What is an HIV PCR Test?
The HIV PCR test (Polymerase Chain Reaction) directly detects the genetic material (RNA) of HIV in a blood sample. This test directly identifies the virus itself, rather than waiting for the body to produce antibodies, making it highly sensitive for the early detection of HIV infection. It is beneficial for diagnosing HIV in newborns and in cases where early infection is suspected.
Main reasons or symptoms for doing the HIV PCR Test
-
Early detection of HIV infection soon after exposure
-
Diagnosis of HIV in infants born to HIV-positive mothers
-
Confirming HIV status when other tests give inconclusive results
-
Monitoring HIV viral load in people living with HIV to assess treatment response
-
Testing during the window period when antibody tests may be negative
How to prepare for an HIV PCR Test
No special preparation or fasting is required. A blood sample will be collected, typically from a vein in the arm for adults or via heel/toe prick for infants.
Please inform us if you require pre-test counseling before the test.
Typical Reference Values – Normal result ranges
-
Negative: No HIV genetic material detected (no infection)
-
Positive: HIV RNA detected (infection present)
Detection Window Period for HIV PCR Test
The HIV PCR test can detect HIV as early as 7 to 10 days after exposure, significantly earlier than antibody or antigen/antibody tests. This is because it identifies the virus itself during the initial phase of infection when the viral load is very high. The window period for reliable detection is generally between about 7 days and 4 weeks post-exposure. This makes the PCR test the preferred choice for early diagnosis, especially within the first month after potential exposure.
