Rapid HIV Test
For in vitro diagnostic use only
Rapid HIV I&II Test Card is a single use, rapid test device,
double antigen sandwich immunoassay for qualitative detection of
antibodies to Human Immunodeficiency Viruses or HIV I&II in
serum, plasma or whole blood. It is intended for medical
institution as the aid for the diagnosis of possible HIV infection.
The product may be used for the quick screening of blood donors and
Rapid HIV I&II Test Card employs chromatographic lateral flow
device in a cassette format. Colloidal gold conjugated recombinant
antigens(Au-Ag) corresponding to HIV-1 gp 120, gp41 and HIV-2 gp-36
are dry-immobilized at the end of nitrocellulose membrane strip.
HIV 1+2 antigens are bond at the Test Zone (T) and rabbit anti-HIV
1+2 antibodies are bond at the Control Zone (C). When the sample is
added, it migrates by capillary diffusion rehydrating the gold
conjugate. If there are HIV1 or HIV2 antibodies in sample, they
will bind with the gold conjugated antigens forming particles.
These particles will continue to migrate along the strip until the
Test Zone (T) where they are captured by the HIV 1+2 antigens
generating a visible red line. If there are no HIV1 or HIV2
antibodies in sample, no red line is formed in the Test Zone
(T).The gold conjugate will continue to migrate alone until it is
captured in the Control Zone (C) by the rabbit anti-HIV1+2
antibodies aggregating in a red line, which indicates the validity
of the test.
