- Storage/Transport Temperature
- Unacceptable Conditions

|Test Code||Components||Reference Interval|
|T.Pallidum Ab, IgG (FTA-ABS)||Nonreactive|
|0050777||Treponema pallidum Antibody by TP-PA||Nonreactive|
The FTA test is not recommended for cerebrospinal fluid specimens. For CSF specimens, the VDRL-CSF test is recommended.
Inconclusive results will be repeated by TP-PA to aid the physician in diagnosis. Inconclusive final reports indicate the initial specimen submitted has been tested twice and cannot be interpreted as either reactive or nonreactive. If it is the second specimen submitted on a patient and the report is again inconclusive, it is impossible to state definitively that the patient does or does not have syphilitic infection.
Reflex will only happen when the FTA is found to be inconclusive. Additional charges apply.
