Reference Details


Molecular detection and genotyping of azithromycin resistant Treponema pallidum using conventional PCR and DNA sequencing.

Test Category:
Molecular Detection and Genotyping
Treponema pallidum subspecies pallidum
Illnesses and Diseases:
  • Syphilis

Swab, cerebrospinal fluid (CSF) or whole blood. Minimum of 0.5 mL of CSF. Minimum of 0.5 mL of whole blood.

Collection Method:

Use appropriate swab, such as Rayon or Dacron swabs to obtain specimens from ulcers.

Specimen Processing, Storage and Shipping:

Swabs can be shipped dry or in appropriate transport medium, such as viral transport medium.  Store samples refrigerated or frozen until shipped for testing.  Ship frozen samples on dry ice, and refrigerated samples on wet ice.

Transportation of Dangerous Goods:

Shipping of specimens shall be done by a TDG certified individual in accordance with TDG regulations. For additional information regarding classification of specimens for the purposes of shipping, consult either Part 2 Appendix 3 of the TDG Regulations or section 3.6.2 of the IATA Dangerous Goods Regulations as applicable.

Suspected of syphilis infection.

Accompanying Documentation:

Completed Syphilis requisition form including sender lab name, address and telephone number. Patient identifier (specimen reference #), date of birth and sex. Date collected and test requested.


Specimens that are positive by molecular detection using conventional PCR are genotyped to determine if they are resistant to azithromycin.

Methods and Interpretation of Results:

For research purposes only.

Turnaround Time:

20 calendar days.
