Overview
The RPR test is a nontreponemal blood test for syphilis. Like VDRL, it can be used for screening and monitoring treatment response.
What it detects
Nontreponemal antibodies associated with syphilis.
Sample type
Blood sample.
When it may be appropriate
Syphilis screening, diagnosis support and follow-up.
Window period considerations
May take several weeks after infection to become positive.
Test limitations
False positives can occur; results must be interpreted with treponemal tests.
Interpretation basics
Reactive results need confirmation; titers help monitor response.
Follow-up recommendations
Confirm with treponemal test and plan stage-appropriate care.
Key points
- Similar role to VDRL
- Screening and titer monitoring
- Needs confirmation
- Timing affects sensitivity
When to seek care
- Syphilis screening
- Treatment follow-up
- Partner evaluation
