WebJan 19, 2024 · FTA-ABS is the most sensitive test in all stages of syphilis, and is the best confirmatory test for a serum reactive to a screen such as RPR or VDRL. FTA-ABS antibodies rise more quickly in primary syphilis and remain positive in tertiary syphilis. In late syphilis, approximately 1/3 of these patients may have a nonreactive VDRL or RPR.
