In the fluorescent treponemal antibody absorption (FTA-ABS) test, what is the purpose of absorption with Reiter treponemes? a. It removes reactivity with lupus antibody. b. It prevents Treponemal method A serological test for syphilis The acronym stands for fluorescent treponemal antibody-absorption test.
