Background: GetCheckedOnline (GCO) is a comprehensive internet‐based STI/HIV testing service that launched in fall 2014 in Vancouver, Canada. During the pilot phase (2014‐15), clients accessed GCO through three methods: invitation to participate as clients of a major urban STI clinic (“clinic invitees”); access code provided when turned away from the clinic when at capacity (“turn‐aways”); access code promoted through a campaign to gay and bisexual men (“GBM campaign”). We compared uptake of GCO through the various steps in the testing process across these three promotional strategies.

Methods: We calculated the number and proportion of unique clients for each of the following steps: account created; lab form created; specimens submitted; positive result; repeat testing. Proportions were compared across promotional streams and by sociodemographic characteristics using Chi‐square tests to identify significant differences.

Results: 868 clients created GCO accounts between September 2014 and December 2015; 56% created a lab form and 61% of those clients submitted specimens. Of clients submitting specimens, 3% had a positive result (4 chlamydia, 2 gonorrhea, 2 syphilis) and 22% tested more than one time. Turn‐away clients were more likely to create lab forms (81%, p<0.05) and submit specimens (72%, p<0.05). 71% of clients were male, 74% were white, and 30% were from suburban regions; characteristics did not differ between clients who created accounts and those who submitted specimens.

Conclusions: Attrition through the steps of this online testing service was lower among turn‐away clients, suggesting this group is particularly motivated to use an online STI/HIV testing service. The absence of differences in uptake by sociodemographic characteristics underscores the service’s broad appeal.
