HIV Ag & Ab Card (4th Generation)

Intended Use

HIV Ag & Ab Card (4th Generation) is a visual, rapid qualitative and sensitive solid phase immunochromatographic assay for the differential detection of HIV-1 p24 Antigen and Antibodies (IgM, IgG & IgA) to HIV-1& HIV-2 in Human Serum/ Plasma/ Whole blood (collected by venipuncture or Fingerprick). The test is a screening test for p24 antigen (HIV-1) and HIV antibodies (anti-HIV-1 & anti-HIV-2) and is for in vitro diagnostic use only. It is intended for screening of blood donors or other individuals at risk for HIV-1 & HIV-2 infection and for clinical diagnostic testing. It is a screening test for p24 antigen (HIV-1) and HIV antibodies (anti-HIV-1 & anti-HIV-2). The test is for in vitro diagnostic use only and is intended for screening of blood donors or others individuals at risk for HIV-1 and/or HIV-2 infection and for clinical diagnostic testing.

Principle

HIV Ag & Ab (4th Generation) Test kit consists two devices; one device for detection of HIV-1 p24 antigen and second device for the detection of HIV-1 & HIV-2 antibodies in human serum/ plasma/whole blood. HIV Antigen device contains two lines; “C” (Control Line) & “Ag” (HIV-1 p24 Antigen detection Test Line). Test line is coated with anti-p24 antibodies. When a sample is added to the HIV Antigen device followed by the addition of assay buffer, HIV-1 p24 antigen if present in the sample will bind to the anti-p24 gold colloid conjugate making antigen antibodies complex. This complex migrates along the membrane to the test region and forms the visible purple line at “Ag” region as antibody-antigen-antibody gold conjugate complex.

HIV Antibody test device contains two lines; “C” (Control line), & “Ab” (HIV-1 & HIV-2 Antibody detection Test Line). The test line is coated with HIV-1 & HIV-2 Antigens for the detection of HIV Antibodies. When a sample is added to the HIV Antibody device followed by the addition of assay buffer, anti-HIV-1 and/or anti-HIV-2 antibodies if present in the sample, bind to the respective HIV-1 and/or HIV-2 antigen gold colloid conjugate making antigen-antibodies complexes. These complexes migrate along the membrane to the test region and form the visible purple line at “Ab” region as antigen-antibody-antigen gold colloid conjugate complex.

The intensity of the test bands in the respective device will vary depending upon the amount of antigen/antibody present in the sample.

The appearance of any pink/purple color line in a specific test region should be considered as reactive for that particular antigen and/or antibody. A red procedural control line should always develop in the test device window to indicate that the test has been performed properly.
