The HIV prevalence at the laboratory facilities ranged from 0.7 to two.8 , plus the two reference laboratories mentioned previously had the highest prevalence prices. Following adjusting for prevalence at each laboratory facility, pregnant women had been much less probably to have falsepositive screening test benefits than nonpregnant persons [adjusted OR 0.65, 95 self-assurance interval (CI) (0.six, 0.70)] (Table 2). Among all specimens with repeatedly reactive HIV EIA outcomes, these from pregnant girls have been much more likely to test Western blotnegative and indeterminate than these from persons who have been not pregnant (52.9 vs. 9.8 , p,0.0) and (7.0 vs. three.7 , p,0.0), respectively (Table 3). Amongst persons with indeterminate Western blot final results, the only band detected a lot more typically amongst pregnant females than amongst persons who were not pregnant was the p24 band (79 vs. 68 , p,0.0). The positive predictive value of your HIV EIA test among pregnant women was reduce than that amongst persons who had been not pregnant (30 vs. 86.5 , p,0.0) (Table three). Of 4,329 specimens with repeatedly reactive EIA and Western blotnegative results, 346 (eight.0 ) had a minimum of 1 followup testing occasion by July 2008: 0695 (.2 ) pregnant females, 9675 (7. ) nonpregnant persons, and 2703 (7. ) persons with unknown pregnancy status.

Of ,640 specimens with repeatedlyreactive HIV EIA and Western blotindeterminate benefits, 87 (.four ) had at least one followup testing event by July 2008: 70306 (22.9 ) pregnant women, 57633 (9.0 ) nonpregnant, and 6070 (eight.six ) unknown pregnancy status.
