HIV Self-Testing: Can South African Men Handle It?
"New research explores whether oral fluid and fingerstick HIV self-tests are usable by South African men, a key population in the fight against HIV."
In South Africa, where the HIV-positive population is among the highest in the world, traditional HIV testing methods often fall short, particularly for men. Men test at significantly lower rates than women, creating a critical gap in efforts to curb the spread of the virus. This disparity is further exacerbated among men who have sex with men (MSM), a high-risk group often facing additional barriers to accessing healthcare.
HIV self-testing (HIVST) emerges as a promising alternative, potentially increasing testing uptake and facilitating earlier diagnosis and treatment. But how usable are these tests for the populations who need them most? A recent study in South Africa dives into this question, examining the ability of MSM to correctly use oral fluid and fingerstick HIV self-tests.
This article explores the findings of this research, revealing the challenges and successes of HIV self-testing among South African MSM and highlighting the crucial role of accessible instructions and targeted support.
Measuring HIV Self-Testing
HIV self-testing (HIVST) is presented as a way to address healthcare needs among high-risk populations, particularly men who have sex with men (MSM). A 2024 systematic review and meta-analysis assessed HIVST prevalence among MSM during the preceding five years. In the United States, CDC data systems include the National HIV Behavioral Surveillance (NHBS), which collects information on HIV testing behaviors, behavioral risk factors, prevention services, and prevention strategies. NHBS participants are also offered an HIV test regardless of their self-reported HIV status.
Lowering Barriers to Testing
A systematic review examined HIV testing among Internet-using MSM in the United States, including whether participants had ever tested, had tested within the previous 12 months, or had tested repeatedly during that period. Its findings identified unmet testing needs among some Internet-using MSM and suggested targeted outreach, including the provision of HIV self-testing kits. The broader history of HIV testing has included anonymous test sites and rapid HIV testing in general-practitioner clinics as efforts to reduce fear, stigma, and other barriers. HIV.gov's timeline places these developments within the United States HIV and AIDS history, beginning with the first reported cases in 1981.
Decoding HIV Self-Testing Usability: What the Research Reveals
The study, conducted in Mpumalanga, South Africa, involved MSM with varying degrees of experience with HIV self-testing. Researchers assessed the usability of both oral fluid (OF) and fingerstick (FS) HIVST kits across three phases: Phase I: HIVST-naïve MSM received a brief demonstration before conducting observed self-tests.
Evidence from South Africa
Research from Mpumalanga Province reports that clinic-based testing can be impractical for MSM who face barriers and stigma related to public health services because of their sexual orientation. A review of HIV self-testing in Southern Africa describes a longitudinal South African study among MSM as showing extremely high uptake and acceptability after HIVST kits were distributed. Instructional support may also matter: one cited study found that adults given a finger-stick HIV test instructional video committed fewer errors, even when they had previously received in-person demonstrations. A 2024 modeling analysis examined how increased HIVST could relate to future HIV incidence and awareness of HIV status among MSM.
Accuracy and User Error
Evidence summarized for South African MSM indicates that oral-fluid and finger-stick HIV self-testing can be used by participants, but performance is not free from limitations. Studies conducted in Africa reported sensitivity of self-conducted oral-fluid testing at 90% or higher and specificity consistently at or above 95%. One South African study among healthcare workers found lower sensitivity, primarily attributed to poor reading of weak positive results and insufficient instructions. Research using counselor-observers also has a potential limitation, because being watched may cause participant discomfort and influence how testing is performed.
Self-Testing Versus Standard Services
A randomized trial compared home-based oral-fluid rapid HIV self-testing with mail-based blood-sample collection and medical or community testing among young adult Black, Hispanic, and White MSM. The trial found no differences in assigned test completion by race or ethnicity. Although free home-based oral-fluid testing showed moderate promise, it did not produce greater testing than directing participants to medical or community testing venues. A 2022 systematic review and meta-analysis reached a more favorable overall conclusion, reporting that oral HIVST could increase testing and detection of new infections among MSM who might not otherwise test, while noting that more research from low- and middle-income countries is needed for generalizability.
The Future of HIV Self-Testing: Accessible Instructions are Key
The study underscores the importance of accessible and user-friendly instructions, especially for fingerstick HIV self-tests. While the oral fluid tests proved relatively easy to use, the fingerstick tests required more careful attention to detail and technique.
Knowledge and Prior Use
The cited 2024 evidence synthesis examined knowledge and prior use of HIV self-testing among MSM. Participants were recruited from a sexual health clinic and two community-based testing sites. This design places HIVST experience within both clinical and community testing settings. The source reports the study's focus on knowledge and previous use rather than presenting a universal measure for all South African men or all MSM.
Market Growth and Decentralized Testing
Future Market Insights valued the HIV self-testing market at USD 240.1 million in 2025. Its forecast estimates growth to USD 272.8 million in 2026 and USD 971.8 million by 2036, with a projected compound annual growth rate of 13.6%. Other cited market outlooks describe growing interest in privacy, convenience, early detection, and accessible testing options. A separate industry outlook identifies decentralized testing as a future direction in which self-tests become more integrated into national HIV prevention and control programs.
From Access to Care
HIV self-testing is not only a way to obtain a result; testing is also the first step toward tailored prevention strategies and treatment-based HIV prevention. The Lancet source emphasizes the importance of creating a strong social norm for testing in communities at risk, particularly among MSM who may test repeatedly. Future innovations described by Nature Index include improving sensitivity and specificity, streamlining digital guidance, and embedding self-testing within broader prevention and care cascades. A 2025 review characterizes digital health as a way to interface with individuals and communities to monitor and address health needs while supporting private, convenient, and accessible HIV testing.
The research also highlights the potential of increased experience and exposure to HIVST to improve usability. As participants became more familiar with the process, they made fewer errors and reported greater ease and confidence in their ability to conduct the tests.
HIV self-testing holds significant promise for increasing HIV testing rates and promoting earlier diagnosis and treatment among key populations like MSM in South Africa. By addressing the challenges in usability and ensuring access to clear and effective instructions, we can unlock the full potential of this innovative approach to HIV prevention.
