The Feasibility of Implementing Syphilis Point-of-care Testing Into a Prenatal Clinic for People Facing Barriers to Care

The goal of this clinical trial is to learn if a finger-prick blood test for rapid diagnosis of syphilis infection can be implemented in a low-barrier prenatal clinic for people at risk of syphilis in pregnancy. The test gives results in 5 minutes and also tests for HIV. The main questions the study aims to answer are: * How often do pregnant people at risk of syphilis agree to the rapid test? * How well do healthcare providers perform the rapid test? * Does the rapid test speed up diagnosis and treatment of syphilis in pregnant people and their sexual partners? Participants will: * Give feedback about why they did or did not want to take the rapid test, and what their experience was taking the test; and * Share information about their health, pregnancy, and syphilis treatment (if applicable).
