The United Kingdom's Medicines and Healthcare products Regulatory Agency (MHRA) is urging the public to no buy unregulated HIV self-testing kits over the Internet, aidsmap.com reports.

According to the article, medical regulators are concerned that HIV self-tests that do not meet European safety and quality standards may provide unreliable results. Because the websites are registered outside the United Kingdom, they are not subject to federal regulations.

Free and confidential HIV tests are available in the country through publicly funded sexual health clinics, community outreach settings and some general practitioners.
