FTA-ABS test
Alternate Names : Fluorescent treponemal antibody absorption test
Normal Values
A negative or nonreactive result means there is no current or past infection with syphilis.
What do Abnormal Results Mean?
A positive FTA-ABS usually indicates infection with syphilis. This test result will remain positive for life even if syphilis has been adequately treated. Therefore, it cannot be used to monitor the treatment of syphilis.
Other illnesses such as yaws and pinta may also result in positive FTA-ABS results. Occasionally there can be a false positive result, most often in women with lupus.
