INTENDED USE:
The TRUSTwell HIV Ag-Ab ELISA Kit is a solid phase enzyme linked immunosorbent assay for the qualitative detection of HIV-1 P24 antigen, anti-HIV-1 including subtype O and anti-HIV-2 antibodies (including isotype IgG, IgM and IgA) in human serum or plasma. It is intended for professional use only as an aid in the early identification of infection with HIV-1 and HIV-2 viruses. Any reactive specimen with the TRUSTwell HIV Ag-Ab ELISA Kit must be confirmed with alternative testing method(s) and clinical findings.
TEST PRINCIPLE:
The TRUSTwell HIV Ag-Ab ELISA Kit is a solid phase enzyme linked immunosorbent assay based on the principle of the double antibody/antigen sandwich technique for the detection of HIV-1 P24 antigen and various antibodies against HIV-1 and/or HIV-2 antigen in human serum or plasma. The TRUSTwell HIV Ag-Ab ELISA Kit is composed by two systems: 1) Solid microwells pre-coated with Recombinant HIV-1 and HIV-2 antigens and anti-P24 antibody 2) Liquid conjugates composed of a. Recombinant HIV-1 and HIV-2 antigens conjugated with horse radish peroxidase (HRP-HIV 1+2 conjugates) and avidin conjugated with HRP (HRP-avidin conjugates) b. Anti-P24 antibody conjugated with biotin (Biotinylated P24 Ab)
During the assay, the test specimen is first incubated with the coated microwells and followed by incubation with biotinylated P24 Ab. The anti-HIV-1 and anti-HIV-2 antibodies, if present in the specimen, bind to the antigens coated on the microwell surface. If P24 present in the specimen, binds to the anti-P24 antibody on the microwell surface and biotinylated P24 Ab in the solution. In the next incubation with the HRP-HIV 1+2 and HRP-avidin conjugates, the above bounded anti-HIV-1 and anti-HIV-2 antibodies and bounded P24 antigen reactive to the HRP conjugates, forming HRP-complex. Unbounded conjugates are then removed by washing. The presence of the complexed conjugates is shown by a blue color upon additional incubation with TMB substrate. The reaction is stopped with Stop Solution and absorbance are read using a spectrophotometer at 450/620-690nm.
Clinical Performance:
A total of 1100 patient specimens from susceptible subjects were tested by the TRUSTwell HIV Ag-Ab ELISA Kit.
Relative Sensitivity: 100%,
Relative Specificity: 99.9%,
Overall Agreement: 99.9%.

TEST PRINCIPLE : TRUSTwell HIV 1+2 Ab ELISA Kit is a solid phase enzyme linked immunosorbent assay based on the principle of the double antigen-sandwich technique for the detection of the various antibodies against HIV-1 and/or HIV-2 in human serum or plasma. The TRUSTwell HIV 1+2 Ab ELISA Kit is composed of two key components: 1) Solid microwells pre-coated with recombinant HIV-1 and HIV-2 antigens; 2) Liquid conjugates composed of recombinant HIV-1 and HIV-2 antigens conjugated with horse radish peroxidase (HIV 1+2 HRP conjugates). During the assay, the test specimen is first incubated with the coated microwells. The anti-HIV-1 and anti-HIV-2 antibodies, if present in the specimen, bind to the antigens coated on the microwell surface. In the second incubation with the HRP- HIV 1+2 conjugates, the anti-HIV-1 and antiHIV-1 antibodies absorbed on the surface of microwell react to the HRP-HIV 1+2 conjugates. Unbounded conjugates are then removed by washing. The presence of the complexed conjugates is shown by a blue color upon additional incubation with TMB substrate. The reaction is stopped with Stop Solution and absorbance are read using a spectrophotometer at 450 /620-690 nm. Clinical Performance : A total of 1095 patient specimens from susceptible subjects were tested by the TRUSTwell HIV 1+2 Ab ELISA Kit.
