Human Immunodeficiency Virus Resistance Testing Technologies and Their Applicability in Resource-Limited Settings of Africa

There has been tremendous breakthrough in the development of technologies and protocols for counselling, testing, and surveillance of resistant human immunodeficiency virus strains for efficient prognosis and clinical management aimed at improving the quality of life of infected persons. However, we have not arrived at a point where services rendered using these technologies can be made affordable and accessible to resource-limited settings. There are several technologies for monitoring antiretroviral resistance, each with unique merits and demerits. In this study, we review the strengths and limitations of prospective and affordable technologies with emphasis on those that could be used in resource-limited settings.
