The study is designed to demonstrate suitability of the Dräger Antigen Test for SARS-CoV-2 detection in clinical nasal specimens. Real-time polymerase chain reaction (RT-PCR) on specimens collected by pharyngeal swabs serves as a reference method.
The Dräger Antigen Test SARS-CoV-2 is a rapid lateral flow immunoassay for the qualitative
detection of SARS-CoV-2 nucleoprotein directly from less invasive nasal swabs, to be
performed at the point of care. The test kit contains all components required to carry out a
test detecting SARS-CoV-2 nucleoprotein.
The study is designed to demonstrate suitability of the Dräger Antigen Test for SARS-CoV-2
detection in clinical nasal specimens. Real-time polymerase chain reaction (RT-PCR) on
specimens collected by pharyngeal swabs serves as a reference method.
The goal of the study is to compare Dräger test results to the corresponding PCR data for
overall sensitivity and specificity. Specimens are collected from patients showing COVID-19
symptoms as well as asymptomatic participants. Participants are recruited across all genders
and eligible age groups. Study staff records participants' information such as symptoms and
time since symptom onset. For each study participant, the specimen for RT-PCR is collected
first, then the Dräger test specimen. The Dräger test result is read after 15 min to 20 min.
Diagnostic Test: Dräger Antigen Test SARS-CoV-2
Collection of patient samples using the Dräger sample collector with subsequent test reading via the Dräger Antigen SARS-CoV-2 Test
Inclusion Criteria:
- Participants must require SARS-CoV-2 testing for the following reasons:
- COVID-19 symptoms (Fever, cough and/or sore throat, fatigue/ general feeling of
weakness, loss of sense of smell and/or taste, shortness of breath, muscle
stiffness/ body aches, head cold/ running nose, etc.) on the day of testing, or
- Known or suspected exposure to SARS-CoV-2 (contact persons etc.), or
- Member of a group of high risk of exposure such as healthcare workers etc., or
- Require screening for any other reason, e.g. doctor's orders, hygiene directive
etc.
- Participant must be of legal age and must be able to understand the procedure and
letter of consent.
Exclusion Criteria:
- Patients younger than 18 years old are excluded from the study.
- Pregnant or breastfeeding patients are excluded from the study.
- Patients unable to provide written informed consent are excluded.
- Patients with bleeding disorder are excluded from the study as a precaution.
- Hospitalized patients/inpatients are excluded.
- Application of nasal spray within 15 min prior to testing.
- Participants with symptoms on the day of testing are excluded, if any of their
symptoms started more than 14 days prior to testing.
- Asymptomatic participants are excluded, if they experienced any symptoms in the 14
days prior to testing.
