Abstract
It is a common practice in resource-constrained countries to accept two positive rapid HIV antibody test results as diagnostic for HIV infection. Because these tests are inexpensive and results are obtained quickly, they are recommended by the WHO to "scale-up" HIV testing to increase the number of people tested. The negative predictive value of rapid HIV tests is so high that negative results are considered conclusive despite the fact that false-negative results can occur in several situations. While the specificity and sensitivity of rapid HIV tests in resource-rich countries is acceptable, there are only limited data about their performance in resource-constrained countries. The challenges of rapid HIV testing in these situations will be discussed.
