This is a plain English summary of an original research article. The views expressed are those of the author(s) and reviewer(s) at the time of publication.

Kits for HIV self-testing are an effective and acceptable way of increasing HIV testing among trans people. Existing HIV testing services are often designed around men who have sex with men. This can create barriers for trans men and trans women, who are at high risk of HIV.  Many go undiagnosed as a result.

A review of previous evidence showed that HIV self-testing could increase diagnoses among men who have sex with men and trans people. However, the research included few trans people. The team therefore recruited 118 trans people into a trial of HIV self-testing. They found that HIV self-testing was acceptable to them, and increased the take up of HIV testing, compared to providing information about local sexual health services. 

The researchers interviewed some of the participants about sexual health services.  Many had previously encountered a lack of understanding of the trans experience, been referred to by the wrong pronoun, or found that resources were not appropriate for their anatomy. These negative experiences discouraged them from seeking HIV testing through the usual sexual health services, and may explain why self-testing was more popular. 

The researchers say their study shows the need both for wider provision of self-testing, and better services for trans people.

What’s the issue?

Trans is a general term for people whose gender is different from the gender assigned to them at birth. There is no official figure of how many people in the UK identify as trans, but the current estimate is of between 20,000 and 50,000 people. They are at higher risk of HIV than others, for multiple reasons including social inequality, and barriers to prevention services.

In HIV self-testing, people give themselves a finger prick blood test, process the sample and read their own result. The researchers pooled evidence on self-testing for HIV from 10 studies including 5,486 men who have sex with men and 4,121 female sex workers. Only two of the studies (one from China, one from the US) included trans people (69 trans women and 3 gender queer or neutral). In these two studies, self-testing increased the numbers of trans people having HIV tests.

The researchers wanted to know whether self-testing for HIV would be acceptable to trans people in the UK, and whether it would increase the numbers getting tested. They also wanted to know what barriers this group faces in getting tested for HIV through existing sexual health services.

What’s new?

The researchers recruited 94 trans men and 24 trans women to the study. They were randomly assigned to receive through the post either a HIV self-test kit, or information about their nearest testing centre. They completed a survey after 3 months.

They found that:

    • one in three participants had not been tested for HIV before the study 
    • people who were sent the self-test kit were three times as likely to get tested for HIV, compared to those sent information only - almost all of those sent the kit (43 of 46) had taken a test after three months, compared to fewer (6 of 22) who were offered information 
    • almost all (38 of 39) found the instructions easy to understand, the test simple to use (37 of 38), and all reported a good overall experience.

A smaller group of 20, who used the kit in the first part of the study, were then randomly assigned either to have no further contact, or to receive regular reminders and further self-test kits. Those offered these repeat tests were again three times more likely to test during the following two years, compared to those sent only the first test (though these numbers were small).

None of the participants of the trial tested positive for HIV, probably because of the small numbers included. That means the study cannot say whether or not self-tests lead to earlier diagnoses for trans people who have HIV. But importantly, the researchers did not identify any harms from self-testing, such as people being less likely to be tested for other sexually transmitted diseases. 

Researchers then interviewed 20 people within the study about their previous experience of HIV testing. They wanted to explore unmet needs that might be addressed by self-testing.  Some reported good experiences, and services designed for trans people were highly valued. 

Others had experienced problems such as: 

    • a lack of cultural understanding, skills and empathy of clinic staff, who treated trans people as a burden, addressed them with the wrong pronoun or called their sexual orientation and HIV risk into question
    • clinic pathways designed for men who have sex with men led to offers of examinations or procedures inappropriate for trans people’s anatomy, or recording systems that did not accommodate trans identity 
    • worries that discussing their bodies in HIV clinics would trigger unease about gender identity, especially for those in the early stages of transition.

Why is this important?

The research underlines the need to reach more trans people with HIV testing options that are suitable for them. Self-testing was highly acceptable and could dramatically increase HIV testing in this group without reducing testing for other sexually transmitted infections (STIs). 

However, HIV self-testing is not the only option. People need sufficient social support, and care services in the event of a positive test. They should be able to access clinic facilities for HIV testing that are appropriate, regardless of their gender identity. 

The evidence from interviews demonstrates that some existing HIV testing services are failing to meet the needs of trans people. Solutions such as staff training, or designing services with input from trans people, could help to redress the balance. 

What’s next?

The research team is writing up the results of the wider study, which also included 10,017 men who have sex with men. 

However, they say the results published so far show that HIV self-testing is effective, increases HIV testing among men who have sex with men and trans people, and should be implemented.

Further monitoring is needed to ensure that people who test positive can access health services, the researchers say. Nobody in this study tested positive so access was not explored. The researchers say more work is also needed on HIV testing among trans women and non-binary people.
