Brief Summary

The AudibleHealth Dx is a diagnostic software as a medical device (Dx SaMD) consisting of an ensemble of software subroutines that interacts with a proprietary database of Signal Data Signatures (SDS), using Artificial Intelligence/Machine Learning (AI/ML) to analyze forced cough vocalization signal data signatures (FCV-SDS) for diagnostic purposes. This study will evaluate the performance of the AudibleHealth Dx in comparison to a standard of care Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) test for the diagnosis of COVID-19. A secondary purpose of the study will be usability testing of the device for participants and providers.

  To demonstrate non-inferiority of the positive percent agreement (PPA) of the AudibleHealth Dx when compared to FDA approved SARS CoV-2 RT-PCR testing for the diagnosis of COVID-19 illness

  Participants will have a single encounter lasting less than one hour; anticipated study duration is 6 weeks. Target enrollment is 65 positive and 152 negative participants.

• Non-inferiority of the negative percent agreement (NPA)

  2\. To demonstrate non-inferiority of the negative percent agreement (NPA) of the AudibleHealth Dx when compared to FDA approved SARS-CoV-2 RT-PCR testing for the diagnosis of COVID-19 illness.

  Participants will have a single encounter lasting less than one hour; anticipated study duration is 6 weeks. Target enrollment is 65 positive and 152 negative participants.

Study Arms (1)

Trial Population

The trial population will be enrolled from adults presenting for elective, outpatient COVID-19 testing at a single center, potentially with multiple testing locations (subject to local needs at the time of the trial). The investigational device will be provided to Participants via a cell phone preloaded with Common off-the-shelf original equipment manufacturer (COTS OEM) software and the investigational Dx SaMD. The investigational device will be evaluated during a single encounter in which an FCV-SDS will be collected. No follow-up visits or participant contacts will be involved in this trial.

Interventions

Diagnostic Test: Diagnostic Software as Medical Device DEVICE

AudibleHealth Dx is an investigational Dx SaMD consisting of an ensemble of software subroutines that interacts with a proprietary database of signal data signatures (SDS) using Artificial Intelligence/Machine Learning (AI/ML) to analyze forced cough vocalization signal data signatures (FCV-SDS) for diagnostic purposes. The intended use for the AudibleHealth Dx AI/ML-based Dx SaMD using FCV-SDS is for the diagnosis of acute and chronic illnesses, specifically COVID-19 illness for this study.

Trial Population

Eligibility Criteria

• Age: 18 Years - 100 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Adults seeking elective, outpatient COVID RT-PCR testing will be included.

You may qualify if:

• years of age or older
• Present for elective, outpatient COVID-19 RT-PCR testing
• Meet the FDA EUA approved indications for use for RT-PCR nasal swab testing for COVID-19
• Stated willingness to comply with all trial procedures and availability for the duration of the trial
• Informed consent must be obtained prior to testing
• Ability to complete both the informed consent form and the screens on the medical device app in English (no translation to other languages is currently available)

You may not qualify if:

• Any individual who was a part of the AudibleHealth Dx Development, Training, and Usability trial (Training and test data sets are to be kept strictly separate.)
• Less than 18 years of age
• Unable to produce a voluntary forced cough vocalization (FCV)
• Recent acute traumatic injury to the head, neck, throat, chest, abdomen or trunk
• Patent tracheostomy stoma
• Recent chest / abdomen / trunk trauma or surgery, recent / persistent neurovascular injury or recent intracranial surgery
• Medical history of cribriform plate injury or cribriform plate surgery, diaphragmatic hernia, external beam neck / throat / maxillofacial radiation, phrenic nerve injury/palsy, radical neck / throat / maxillofacial surgery, vocal cord trauma or nodules
• Since persons with aphasia may have difficulty in producing an FCV-SDS in the time allotted by the app, this population also will be excluded from the current trial
