What this test is

The rapid plasma reagin test is a screening tool that detects antibodies released during syphilis infection. It is often used alongside other tests to help confirm a diagnosis. Because it can sometimes react to conditions other than syphilis, results are interpreted with your health history.

What it measures

  • Reagin antibodies — Antibodies that may be produced during syphilis infection or other conditions
  • RPR titer — A number that indicates the amount of reagin antibodies present, if reactive
  • Reactive or non-reactive result — A qualitative interpretation of whether antibodies were detected

What the test involves

A healthcare professional collects a small sample of blood from a vein in your arm using a standard blood draw. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order an RPR test if you have symptoms that could suggest syphilis or if you have been exposed to the infection. It is also used as a routine screening test for people at higher risk or during pregnancy.

Preparation

In most cases, no special preparation is needed before an RPR test. However, always follow the specific instructions provided by the collection lab or your clinician.

How results are reported

Results are typically reported as reactive or non-reactive, sometimes with a titer value that shows the level of antibodies. Reference ranges and reporting methods can vary between laboratories, so your clinician will interpret the results in the context of your health.

Before you go

  • Whether any special preparation is needed before your blood draw
  • How and when you will receive your test results
  • Whether additional tests might be ordered based on your results
