Rapid Plasma Reagin Screen Response to Therapy, Serum

Rapid Plasma Reagin Test (RPR); Syphilis G; Syphilis Serology (RPR); Treponema pallidum (T. pallidum); Automated Reagin Test (ART)

Useful for:

• Determining the current disease status and evaluating response to therapy for syphilis


• This test should not be used as a primary diagnostic approach for syphilis
  
  
  
  • To screen patients for an undiagnosed syphilis infection, order SYPHT (Syphilis Total Antibody with Reflex, Serum)
  
  
  
  


• This test is not useful for testing spinal fluid specimens


• This test is not intended for medical-legal use


• This assay provides a rapid plasma reagin (RPR) screen and can be used to monitor response to therapy in patients treated for syphilis infection


• If this test is positive, then the titer will be performed at an additional charge

Biological false-positive reactions with cardiolipin-type antigens have been reported in disease such as infectious mononucleosis, leprosy, malaria, lupus erythematosus, vaccinia, and viral pneumonia. Pregnancy, autoimmune diseases, and narcotic addictions may give false-positive results. Pinta, yaws, bejel, and other treponemal diseases may also produce false-positive results with this test
