 In the 2018 Nigerian AIDS Indicator and Impact Survey, an AIIS, a cross-sectional household survey, it was found that 5.1% of individuals tested positive for HIV-1 antibodies on the first test, test 1, but only 1.44% of these individuals were confirmed to be HIV-positive after serial testing with test 2 and the tie-breaking test 3. The national algorithm had a false positive rate of 5.5%, indicating that the algorithm may need to be evaluated further in order to ensure accurate HIV diagnoses in routine HIV testing services.
