The traditional algorithm for serological syphilis testing starts with a non-treponemal assay such as the VDRL (venereal disease research laboratory) or RPR (rapid plasma reagin) tests to screen patients, with reactive samples followed up by a Treponema-specific method.

In February 2011, the CDC reiterated their long-standing preference for this testing sequence, but also made recommendations for facilities that want to implement an immunoassay-first "reverse" algorithm. Find out how this shift in syphilis-screening SOP could affect your lab.

The American Association for Clinical Chemistry (AACC) is hosting a Webinar on September 14 from 2 to 3 pm (EST) that will present:

  • Characteristics of the various serological syphilis tests and test algorithms
  • Implications of using Treponema-specific immunoassay for initial screening
  • How one big lab validated testing for their move to the "reverse" algorithm
  • Guidelines for interpretation of syphilis serologic testing
  • Rationale for recent CDC recommendations, straight from a CDC leader!

The experts will be:

  • Gail Bolan, MD, director, Division of STD Prevention, Centers for Disease Control and Prevention, Atlanta
  • Jennifer Shieh, MS, CLS, test development scientist, Kaiser Permanente TPMG Regional Laboratory, Berkeley, Cali
