A multi-site clinical study was conducted from September 1, 2021 to October 17, 2023, at six geographically diverse sites across the U.S. In this study, the First To Know Syphilis Test was used by 1270 people, with results compared to a combination of three FDA-cleared tests. The First To Know Syphilis Test correctly identified 93.4% of positive specimens (99 out of 106) and 99.5% of negative specimens (1158 out of 1164).

The First To Know Syphilis Test is the only in-home syphilis test where the results are generated by the user—not a healthcare provider. The test is easy to use and does not require you to mix any liquids or count any drops. Using the included lancet device, obtain 1-3 drops of blood from your finger. Touch the test cartridge to your finger, allowing the blood to enter the cartridge. Tap the cartridge twice and lay it flat. Get your result in just 15 minutes. 


Test usability was assessed in two studies. For the first, all 1345 participants enrolled in clinical study were observed while performing testing and difficulties were noted. A second study enrolled 20 participants to assess lay users’ execution of the First To Know Syphilis Test workflow using the written instructions alone. Following both studies, a questionnaire was issued to participants to assess ease of use. The results of both studies demonstrated that the First To Know Syphilis Test is easy to use by lay users.

User label comprehension was assessed using two sets of questionnaires. One questionnaire was issued to all 1345 participants following the clinical study. A second questionnaire was issued to all 20 participants following the second usability study plus an additional 20 participants (total of 40 participants). Both questionnaires were aimed at evaluating users’ understanding of key communication messages (e.g., FAQ messages and warnings) found in the labeling. The results of user label comprehension demonstrated that the First To Know Syphilis Test labeling is easy to understand by lay users.
