This clinical study aims to train the algorithm and assess the performance of the Ainos Flora Women's Vaginal Health Tester in identifying vaginal infections.
Ainos Flora Women's Vaginal Health Tester is an in vitro diagnostic device implementing electronic nose technology to detect vaginal infections by examining metabolized gases of vaginal bacteria. The electronic nose system mainly comprises the Micro-Electro-Mechanical Systems (MEMS) gas sensor array and the Artificial Neural Network algorithm. The primary purpose of this study is to train the algorithm and assess the performance of the Ainos Flora in identifying vaginal infections. In addition, the primary outcome measures of this study, including sensitivity and specificity, will be used as a reference for the feasibility and sample size assessment of the next phase of pivotal clinical trials.

| Measure | Description | Time Frame |
|---|---|---|
| To assess the sensitivity and specificity of Ainos Flora in subjects compared to RT-PCR and culture groups in identifying the types of vaginitis. |
| Up to 6 months. |
| Measure | Description | Time Frame |
|---|---|---|
| Assess the change in sensitivity as the number of subjects is changed. | When the number of subjects reaches 30,60,90,120, input the collected gas data into the algorithm and calculate the sensitivity. We can then assess the change in sensitivity when the number of subjects changes from 30 to 60, 90, and 120. | Up to 6 months. |

This clinical study is a prospective study to evaluate the sensitivity and specificity of the Ainos Flora Female Vaginal Health Tester in identifying vaginal infections. Potential subjects will be patients in the gynecological clinic. The study will evaluate the performance of the Ainos Flora Female Vaginal Health Tester by comparing it to the conventional real-time polymerase chain reaction (RT-PCR) and culture methods for the diagnosis of vaginitis to calculate both sensitivity and specificity.
