Early Detection Transforms Outcomes
HIV treatment has transformed what was once a fatal diagnosis into a manageable chronic condition. With modern antiretroviral therapy, people with HIV can live long, healthy lives and cannot pass on the virus to partners. Testing is the essential first step.
Human Immunodeficiency Virus (HIV) attacks the immune system's CD4 cells. Without treatment, HIV progresses to AIDS (Acquired Immunodeficiency Syndrome). However, early diagnosis and antiretroviral therapy (ART) means people with HIV now have near-normal life expectancy. Crucially, effective treatment makes HIV untransmissible - Undetectable = Untransmittable (U=U). Testing removes uncertainty and opens the door to excellent care.
HIV testing involves either a rapid finger-prick test (results in 20 minutes) or laboratory blood test. Fourth-generation tests detect both HIV antibodies and p24 antigen, enabling earlier detection from 4 weeks post-exposure. We offer confidential testing with full support regardless of result. A reactive result requires confirmatory testing before diagnosis.
Antiretroviral therapy (ART) involves taking daily medication that suppresses HIV to undetectable levels. Treatment is lifelong but highly effective and generally well-tolerated. Starting treatment early preserves immune function and prevents complications. Undetectable viral load means you cannot transmit HIV sexually (U=U). Regular monitoring ensures treatment effectiveness.
Fourth-generation tests (which we use) can detect HIV from 4 weeks (28 days) after exposure with high accuracy. For complete certainty, we recommend testing at 6 weeks and confirming at 12 weeks. If you're experiencing symptoms of acute HIV infection, test immediately as viral load tests may detect infection earlier.
U=U means that people living with HIV who take their medication and have an undetectable viral load (below 200 copies/ml) cannot transmit HIV to sexual partners. This is supported by major studies and endorsed by medical organisations worldwide. It's a game-changer for people living with HIV.
Condoms remain highly effective. Regular testing enables early diagnosis and treatment if needed. PrEP (Pre-Exposure Prophylaxis) is available through NHS sexual health clinics for those at higher risk. Discuss your risk factors with a healthcare provider for personalised advice.
