Fourth-generation HIV assays detect both HIV-1/2 antibodies and HIV-1 p24 antigen, enabling earlier diagnosis compared to antibody-only tests. Cnpair offers a comprehensive range of raw materials for HIV antibody and antigen detection, covering HIV-1 (Group M & O) antigen, HIV-2 antigen, and HIV-1 p24 antibodies, which fully meet the requirements of fourth-generation HIV immunoassays. Our raw materials facilitate earlier diagnosis and help minimize the risk of missed infections.
Cnpair HIV Ag ＆ Ab Performance
1 Outstanding Sensitivity & Specificity
Demonstrated excellent performance on CLIA, validated with 1,762 clinical samples, achieving 99.93% negative concordance (N=1,465) and 100% positive concordance (N=297).
2 Ultra-Low Detection Limits
Antibody Detection: LOD = 0.2 NCU/mL (HIV -1)
Antigen Detection: LOD = 2.5 U/mL
3 Excellent Stability
Maintains consistent performance after 12 days at 37°C, with positive signal variation within ±30%, ensuring robust reagent stability.
4 Verified with National Reference Panels
Validated with the Chinese National Reference Panel for HIV Antibodies (HIV Ag/Ab Chemiluminescence Immunoassay), Cnpair’s HIV antigen and antibody raw materials achieved 100% concordance, including HIV-1 Group O samples.
