aDETECT: Diagnostic Evaluation To Expand Critical Testing Technologies.

bPHSKC: Public Health–Seattle & King County.

cSTD: sexually transmitted disease.

dThere are 27 Project DETECT part 2–group 1 participant visits that were recruited for Project DETECT based on anecdotal evidence of reported sex with men. There is no data evidence of reported sex with men but were included in the Project DETECT part 2–group 1–eligible PHSKC STD Clinic population because they enrolled in Project DETECT.

ePersons who identified as Hispanic or Latinx ethnicity were classified as Hispanic/Latinx regardless of race.

fTransgender women and transgender men have higher rates of misclassification due to inconsistent reports of sex at birth and current gender identity between the PHSKC STD Clinic kiosk and medical record.

g“HIV follow-up visit” was removed as a response option in December 2018.
