Certified Practice: DST Update Notification (STI)

Posted Nov. 19, 2015

The BC Public Health Microbiology Reference Lab (BC PHMRL) has recently implemented new tests, including Nucleic Acid Test for Trichomonas vaginalis and Enzyme Immune Assay (EIA) for syphilis. Both are DNA tests that are more sensitive and specific for the identified infections. The changes are supported by the BC PHMRL and BCCDC’s STI clinical leadership team.

As a result of this change, two STI DSTs have been revised.

The STI Assessment DST has been revised as follows:

  • T. vaginalis (trichomonas) nucleic acid test (NAT) has been added
  • testing for syphilis screening has changed to Enzyme Immune Assay (EIA) and replaces rapid plasma reagin (RPR)
  • Syphilis polymerase chain reaction (PCR) lesion swab has been added

The Trichomoniasis DST has been revised as follows:

  • T. vaginalis (trichomonas) nucleic acid test (NAT) has been added and replaces the slide for smear or gram staining

Please review and incorporate into your practice the revised DSTs as they outline the current requirements for CRNBC Sexually Transmitted Infections Management Certified Practice.

More detailed information about the revisions can be found on the BCCDC SmartSex blog.
