What is Fluorescent Treponemal Antibody Absorption (FTA-ABS)?
Fluorescent Treponemal Antibody Absorption (FTA-ABS) is a serological test primarily used for the detection of antibodies against Treponema pallidum, the bacterium that causes syphilis. It utilizes fluorescence microscopy to identify the presence of specific antibodies by binding them to fluorescent-labeled antigens.
