Free and confidential HIV testing can be accessed during NAZ's office hours: Monday to Friday between 9:30am and 5:30pm. Please call us at 020 8741 1879 to schedule an appointment. Walk-ins are accepted and a test will be delivered, assuming a staff member or volunteer is available. Appointments usually last 30 minutes. NAZ uses a rapid finger prick that tests for HIV within 5 minutes. Also, we provide pre- and post- counselling and a variety of other sexual health information and resources as part of the test. Clients will need to fill out a confidential form detailing their health and sexual health history in our offices prior to the test. We also provide HIV testing at various outreach sites.
