How fast can syphilis be detected




















The most specific test for confirming syphilis is the Fluorescent Treponemal antibody absorption FTA-ABS test, which uses a fluorescent marker to identify T pallidum antibodies in a blood or spinal fluid sample. The enzyme immunoassay EIA test checks blood using antibodies specific to syphilis infection to locate syphilis antigens. With blood testing, syphilis can be detected as early as 1 to 2 weeks after exposure.

The highest accuracy can be expected within about three months, with false positive results possible any time within the initial 90 days after infection. People who have suffered from a syphilis infection in the past could also have a false positive result due to syphilis antibodies lingering in the bloodstream. If a reliable testing method returns a negative result 90 days or later after exposure, it is considered a negative diagnosis. Syphilis is easily cured using antibiotics if treated appropriately during its early stages.

During the early stages of syphilis infection, a single dose of penicillin is effective to treat and cure syphilis. In later stages, a higher dosage is necessary. The physical and neurological harm, such as heart or nervous system damage typical of the third stage of syphilis, cannot be reversed. If the person seeking treatment is allergic to penicillin, azithromycin or doxycycline can be prescribed instead.

For a year after treatment, a regular schedule of follow-up tests is required. Nick Corlis is a writer, marketer, and designer.
