SARS-CoV-2 Antigen Self Test Nasal

Testing in your hands

The SARS-CoV-2 Antigen Self Test Nasal provides reliable results for individuals suspected of having COVID-19. The Self Test can be performed by the general public, providing another option for decentralized testing. Testing whenever and wherever needed can be the basis for safer decision making and a step towards more normality for everyone.

An aid in identifying individuals infected by SARS-CoV-2¹

The SARS‐CoV‐2 Antigen Self Test Nasal is a lateral flow test for the qualitative detection of SARS‐CoV‐2 nucleocapsid antigen in human nasal samples. This test is used to detect antigens of the SARS‐CoV‐2 virus in individuals suspected of having COVID‐19 and is designed as a self‐test for the general public.

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).² At these locations viral load peaks within the first week after symptom onset, and then declines.³

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.

The key benefits of the SARS-CoV-2 Antigen Self Test Nasal

The benefits for society, healthcare systems and workers:

Testing is possible everywhere: Decentralized testing minimizes the possibility of exposure of healthcare workers to potentially infected individuals while protecting healthcare capacity.
A tool to safely re-open the economy: Tested individuals might be able to travel and participate in events, while reducing the risk of spreading the virus.
Real-world evidence: Independent performance studies with large sample sizes, including professional collection, self-collection and self-testing groups.

The benefits for the general public:

Reliable answers: High test quality and performance.¹
Quick results: Faster results compared to laboratory testing.
Easy repetitive testing: No need to visit a healthcare professional or schedule an appointment.
Easy handling procedure: Reduced handling errors and waste.
Increased user protection: Virus inactivation by extraction buffer after 2 minutes.
Peace of mind: Worrying symptoms can be put into perspective.

Testing the quick and easy way

Testing process for the SARS-CoV-2 Antigen Self Test Nasal¹

Make sure to follow the steps below carefully

Preparing for a test

Always read the Instructions for Use carefully.

Wash your hands...

... or use hand sanitizer.

Place the needed material in front of you.

Keep a timer to track the readout time.

Collecting and preparing the nasal sample

Always read the Instructions for Use carefully.

Collect Nasal Sample

Blow your nose once using a tissue. Open swab packet and make sure to only hold the swab at the bottom. Do not touch the tip. Insert the sterile swab 2 cm into your nostril and rotate the swab 4 times for about 15 seconds against the nasal wall.

Repeat process

in the other nostril with the same swab.

Prepare the sample

Insert the swab into the extraction buffer tube, squeeze the tube tight at the bottom and stir the swab more than ten times.

Remove the swab

while squeezing the sides of the tube. Press the nozzle cap tightly onto the tube.

Performing the test

Always read the Instructions for Use carefully.

Add 4 drops of extracted sample to the specimen well of the test device.

Set timer and read the results after 15 minutes and before 30 minutes have passed.

Risk of incorrect results. Do not read test result after 30 minutes.

Interpreting the results

10 - 15 min

Control line C

Confirms the test is working correctly

Test line T

Visible if SARS-CoV-2 antigen was detected

Positive

Negative

Invalid

Positive test result

If both the colored line C and T are visible the test result is positive. This means the test detected the virus protein in the sample. The tested person is likely infected with SARS-CoV-2.

What now?

You need to self-isolate immediately.

Contact your doctor and...

... you may be required to undergo a PCR test to confirm the test result.

Negative test result

A visible control line C means the test worked correctly. The test result is negative. There was no virus protein detected in the sample.

What now?

There is a very low chance you are currently infectious to others.

Note that this result is only valid for the day you take the test.

Continue to follow the hygiene guidelines.

Invalid test result

If there is no line visible, or only the line marked with a T, the test did not work correctly and needs to be repeated with another test device.

What now?

To get a valid result you will have to do a new test (with new test material and new sample).

Make sure to follow the instructions carefully.
