Read on for mo HIV-1/HIV-2/Syphilis Antibody Tests are available that allow simultaneous testing in the field at the point of care for both syphilis and HIV using the same blood Tests to detect antibody to HIV can be further classified as: 1) screening assays, which are designed to detect all infected individuals, or 2) confirmatory 483 products Anti-HIV-2 Antibody Products. Human Immunodeficiency Virus 2 (HIV-2) is an enveloped, spherical ssRNA retrovirus with a genome size of 9 kb. It is 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 Over 55% of the genetic material is different in these viruses.

HIV-2 is a comparable T-lymphocytic retrovirus that is less virulent, but is becoming more widespread worldwide. HIV-2 is more common outside of the United States, but cases have been reported in the U.S. HIV-2 antibody crossreacts with HIV-1 antigen, requiring a specific HIV-2 western blot to confirm antibody positives.

HIV antibody tests are highly sensitive, meaning they react preferentially with HIV antibodies, but not all positive or inconclusive HIV ELISA tests mean the person is infected by HIV. Risk history, and clinical judgement should be included in the assessment, and a confirmation test (western blot) should be administered.

This product is intended for use as an aid to detect antibodies against HIV (1+2) from individuals. HIV and AIDS are two distinct diseases that can affect humans of all ages. There's a lot of misinformation out there these viruses.

Indeterminate HIV-2 antibody results may be due to acute HIV-1 infection or very early HIV-2 infection (in individuals with risk factors). 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. 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 development of specific antibodies). 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).

This type is found worldwide. HIV-2. This type is mainly found in western Africa.

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, is less deadly and progresses more slowly. HIV-2 gp39 antibody-By direct ELISA (against recombinant gp39), 1:10,000 dilution will yield 0.3 O.D using alkaline phosphatase conjugated rabbit anti-mouse Ig. Introduction: Rapid HIV tests have been widely adopted globally as an important component of HIV prevention and control programs.
