Serology

Treponema pallidum subspecies pallidum

Syphilis Diagnostics and Vaccine Preventable Bacterial Diseases

• Syphilis

CSF – minimum of 0.5 mL. The same CSF sample is used in the FTA-ABS on CSF test, the VDRL-CSF test and molecular detection by conventional PCR.

Specimens may be subject to rejection if they are not the appropriate sample type, have insufficient volume, or are not accompanied by relevant patient information.

N/A

Store samples refrigerated or frozen until shipped for testing. Ship frozen samples on dry ice, and refrigerated samples on wet ice
