FTA (fluorescent treponemal antibody) is a confirmatory test used in
the diagnosis of syphilis, typically conducted after an initial positive
screening test. Painless sores (chancre) at the infection site characterize the
primary stage of syphilis. In the secondary stage, symptoms include skin
rashes, mucous membrane lesions, fever, and flu-like symptoms. The latent stage
is asymptomatic, representing a dormant period, while the tertiary stage
involves severe complications affecting various organs, potentially leading to
neurosyphilis. Timely medical intervention is crucial for effective treatment
and preventing complications at different stages of syphilis. Regular testing
aids in early detection and management.
