Misclassification of HIV infection status among serologically diverse populations in Nigeria: implications for test and treat program

We identified no instances of misclassification of positive HIV status suggesting that all clients who have been placed on treatment truly had HIV infection. The 100% concordance rate recorded from all the sites may be attributable to the maturity of the HIV program in Nigerian with a concomitant standard quality assurance system for both clinical and outreach testing services. This finding supports the implementation of the Test and Treat policy that Nigeria has adopted. Scale up of Test and Treat and community ART is thus recommended to increase access to treatment.
