RPR stands for which test used in infection-related dementia workups?

• A. rapid plasma reagin
• B. rapid plasma regain
• C. rapid protein reaction
• D. reactive plasma test

Answer: (A)

The test asked about is a non-treponemal screening test for syphilis used when evaluating potential infectious causes of dementia. It stands for rapid plasma reagin and detects reagin antibodies that react to a cardiolipin-containing antigen released during tissue damage from Treponema pallidum infection. This makes it a quick and inexpensive first-line screen in dementia workups because neurosyphilis can present with cognitive decline and is treatable if identified. Positive results are typically confirmed with a treponemal test, since non-treponemal tests can yield false positives or negatives in certain circumstances. The other options are not the standard name of this test.
