What should be done for persons who have an HIV diagnosis and an RTRI result with only the control line (i.e., RTRI inconclusive or negative)?

Although this may happen, it should be rare. In countries where regulation or policy permits, programs may consider repeating the national algorithm to confirm HIV-positive status (if retesting for verification was not done). In general, RTRI should be repeated and the results recorded. Irrespective of RTRI results, the national HIV testing algorithm is always the final HIV result. It is important to review inconclusive results in the context of total number of HIV-positives tested. From the review of >60,000 HIV-positive samples tested by Asante in multiple countries, almost 99.8% were classified either as long-term or recent with only 0.2% with inconclusive results.
