Human immunodeficiency virus type 2 (HIV-2) is a lentivirus, a retrovirus in the same genus (Lentiviridae) as HIV-1. It was first isolated in 1986 in West Africa, where it is currently endemic. 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 difference between HIV-1 and HIV-2 are as follows. HIV-1 is the most common type of HIV and accounts for 95% of all infections, whereas HIV-2 is relatively uncommon and less infectious. HIV-2 is mainly concentrated in West Africa and the surrounding countries. HIV-2 is less fatal and progresses more slowly than HIV-1. Currently, only one antibody test can distinguish between antibodies to HIV-1 or HIV-2. 2. HIV-1/HIV-2 antibody differentiation immunoassay 1.

Hiv 1 2 antibody

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. The HIV antibody test advised by the CDC is the HIV-1/2 antigen/antibody combination immunoassay test. If you test positive for HIV, the CDC advises the following follow-up tests: HIV-1/HIV-2 antibody differentiation immunoassay. This test is to confirm HIV and find out if you have HIV-1 or HIV-2.

Microwell strip plates (the solid phase) are coated with purified antigens; gp160 and p24 recombinant proteins derived from HIV-1; a peptide representing the immunodominant region of the HIV-2 transmembrane glycoprotein, gp36; and a synthetic polypeptide mimicking as HIV-1 RNA Positive HIV-1/2 Antibody Negative Plasma.

2012-08-08 · Zambia’s HIV prevalence of 13.5% makes HIV testing a national health priority and the national HIV testing algorithm specifies sequential blood-based rapid antibody tests: first Determine®HIV-1/2 Antibody (Inverness Medical) is used, which if reactive is followed by a different antibody test, Uni-Gold TM Recombigen HIV-1/2 Antibody (Trinity Biotech).

HIV-2 Positive Positive for HIV-2 antibodies. Laboratory evidence of HIV-2 infection is present. Provider case reporting required* D 1. HIV-1/2 Ag/Ab combo immunoassay 2. HIV-1/HIV-2 antibody differentiation immunoassay 3. HIV-1 RNA assay 1. Reactive 2.

HIV-1/HIV-2 antibody differentiation immunoassay 3. HIV-1 RNA assay 1. Reactive 2. Nonreactive or Indeterminate 3. Not detected HIV antibodies were not confirmed and HIV-1 RNA was not detected. Repeatedly reactive results on fourth-generation screening tests require confirmation with a supplemental test, such as an HIV-1/HIV-2 antibody differentiation assay. Differentiation between HIV-1 and HIV-2 antibodies can have treatment implications, as HIV-2 does not respond to some antiretroviral agents.

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: Se hela listan på avert.org HIV Testing anytime, anywhere, made easy.

About 1 in 5 people who are infected with HIV don't know it because they may not have symptoms.

If the HIV-1/HIV-2 antigen/antibody test is positive, an antibody-based HIV-1/HIV-2 test is done (at additional charge) to confirm infection and identify whether it is caused by HIV-1 or HIV-2. However, the HIV-1/HIV-2 differentiation test will be negative during acute infection (prior to …
