Intended use

The SARS‑CoV‑2 Antigen Self Test Nasal is a so-called 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.
It is designed as a self‑test for patients. For best performance, it is recommended this test be used within 7 days post-onset of symptoms.
Any COVID-19 variants in circulation as of 13 September 2021 are detected by this test without any impact on performance.

Summary

At the end of 2019, a novel virus was discovered in a cluster of pneumonia cases.1 This virus belongs to the large family of Coronaviruses and has been named SARS‑CoV‑2 because its genetic sequence is closely related to the virus that caused the SARS outbreak in 2013.2 The disease caused by SARS‑CoV‑2 is called COVID‑19 (COronaVIrus Disease 2019).3,4 The course of SARS‑CoV‑2 infections can vary widely. Some infected individuals do not have any symptoms, others experience relatively mild symptoms such as fever, cough, loss of taste or smell, or diarrhea. But it can also cause more serious symptoms such as difficulty in breathing or even death.5,6 Usually, it takes 5 – 6 days for symptoms to develop after exposure to SARS‑CoV‑2, but sometimes it can take as long as 14 days.6

Reagents

Precautions and warnings

Use the test kit once only. Do not reuse the test strip or buffer.
Remove the test device from the sealed pouch only when you are ready to perform the test.
Do not use the test kit if the pouch is damaged.
In the event of a spillage, ensure that it is cleaned thoroughly using a suitable disinfectant.
Use only the components of this test kit.
Inadequate or improper sample collection may lead to inaccurate or false results.
If you suspect the presence of blood on the swab, discard the swab and repeat the test with a fresh one.
Avoid contact with skin and eyes. In case of accidental contact, rinse well in order to avoid skin irritations. In case of concerns, consult your doctor.
Keep the test kit away from children to reduce the risk of accidentally drinking the buffer liquid or swallowing small parts.
Do not use any of the test components in the body with the exception of the swab included in the kit. Do not swallow any of the components.
This test is for presumptive screening only. Please consult a doctor to discuss your test result and to ﬁnd out whether additional tests are needed. Please also consult a doctor if you have any concerns about your health, if you are experiencing prolonged symptoms, or if your symptoms are worsening.
If your test result is positive you must have a confirmatory laboratory PCR test. Consult your doctor for any follow-up clinical care.
Repeat testing is recommended (e.g. within 1-3 days) if there is an ongoing suspicion of infection, being in a high-risk setting, or where there is an occupational risk or another requirement.
Even if your test result is negative, continue to observe all applicable hygiene and safety measures. Even with a negative result, you may still be infectious. If you are showing symptoms you must seek immediate further testing by PCR.
Dispose of the kit components in your household waste (not recycling) or according to your local guidelines. The remaining liquid in the tube should not be released into the drainage system or water bodies.

Storage and stability

Store the kit at 2 ‑ 30 °C / 36 ‑ 86 °F and protect it from direct sunlight. The expiry date of the materials is indicated on the external packaging.
Do not freeze the kit.

Materials required (but not provided)

Timer
Tissue

Test preparation and sample collection

Carefully read the Instructions for Use of the SARS‑CoV‑2 Antigen Self Test Nasal. Please also see the Quick Reference Guide (with illustrations) before performing the test.

Preparing for a test

Prior to starting the procedure, the test device and reagents must be equilibrated to operating
temperature (15 ‑ 30 °C / 59 ‑ 86 °F).

Wash your hands with soap and water or use a hand sanitizer before performing the test.
Check the expiry date on the back of the foil pouches. Do not use the test if the expiry date has passed.
Open one of the foil pouches 1 by tearing along the tear‑line and take out the test device and the desiccant package. Use the test immediately after opening the pouch (if not used immediately, the test must be used within 1 hour after opening).
Ensure that the test device is intact and that there are no green beads in the desiccant package.
Do not open the desiccant package.

