Performance of rapid tests for HIV-1 antibody detection in paired serum and urine specimens of men who have sex with men / 中华微生物学和免疫学杂志

ABSTRACT

Objective:To compare the performance of rapid tests for HIV-1 antibody detection in serum and urine specimens of men who have sex with men (MSM) for investigating suitable technology in the prevention and control of AIDS in Beijing.Methods:A total of 874 cases of MSM were recruited in the AIDS clinic of Beijing Center for Disease Prevention and Control. HIV-1/2 antibody rapid test kit (Kit A, Alere Determine), urine HIV-1 antibody rapid test kit (Kit B, Wantai Biological Pharmacy) and HIV-1/2 antibody Western blot kit (Kit C, IMT) were used for antibody detection. The sensitivity, specificity and consistency of the three rapid test kits for HIV-1 antibody detection in serum and urine specimens were analyzed.Results:Among the 874 cases of MSM, 447 were positive for HIV-1 antibody (51.14%) and 427 were negative. One false negative result occurred by using Kit A and 23 by using Kit B. Taking Kit C as reference, the sensitivity of Kit A and Kit B was 99.78% and 94.85%, respectively; the specificity of both was 100%; the overall consistency was 99.89% ( Kappa=0.998) and 97.37% ( Kappa=0.947), respectively. Conclusions:Although the sensitivity of urine rapid test kit was not as sensitive as serum rapid test kit, it was more suitable for self-test due to its convenience in sampling, high safety and high accessibility. It was suggested that urine rapid test kit should be popularized in MSM population for HIV-1 antibody screening.
