HIV Testing

We offer a number of different HIV tests at our clinic, including the HIV antibody and P24 antigen test, multiplex testing, early detection, and the instant HIV test.

Each of these tests has different window periods and is appropriate for different patients depending on how recently they’ve been exposed to the virus, or whether they are coming back for re-testing. For a standard HIV test, the testing window period is 6 weeks post-exposure. For HIV multiplex and RNA, 10 days post-exposure.

The test that can be taken soonest after exposure is the multiplex or RNA test, but if you are not sure which test is most appropriate for you, give us a call and our experienced team can help you decide on the best course of action.

Why Consider Specialised HIV Testing?

Specialised HIV tests offer more comprehensive and confidential testing. Our services cater to those seeking high-quality, precise HIV testing and care. Specialised HIV testing is crucial for early detection and management of HIV, a virus that can significantly impact the immune system. The focus of these services is on precision, privacy, and timely results, coupled with expert counseling and support.

How is HIV different from AIDS?
Not everyone who has HIV will develop AIDS. AIDS is the final stage in the development of an HIV infection, and with early detection and treatment, HIV can be managed so that AIDS does not develop. Current HIV medicines are much more effective now than they were even a few years ago, meaning that there are fewer cases of AIDS and better life expectancy for people with HIV.
The symptoms of HIV are very different depending on the individual and the stage of the infection. Some people will not experience any symptoms. Others will have nausea and vomiting, digestive issues, sudden weight loss, or chronic fatigue.
We recommend getting tested as early as possible after exposure, and retesting according to the relevant window periods. Some tests can be taken immediately, others will need to be taken at least 6 weeks after exposure.
