Overview
HIV RNA testing detects viral RNA and can identify infection earlier than antibody tests in some situations. It may also be used for confirmation or viral load monitoring.
What it detects
HIV viral RNA.
Sample type
Blood sample.
When it may be appropriate
Very recent exposure, confirmatory testing, suspected acute infection or monitoring.
Window period considerations
May detect infection earlier than antibody-based tests, but timing still matters.
Test limitations
Cost and availability vary; not always used for routine screening.
Interpretation basics
Detectable RNA suggests HIV infection but must be interpreted with clinical context.
Follow-up recommendations
Positive results require confirmatory and care linkage; negative results may need repeat testing after exposure.
Key points
- Detects viral RNA
- Can be earlier than antibody tests
- Useful in selected cases
- Requires clinical interpretation
When to seek care
- Very recent exposure
- Suspected acute HIV
- Confirmatory testing
