The Evolution of STI Testing: A Catalyst for Modern Diagnostic Technologies
Although blood-based assays still account for much of the at-home testing market, the rapid uptake of urine, oral fluid and other alternative specimen types is widening the range of tests that can be performed outside clinical settings. The shift toward these more diverse sample types is increasingly shaping the at-home testing market. Developers such as OraSure Technologies, bioLytical Laboratories, Wondfo, LetsGetChecked, BioSure and Everlywell now account for roughly 35% of global market share, 10 reflecting a move toward designs that emphasize ease of use, comfort and accessibility.
user-friendly assays that minimize error, streamline the testing process and make at-home sexual health screening more accessible to a broader population. Shifts in Sample Types and Industry Players Digitally-enabled testing models from companies such as Everlywell and LetsGetChecked are also reshaping how people access sexual health care. By allowing individuals to order kits, collect samples at home and receive certified laboratory results online, these services are helping to normalize home-based screening and reduce traditional barriers to testing.
Self-Collection with Lab Testing: Hybrid Accuracy and Accessibility
Self-collection with lab testing combines the convenience of at-home sampling with the accuracy of centralized laboratory analysis. In this hybrid model, individuals collect at-home specimens such as urine, and vaginal or throat swabs, and mail them to a certified lab for testing on validated molecular or immunoassay platforms. This approach reduces logistical barriers, particularly in remote regions with limited clinic access and transportation challenges. It supports privacy and autonomy without requiring individuals to conduct or manage the test entirely on their own. Adoption of self-sampling accelerated during the COVID-19 pandemic, normalizing its role as a practical and accepted approach to remote testing and specimen collection. For example, England’s National Chlamydia Screening Programme, which began offering online test ordering in 2015, saw the share of its tests initiated through the internet
