This test utilises
synthetic and recombinant antigens representing envelope and
gag glycoproteins of HIV 1 and 2, immobilised on a membrane,
enclosed in a specially designed test-device. 2 ml of the saliva
sample is measured, using the pipette provided with the kit. The
sample is filtered through the filter funnel and flows through
the membrane as antibodies in the sample, if present, react with
the antigens immobilised onto the membrane. Next, a reagent
consisting of a specific binding partner conjugated to colloidal
gold (Reagent B) is applied which binds to human antibodies (IgG)
that are attached to the antigens on the membrane. Within a few
minutes, the results appear on the membrane. Excess conjugate
is removed by applying additional Reagent A (buffer solution).
Appearance of a control dot shows that the test is functioning as
designed. Two pink dots approximately 2 mm in diameter indicate
an HIV reactive or positive specimen.
