Doctor's Assessment Included
Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
HIV RNA test (PCR): direct detection of the virus
An HIV RNA test uses PCR to detect the genetic material (RNA) of the virus directly, which allows some of the earliest possible detection. It is a more specialized, higher-cost test often considered after a recent possible exposure. A result would always be interpreted by a doctor, and any reactive finding needs confirmatory testing.
What It Measures
This test directly measures the amount of HIV RNA present in your blood, expressed as the number of viral copies per millilitre. It uses PCR technology to amplify and detect viral genetic material, even when present in very small quantities.
Beyond initial diagnosis, this test is also used to monitor the effectiveness of antiretroviral therapy by tracking changes in viral load over time. An undetectable viral load is the goal of successful HIV treatment.
Why It Matters
Because it looks for the virus itself rather than the body response to it, an RNA test may pick up a possible infection earlier than antibody-based tests. This can be relevant when clarity soon after a possible exposure feels important. Any outcome is best discussed with a doctor, who can advise on confirmatory steps.
When to Test
An HIV RNA test can detect infection from roughly 10 to 14 days after a possible exposure, which is earlier than most antibody tests. Even so, a single early result may not be conclusive on its own. It can be helpful to discuss the timing and whether a later antibody test is also wise with a doctor or the GGD.
Recommendations
Male
Not detected result indicates no HIV RNA found. Continue safe practices and regular testing if at risk.
Detected result indicates active HIV infection. Seek immediate consultation with an infectious disease specialist for treatment initiation.
Female
Not detected result indicates no HIV RNA found. Continue safe practices and regular testing if at risk.
Detected result indicates active HIV infection. Seek immediate consultation with an infectious disease specialist for treatment initiation.
Lifestyle Tips
If you are at ongoing risk of HIV exposure, discuss regular testing schedules and pre-exposure prophylaxis (PrEP) with your healthcare provider. Consistent condom use remains one of the most effective prevention methods.
If you are living with HIV, adhering to your antiretroviral therapy as prescribed is essential for maintaining an undetectable viral load. Attend all scheduled medical appointments and communicate openly with your healthcare team about any challenges with medication adherence.
