Comments | |||||
Acceptable initial screening test for syphilis, as well as for monitoring treatment response in established syphilis. SHL follows the reverse algorithm for syphilis testing, meaning that we begin with a treponemal test, Treponema pallidum Antibody (Syphilis)(Serum). This test is to be ordered for confirmation of a non-treponemal test performed by the submitter and it will NOT be reflexed to the nontreponemal test, Syphilis VDRL (Serum). | |||||
