简要总结
Can Nanotechnology Biomarker Tagging (NBT) be used to detect COVID-19 infection in people presenting for COVID-19 testing?
NBT can be used to detect the substances present in a person's breath. In this study the breath of people presenting for COVID-19 testing is going to be analysed. Analysing a large number of samples from people with COVID-19 (as confirmed by the standard swab test used by the NHS) will enable a breath profile to be produced, ie the substances present in the breath when someone has COVID-19. After the profile has been validated, NBT can be used to test whether or not a person has COVID-19 by seeing if their breath matches the profile.
Using this technology for COVID-19 testing has advantages over the current standard test. The sample can be analysed immediately in the clinical setting and the results are available in 5-10 minutes, so if the person tests negative they can go back to their normal life straight away. The current swab test takes around 72 hours for the results to be available, and the person needs to self-isolate during this time in case they test positive, resulting in potentially unnecessary days of work missed and inconvenience. The breath test is non-invasive and is unlikely to cause any discomfort, as the person is only required to breath normally into the device. This study will also review the practicalities of using this test. It is quick and easy to train people in how to carry out the test, so it could potentially easily be rolled out to testing sites.
详细描述
This is a Cohort Study which will collect non-invasive, expired breath sample, cheek swab and a Medical and Lifestyle questionnaire from participants.
When the participant presents for COVID-19 testing they will be asked to provide a cheek swab and breath sample, and complete the study questionnaire. They will not need to give any identifiable information or have a second visit. The samples will be analysed immediately and disposed of as clinical waste. ANCON will then use the data to build a breath profile of COVID-19 infection.
Sample and data collection method for inpatients:
- Sequential (daily or every other day as able) breath and swab test will be taken from some of the patients admitted in the hospital (inpatients).
- This will be taken from entry or start of the study to discharge or end of study or until patient or medical staff deem unsuitable to continue
- This will enable to track infection and the relevant profile changes as covid-19 progresses and/or is treated. This will provide vital additional information around identifiers associated with the disease and its progress.
Anonymous Questionnaire - Each participant will be asked questions in the form of a short standard questionnaire based on:

结局指标
主要结局
To investigate/ examine the effectiveness of Nanotechnology Biomarker Tagging (NBT) in detecting COVID-19 infection using breath samples of patients with COVID-19 symptoms
时间窗: 6 Months
This will be measured by identification of VOCs present in the breath sample of the COVID-19 positive and their relative concentrations compared to a COVID-19 negative breath sample. These will be combined to provide a COVID-19 positive profile
次要结局
- -To profile the unique pattern of Volatile Organic Compounds (VOCs) found in the expired breath of COVID-19 patients using the NBT system (VOC analysis and ML).(6 months)
- To differentiate this unique profile from the patients that are found to be negative for COVID-19(6 months)
