Abstract


Background: HIV is one of the major public health issues of modern world. The elevation in numbers calls for increased and efficient diagnostic testing protocols. A great number of HIV diagnostic tests have been approved and in use in the developed world but developing countries are still lagging in terms of testing HIV. These reasons are the motives behind this study which is aimed at testing the accuracy and use of Calypte HIV-1 Urine EIA in the Pakistani population.

Methods: 516 subjects are included in the study from different HIV centers of Pakistan. The test results of Calypte-HIV-1 Urine EIA were compared with the routinely used 3-kit method.

Results: The results exhibited 100% specificity but low sensitivity (74.67%). However, the positive predictive value and negative predictive value were 100% and 52.94%, respectively. Overall accuracy result for this kit was observed to be 81.40% for Calypte HIV-1 Urine EIA in the selected sample.

Conclusion: Pakistan has a low population prevalence of HIV and keeping in view of the WHO recommended guidelines for HIV testing, the use of Calypte HIV-1 Urine EIA is not ideal in the current scenario. Even though the test can be of great value in high prevalence populations and can be an excellent means of surveillance procedures, it is not as fit to be used in diagnostic settings in the current situation in developing countries.
