Fasting Required: No
Specimen: Blood
Results: 3 – 5 Business days
Methodology: Immunofluorescent Assay (IFA)
Alternate Names: Treponemal pallidum, Fluorescent Treponemal Antigen, Syphilis
Description: This test is done routinely to confirm whether a positive screening test for syphilis (either VDRL or RPR) means you have a current syphilis infection. It may also be done when other syphilis tests are negative, to rule out a possible false-negative result.
Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
