A Study to Evaluate the Performance, Usability, and Contrived Result Interpretation of iStatis Gonorrhea Antigen Test
A Study to Evaluate the Performance, Usability, and Contrived Result Interpretation of iStatis Gonorrhea Antigen Test by Trained Personnel at Near-Patient or Point-of-Care Settings
The objective of this study is to evaluate the performance, usability, and contrived result interpretation of iStatis Gonorrhea Antigen Test (iStatis Gonorrhea Test) in the intended near-patient or point-of-care setting by trained personnel.

Detaljerad beskrivning
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.

Experimentell: iStatis Gonorrhea Test Performance (Operator-collected swabs)
Operator-collected vaginal swabs will be tested on the iStatis Gonorrhea Test |
Vaginal swabs are tested on the iStatis Gonorrhea Antigen Test |

Experimentell: iStatis Gonorrhea Test Performance (Self-collected swabs)
Self-collected vaginal swabs will be tested on the iStatis Gonorrhea Test. Participants assigned to the self-collection arm of the study will complete the self-collection Usability Questionnaire |
Vaginal swabs are tested on the iStatis Gonorrhea Antigen Test |

Inget ingripande: Reference Test to evaluate iStatis Performance
Vaginal swabs collected for reference testing will be tested using the Cobas CT/NG reference assay to determine the gonorrhea infection status of participants. |

Performance Evaluation
Tidsram: 3 months
|
The performance between iStatis Gonorrhea Test and the reference test result for vaginal swabs (operator-collected and self-collected) will be calculated for all sites combined. Diagnostic sensitivity and specificity values and 95% CIs will be calculated for all subjects combined. The percentage of invalids (tests that fail to produce a control dot with accurate use) will be identified and reported. |

iStatis Gonorrhea Test usability evaluation
Tidsram: 3 months
|
Overall test usability and self collection usability will be determined via a questionnaire completed by trained personnel who used the device during testing and study participants that performed sample self-collection respectively. The usability questionnaire will use a scale of one (1) to 5 (1 - very difficult/very unlikely to 5 - very easy/very likely), with a rating of 3 being satisfactory. |

iStatis Gonorrhea Test contrived result interpretation evaluation
Tidsram: 3 months
|
Trained operators will evaluate a panel of contrived (mock) iStatis devices. These devices are designed to represent a comprehensive range of test outcomes, including strong positives, weak positives, negatives and invalid results. Operators will interpret the results of the mock devices and record their interpretations which will be compared to the correct interpretation of the device. |
