National testing algorithm.

The flow chart depicts Swaziland’s national testing algorithm for determination of HIV status. According to the national testing algorithm, a non-reactive first RDT is reported as HIV negative. In case of a reactive first RDT, a second RDT is conducted. If this second RDT is reactive, it is reported as HIV positive. However, if the result is non-reactive, a third RDT, Clearview COMPLETE HIV-1/2 (Chembio Diagnostic systems, Inc., Medford, NY, USA), is conducted. Non-reactive Clearview tests are reported as HIV negative while a reactive Clearview is reported as HIV inconclusive. Clients with inconclusive results are given another appointment to come after two weeks for a retest.
