Despite national testing guidelines, rates of testing for HIV, sexually transmitted infections, and hepatitis C remain lower than recommended for men who have sex with men (MSM) in the US. To help address this, the TakeMeHome (TMH) program was started in March 2020 by a consortium of public health organizations and dating apps - Building Healthy Online Communities - to work with health departments to increase access to HIV testing for MSM on dating apps. Users of participating dating apps were sent messages about opportunities for testing with self-collected specimens through TMH. Program users were eligible to receive test kits if they lived in a participating zip code and were aged at least 18. Users who were interested in testing could order kits to be mailed to them for lab-based testing of HIV, hepatitis C, chlamydia, gonorrhea, and/or syphilis, depending on risk and availability in their zip code. Orders were sent via application programming interface (API) to Molecular Testing Labs (MTL) for fulfillment; kits were provided at no cost to the program user. Within approximately 24 hours of order receipt, MTL mailed program users a kit with required collection supplies, directions, and a link to a video instruction for self-collection. Program users received an automated email after testing was complete with a link to access results through their online account. Individuals with positive results on any of the relevant tests were directed to additional information and supported with linkage to additional testing or treatment, depending on local protocols. The positivity rate of specimens processed through TMH was 1.4% for HIV, 0.6% for hepatitis C, and 2.9% for all STIs combined. The per-person positivity rate was 15.3% across all STIs.Conclusions: The TakeMeHome program demonstrates that self-collected lab-processed testing is feasible and effective at identifying new HIV and STI cases.
