The benefit of having a SARS-CoV-2 antigen test available
The SARS-CoV-2 virus causes respiratory tract infection. It is transmitted mainly via respiratory droplets after close contact, and primary viral replication is presumed to occur in mucosal epithelium of the upper respiratory tract (nasal cavity and pharynx).1 At these locations viral load peaks within the first week after symptom onset, and then declines.2
A SARS-CoV-2 antigen test detects the presence of the SARS-CoV-2 virus from part of the upper respiratory tract swab specimens by identifying a nucleoprotein that is carried by the virus. The test identifies current infection during the acute phase of COVID-19, while the virus is still present in large quantities in the respiratory tract.
At Roche Diagnostics we believe wide accessibility to such high-performance, instrument-free and reliable Point of Care tests can contribute significantly to better managing the ongoing pandemic crisis.
Features and benefits of the SARS-CoV-2 Rapid Antigen Test Nasal
In comparison to the existing Roche SARS-CoV-2 Rapid Antigen Test, the SARS-CoV-2 Rapid Antigen Test Nasal collects the sample from the front area of the nose instead of the nasopharynx, resulting in a simplified and faster testing procedure.1 This testing method can help reduce overall patient discomfort, particularly in sensitive individuals such as children, elderly people and/or people with disabilities.
Besides being less invasive, the test also provides patients with the option to self-collect their nasal sample under the supervision of a healthcare professional. Through reduced physical contact, this method of testing can help to decrease the risk of exposure to the virus for healthcare professionals. Whether the test could also be used without supervision of a healthcare professional will depend on local regulatory requirements.
The benefits of the SARS-CoV-2 Rapid Antigen Test Nasal in short:
- Using a nasal swab for quick and convenient specimen collection
- Getting a quick result within 15-30 minutes – no need for a follow-up appointment to discuss the result
- Providing patients with the option to self-collect their nasal sample
- Allowing decentralized testing or access to testing in areas where laboratory testing is not available.
