- Diagnostic Test: Testing Sensitivity for SARS-CoV-2 Virus in Symptomatic Individuals
This is an operational project. Patients will collect a sample from the tongue, nasal cavity and MT and then clinicians will collect a NP sample from the nostril corresponding to each participant's dominant hand.
- Accuracy of patient administered tests [ Time Frame: 2 weeks ]compare clinician collected nasopharyngeal (NP) samples to patient-obtained tongue, nasal and mid-turbinate (MT) samples in the detection of SARS-CoV-2 in an outpatient clinic setting
Biospecimen Retention: None Retained

Plan Description: | All patients who participate in this operational pilot will have standard COVID-19 screening information entered into their electronic medical record. The collection locations and source of collection (medical personnel versus patient) will need to be clearly distinguished for the purposes of this project. Data resulting from analysis of the samples will also be stored in the electronic medical record and any positive results will be reported accordingly to public health officials as required. The data collected due to this operational effort will be extracted from the medical record and stored for additional research analysis to demonstrate equivalence between location in the nose for the collection of the sample and similarity between sample collected by medical personnel and samples collected by the patient. Data will be shared between the participating clinics, UHG and collaborating partners performing the analysis of the samples and returning results. |
