Which screening tests are used for both active and latent Syphilis infections? (Choose 2)

The screening tests for both active and latent syphilis infections include the FTA-ABS and MHA-TP.

The FTA-ABS, or Fluorescent Treponemal Antibody Absorption test, is a treponemal test that detects antibodies specific to Treponema pallidum, the causative agent of syphilis. This test is effective in confirming syphilis infections, regardless of whether the infection is active or latent. It remains positive for life after infection, making it useful for identifying past exposures.

Similarly, the MHA-TP, or Microhemagglutination Assay for Treponema pallidum, is another treponemal test that assesses for antibodies against T. pallidum. Like the FTA-ABS, it can indicate both an active and latent infection, as it identifies antibodies that remain in the body even after the infection is treated.

In contrast, tests such as RPR (Rapid Plasma Reagin) and VDRL (Venereal Disease Research Laboratory) are non-treponemal tests. These are mainly used for screening active infections, as they detect non-specific antibodies that may not be present in latent infections. Therefore, while R