Collecting and preparing a nasal sample

Open foil pouch 2 by tearing along the tear‑line and taking out one of the tubes with the liquid and one nozzle cap and placing them on the table.
Open the seal of the tube carefully without spilling the liquid inside the tube. Place the tube in the tube holder.
Blow your nose once using a tissue.
Remove the swab from the packaging. Ensure that you only touch the handle of the swab and not the soft pad at the tip.
Slightly tilt your head backward.
Insert the swab with the soft pad at the front into your left nostril. Slowly slide the swab approx. 2 cm forward (parallel to the roof of your mouth – not upwards) until you encounter resistance. Do not apply any pressure.
Rotate the swab 4 times (for a total of approx. 15 seconds) against the lining of the nasal wall before removing it from the nostril.
Repeat steps 6 and 7 in your right nostril using the same swab.
Insert the swab into the tube until the soft pad is in the liquid. Squeeze the tube at the bottom and hold it tight. Stir the swab more than 10 times to transfer the biological material from the swab to the liquid.
Remove the swab while squeezing the sides of the tube to extract the liquid from the swab.
Dispose of the swab and seal the tube securely with the nozzle cap.
The same swab is used to collect samples from both nostrils.

Performing the test

Place the test device on a ﬂat surface.
Hold the tube upright above the circular well on the test device (not over the rectangular result window).
Drop exactly 4 drops onto the circular wall. Gently squeeze the sides of the tube together if necessary.
Note: You can continue with the test even if you accidentally drop 5 drops onto the test device.
Set the timer and read the test result after 15 to 30 minutes.
Wash your hands with soap and water or use a hand sanitizer after performing the test.
Failure to squeeze the tube can lead to incorrect results due to excess buffer in the swab.
Test results that are read before 15 minutes or after 30 minutes may be incorrect.

Interpreting the test results

Invalid test result:
If a control line (C) is not visible, the result must be considered invalid. The test is not working correctly and you should perform another test using a different test kit. You may have performed the test incorrectly. Carefully read the Instructions for Use and repeat the test. If your test result is still invalid, please contact your doctor or a COVID‑19 test center.
Positive test result:
If a test line (T) is visible together with a control line (C), this means that the result is positive. Look carefully at the result: The test should be considered positive if two lines are visible – even if they are faint. A positive test result means it is very likely that you have COVID‑19.
Please go directly to obtain a laboratory PCR test.

Negative test result:
If a control line (C) is visible (regardless of how faint it is) and a test line (T) is not visible, this means that the result is negative. It is unlikely that you have COVID‑19. However, even if your test is negative, continue to observe all hygiene and safety measures.
If you suspect that you have an infection (i.e., if you have prolonged symptoms or if your symptoms are worsening), contact your doctor/primary care physician. You may have another infection, or your test result may be false. You may repeat the test after 1 ‑ 2 days, as COVID‑19 cannot be detected with complete accuracy during all stages of an infection.

Limitations of the procedure

The test procedure, precautions, and interpretation of results for this test must be followed strictly when testing.
The test should be used for the detection of SARS‑CoV‑2 antigen in human nasal swab samples.
This is a qualitative test, therefore quantitative values of SARS‑CoV‑2 antigen concentration cannot be determined.
The test cannot determine if you are infectious.
The SARS‑CoV‑2 Antigen Self Test Nasal for patient self‑testing was evaluated in a study of symptomatic adults aged 18 to 68. If the test is to be used on a child or teenager under 18 years of age, the test must be performed by an adult or under adult supervision. For older individuals aged over 61, a helper should also be on hand to provide assistance with testing and result interpretation.
False-negative test results (i.e., an existing infection is not detected) may occur if testing is not performed within the first 7 days of symptom onset as the antigen level in the specimen may be too low for the test to detect.
False-negative test results may occur if the specimen was collected incorrectly.
False-negative test results may occur if the specimen swab is not mixed well in the tube (step 9 in the test procedure section).
The antigen can generally be detected using nasal swab samples during the acute phase of infection.
The test is less reliable in later phases of infections and in asymptomatic individuals.
The immune response cannot be evaluated using this test. Other test methods are required for that purpose.
Positive results indicate the presence of viral antigens. However, a clinical correlation with the case history and other diagnostic information is required to determine the status of the infection.
Positive results do not exclude the possibility that a bacterial infection or a co‑infection with another virus is present.
Human coronavirus HKU1 could not be tested in the lab. There is a very low probability of cross‑reactivity with HKU1.
False-positive results may occur in the presence of SARS‑CoV infections.
Negative results should be viewed as provisional and a PCR test should be performed as conﬁrmation if necessary.
Negative results do not rule out a SARS‑CoV‑2 infection and should not be used as the sole basis for treatment or patient management decisions, including decisions about infection control. Individuals who have tested negative and continue to show COVID‑19‑like symptoms should contact their doctor/primary care physician.

