In brief: Screening tests.

Vdrl (venerial disease research laboratory) tests against anti-cardiolipin antibodies and RPR (papid plasma reagin) tests against nonspecific antibodies suggestive of syphilis and are screening tests.
Treponemal antibody tests, like fta-abs and mha-tp usually become positive two to five weeks after the initial infection. These are used to confirm syphilis and stay positive, even after therapy.

In brief: Positive tests

You may want to follow them up with more specific tests, or your physician may simply treat depending on history.
