Implication

Diagnostic validation study demonstrates rapid HIV-1 antibody detection in whole blood samples, suggesting great potential for simple qualitative screening in medical and veterinary care.

Key Points

To develop and validate a simplified, rapid whole-blood agglutination assay using autologous red blood cells to detect HIV-1 antibodies.
Conjugated a nonagglutinating monoclonal antibody specific for human red blood cells to a synthetic peptide antigen representing residues 579 to 601 of the HIV-1 envelope precursor.
Assayed 10 microliters of whole blood within a 2-minute reaction window and evaluated specificity via competitive inhibition with synthetic peptides.
Evaluated diagnostic accuracy in HIV-1 seronegative blood donors (n = 874) and confirmed HIV-1 antibody-positive samples (n = 81).
Detected HIV-1 antibodies in 10 µL of whole blood within 2 minutes, with agglutination selectively inhibited by free synthetic peptide but not unrelated peptides.
Demonstrated a false-positive rate of 0.1% among HIV-1 seronegative blood donors (n = 874).
Yielded a false-negative rate of approximately 1% among confirmed HIV-1 positive samples (n = 81).