Specific performance data

Limit of detection
The limit of detection of this test is less than 150 TCID50/mL.

Clinical evaluation

The clinical performance of the SARS‑CoV‑2 Antigen Self Test Nasal for patient self‑testing was evaluated using nasal swab samples collected from 146 (of which, 139 within 7 days post symptom onset) study participants in a prospective study at a clinical center in Germany. The clinical evaluations were performed independently from the manufacturer and distributor within a collaboration between the university hospitals Charité in Berlin and Heidelberg.
The study cohort included symptomatic adults (aged 18 to 68) who were clinically suspected of having a SARS‑CoV‑2 infection.
In the patient self‑testing group, the study participants followed written instructions with illustrations for taking a nasal swab sample and performing the test themselves. The samples were collected and the tests were performed under the observation of healthcare professionals, who did not intervene at any stage. PCR tests using combined deep rose/deep throat swab samples were used as a comparative method. Nasal sampling by the self‑testers always preceded the combined deep nose/deep throat sample collection for RT‑PCR comparison. A SARS‑CoV‑2 infection was diagnosed (using PCR) in 27.4 % of the patients.

The clinical performance of the SARS‑CoV‑2 Antigen Self Test Nasal was also evaluated for professional testing following patient self‑collection and professional collection of nasal swab samples in the same clinical center. 229 adults who were clinically suspected of having a SARS‑CoV‑2 infection were included in the prospective study. 133 study participants (thereof 126 within 7 days post symptom onset) underwent nasal sampling performed by healthcare professionals and 96 study participants (thereof 83 within 7 days post symptom onset) followed instructions for collecting their nasal swab samples themselves. Self‑collection was performed under the supervision of healthcare professionals. PCR tests were performed as described above.

Test sensitivity and speciﬁcity

In the self‑testing study, the SARS‑CoV‑2 Antigen Self Test Nasal correctly identiﬁed 91.2 % (CI: 76.3 % – 98.1 %) of infected study participants with a relatively high viral load (Ct ≤ 30).
Individuals with a high viral load are considered to be at higher risk of being infected and transmitting the virus to others.
For all study participants, the antigen rapid test correctly identiﬁed 82.5 % (CI: 67.2 % – 92.7 %) of infected study participants and 100.0 % (CI: 96.5 % – 100.0 %) of non‑infected study participants.
In all 3 cohorts together, 110 PCR‑positive and 263 PCR‑negative study participants were evaluated using the SARS‑CoV‑2 Antigen Self Test Nasal. For patients with a relatively high viral load (Ct ≤ 30), the relative sensitivity was 91.1 % (95 % CI: 83.8 % ‑ 95.8 %, N=101). For all samples, the overall relative sensitivity and the overall relative specificity were 86.4 % (95 % CI: 78.5 % ‑ 92.2 %) and 99.6 % (95 % CI: 97.9 % ‑ 100.0 %), respectively.
For patients tested within 7 days post symptom onset (DPSO), the relative sensitivity was 87.4 % (95 % CI: 79.4 % ‑ 93.1 %) and the relative speciﬁcity was 99.6 % (95 % CI: 97.7 % ‑ 100.0 %).

One sample was excluded from the analysis because the PCR test result was not available.
One sample (PCR negative) was excluded from the analysis because the antigen test result was not available.
Ct values are commonly used to estimate the amount of the viral material in samples. A low Ct value suggests the presence of a lot of viral material, and a high Ct value suggests the presence of lower levels of viral material.
