A leading blood test laboratory of India, Dr Lal PathLabs now makes it easy and convenient for patients to check their lab test results online with just a couple of clicks.

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-1 Antibody by Multispot Human Immunodeficiency Virus 1/2 (HIV-1/2) Antibody, Differentiation With Reflex to HIV-1 RNA Human Immunodeficiency Virus Types 1 and 2 (HIV-1/2) Antibody Differentiation, Supplemental, with Reflex to HIV-1 Quantitative NAAT, Plasma Reactive HIV-1 antibody but positive HIV-2 antibody results usually indicate the presence of HIV-2 infection with HIV-1 antibody cross-reactivity (eg, presence of only HIV-1 gp41 and/or gp160 band). However, such results may be rarely due to HIV-1 and HIV-2 coinfection. Human immunodeficiency virus type 2 (HIV-2) is a lentivirus, a retrovirus in the same genus (Lentiviridae) as HIV-1.

As of June 2010, CDC has reported a total of 166 cases that met the CDC case definition of HIV-2 infection in the United States. 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.

Reactive HIV-1 antibody but positive HIV-2 antibody results usually indicate the presence of HIV-2 infection with HIV-1 antibody cross-reactivity (eg, presence of only HIV-1 gp41 and/or gp160 band). However, such results may be rarely due to HIV-1 and HIV-2 coinfection.

All reactive HIV-1/2 antigen-antibody tests require confirmatory testing. None of the HIV-1/2 immunoassays can detect HIV-2 core antigen (p26 antigen), but cross-reactivity to HIV-1 p24 antigen can occur in persons infected with HIV-2. Six laboratory-based HIV-1/2 antigen-antibody immunoassays are FDA-approved for use in the United States:

This type is found worldwide. HIV-2. This type is mainly found in western Africa. HIV 1/2 antibody test kit (colloidal gold) is intended for qualitative detection of HIV 1/2 antibody in human serum or plasma, applying to auxiliary diagnosis of HIV infection. Assay is a chemiluminescent immunoassay for the qualitative detection of antibodies to HIV-1 Groups M and O and/or antibodies to HIV-2 in human serum and plasma.
