MethodsAntiHIV1 antibody was tested in serum and urine samples from 59 HIVinfected persons diagnosed by Provincial Center for Disease Control and Prevention and 30 healthy controls with ELISA; Taking the results of the counterpart serum samples tested as standard, the sensitivity and specificity of antiHIV1 antibody in urine samples were calculated.ResultsAmong 59 HIVinfected cases, antiHIV1 antibody positive results of serum test were observed in all cases, while 53 urine samples showed positive and 6 ones were negative. None of the serum samples showed antiHIV1 antibody positive in the control group, but 1 urine sample was positive, which was determined to be negative by serum enzymelinked immunosorbent assay and electroselenium assay. The sensitivity and specificity for the urine ELISA were 89.83% and 96.67% respectively. ConclusionThe results indicate that urine antiHIV1 antibody can be tested to screen HIV infection in high risk population, if serum samples are unavailable.
