Latent syphilis is a stage of syphilis infection where the bacteria Treponema pallidum remains in the body but causes no visible symptoms. It is caused by untreated primary or secondary syphilis that progresses to a silent phase that can last for years. The Syphilis Antibody Cascading Reflex test is the most important test for diagnosis because it detects antibodies even when no symptoms are present.

Latent syphilis is caused by the bacteria Treponema pallidum that remains dormant in your body after the initial infection phases. When primary or secondary syphilis goes untreated or is inadequately treated, the bacteria enter a hidden phase where they continue to live in your body without causing noticeable symptoms. During this silent stage, the infection can still be detected through blood tests and may be transmitted to sexual partners or from mother to baby during pregnancy, even though you feel completely healthy.
The Syphilis Antibody Cascading Reflex test is the most important test for latent syphilis because it detects specific antibodies your immune system produces in response to Treponema pallidum infection. This comprehensive test uses a cascading approach that starts with a screening test and automatically performs confirmatory tests if initial results are positive, ensuring accurate detection even when no symptoms are present. Since latent syphilis produces no visible signs, blood antibody testing is the only reliable way to diagnose this hidden infection and determine if treatment is needed to prevent progression to serious complications.
You should get tested if you have had unprotected sex with someone who might have syphilis, if you have been diagnosed with another sexually transmitted infection, if you are pregnant or planning to become pregnant, or if you received treatment for syphilis in the past and need follow-up testing. Testing is also important if you have multiple sexual partners or if a sexual partner recently tested positive for syphilis, even if you feel perfectly fine. Because latent syphilis has no symptoms, regular screening is the only way to catch this hidden infection before it progresses to more serious stages.
