test have other names? Rapid HIV antibody test. What is this test? This test looks for HIV infection in your blood or saliva.

The INSTI® HIV-1/HIV-2 Antibody Test is a rapid in vitro qualitative test for the detection of antibodies to Human Immunodeficiency Virus Type 1 and Type 2 in human … This test begins with HIV-1/-2 antigen and antibody screen by chemiluminescence immunoassay. If the screen result is reactive, then HIV-1/-2 antibody differentiation test by immunochromatographic method is performed at an additional charge. For use ONLY when patient has a repeatedly reactive third- or fourth-generation HIV screen test result.

If early/acute infection is suspected, testing by NAT (HIV-1 RNA Qualitative TMA) should be considered. See Confirmation. Reflexed for HIV ½ Differentiation and Confirmation Assay (HIV DIFF). Researchers estimate that, as of 2015, nearly 1.2 million people in the United States had HIV, but around 14 percent were unaware that they had the condition.

Human immunodeficiency virus is a slow replicating retrovirus that causes acquired immunodeficiency syndrome (AIDS). However, in patients with reactive initial combined HIV-1/-2 antigen and antibody test results, such negative results do not rule-out acute or early HIV-2 infection. If acute or early HIV-2 infection is suspected, detection of HIV-2 DNA/RNA (FHV2Q / HIV-2 DNA/RNA Qualitative Real-Time PCR) is recommended, based on the patient's clinical and epidemiologic exposure history. HIV-2's closest relative is SIVsm, a strain of SIV found in sooty mangabees. Since HIV-1 is derived from SIVcpz, and HIV-2 from SIVsm, the genetic sequence of HIV-2 is only partially homologous to HIV-1 and more closely resembles that of SIVsm. [citation needed] Diagnosis HIV-2 is a comparable T-lymphocytic retrovirus that is less virulent, but is becoming more widespread worldwide.

HIV 1+2 antigens are bond at the Test Zone (T) and antibodies are bond at the Control Zone (C). When the sample is added, it migrates by capillary diffusion rehydrating the gold conjugate. If present in sample, HIV 1/2 antibodies will bind with the gold conjugated antigens forming particles. The Multispot HIV-1/HIV-2 Rapid Test is a single use qualitative immunoassay to detect and to differentiate circulating antibodies to human immunodeficiency virus types 1 and 2 (HIV-1, HIV-2) in fresh or frozen human serum and plasma.
