A Study to Evaluate the Performance, Usability, and Contrived Result Interpretation of iStatis Gonorrhea Antigen Test

The study is designed to evaluate iStatis Gonorrhea Test performance when used by trained personnel as follows:

• A method comparison will be performed to determine the diagnostic sensitivity and specificity of the iStatis Gonorrhea Test compared to a reference test that is an approved, current on-market Gonorrhea/Chlamydia combo assay, Cobas CT/NG.
• To evaluate the usability of iStatis Gonorrhea Test by means of assessing user experience via a questionnaire in combination with the success in performing the test. A minimum of 15 intended users to participate in the usability evaluation.
• To evaluate and document whether intended users (trained personnel), a minimum of 15 intended users across a minimum of three (3) sites, can successfully interpret contrived iStatis Gonorrhea Test results that include - strong positive, weak positive, negative and a range of invalid results.
