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 PCR
The HIV RNA PCR test, also known as a viral load test, detects the actual genetic material (RNA) of the HIV virus in your blood. It is the earliest detection method available, capable of identifying HIV within 10 to 14 days after exposure.
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
The HIV RNA PCR test offers the earliest possible detection window, which is particularly valuable for individuals who suspect very recent exposure. Early detection during the acute phase of infection allows for prompt initiation of treatment and reduces the risk of onward transmission.
For individuals already on antiretroviral therapy, regular viral load monitoring confirms treatment effectiveness. Achieving and maintaining an undetectable viral load means the virus cannot be transmitted sexually, a principle known as U=U (Undetectable = Untransmittable).
When to Test
This test is particularly recommended when very early HIV detection is needed, such as within the first two weeks after a suspected exposure event. It is also the appropriate test for monitoring viral load in individuals who are receiving antiretroviral therapy.
Healthcare providers may also recommend this test for newborns of HIV-positive mothers, as antibody tests are unreliable in infants due to the presence of maternal antibodies.
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.
