SPECIMEN COLLECTION

Self-collected the nasal swab samples by individuals aged 14

years or older. Or adult collect nasal swab samples from

individuals aged 2 years or older. Children aged 13 years old

and younger should be tested by a parent or legal guardian.

TEST PROCEDURE

 

Wash or sanitize your hands and

keep them dry before testing.

 

 

 

Peel off the aluminum foil on the

extraction buffer tube.

 

 

 

Place the extraction

buffer tube in the tube

holder on the kit box.

 

Remove nasal swab

from its packaging.

Prepare to collect sample. 

If collecting from a child, 

you may need another 

 y h h ’ 

head while swabbing.

 

 

Gently insert swab 1⁄2 - 3⁄4 

inch into first nostril, or 

until you feel resistance.

Slowly make at least 5 

rotations with the swab 

firmly against the walls 

of the nostril for 

approximately 15 seconds.

 

 

Repeat step #6 in your 

second nostril using 

the same swab.

 

 

Take the tube out of the tube holder.

Place the swab into the tube, ensure

the swab tip is in the liquid inside

the tube.

Stir the swab tip against the bottom

and side of the tube for at least 15

times.

 

 

 

Squeeze the swab tip at least

5 times from outside of the

tube while the swab tip remains

in the liquid.

 

 

 

 

While squeezing the sides of

the vial firmly, pull the swab

out to remove excess liquid.

Dispose of the swab in provided

disposal bag.

 

Firmly press the dropper tip on

Results should be considered in the context of an v ’ recent exposures, history,

and the presence of clinical signs and symptoms consistent with COVID-19.

COVID-19 Positive (+)

If the Control (C) line and the Test (T) line are visible, the test is

positive. Any faint visible red/purple test (T) line with the control

line (C) should be read as positive.

You do not need to perform repeat testing if you have a positive result at any time.

A positive test result means that the virus that causes COVID-19 was detected in your

sample and it is very likely you have COVID-19 and are contagious. Please contact your

doctor/primary care physician or your local health authority immediately and adhere to

the local guidelines regarding self-isolation. There is a very small chance that this test can

give a positive result that is incorrect (a false positive).

Individuals who test positive with the Advin COVID-19 Antigen Test @Home should selfisolate and seek follow up care with their physician or healthcare provider.

COVID-19 Negative (-)

If the Control (C) line is visible, but the Test (T) line is not visible, the test is

negative.

To increase the chance that the negative result for COVID-19 is accurate,

you should:

·Test again in 48 hours if you have symptoms on the first day of testing.

·Test 2 more times at least 48 hours apart if you do not have symptoms on the first day

of testing.

A negative test result indicates that the virus that causes COVID-19 was not detected in

your sample. A negative result is presumptive, meaning it is not certain that you do not

have COVID-19. You may still have COVID-19 and you may still be contagious. There is a

higher chance of false negative results with antigen tests compared to laboratory-based

tests such as PCR. If you test negative and continue to experience COVID-19-like

symptoms, (e.g., fever, cough, and/or shortness of breath) you should seek follow up care

with your health care provider.

All negative results should be treated as presumptive and confirmation with a molecular

assay may be necessary if there is a high likelihood of SARS-CoV-2 infection, such as in an

individual with a close contact with COVID-19 or with suspected exposure to COVID-19 or

in communities with high prevalence of infection. Negative results do not rule out SARSCoV-2 infection and should not be used as the sole basis for treatment or patient

management decisions, including infection control decisions.

Invalid

If the control (C) line is not visible, the test is invalid. Re-test with a new

swab and new test device. Insufficient specimen volume or incorrect

procedural techniques are the most likely reasons for control line failure.

Review the procedure and repeat the test with a new test. If the

problem persists, discontinue using the test kit immediately and contact

your local distributor or manufacturer for technical support.

 Intended Use 

The Advin COVID-19 Antigen Test @ Home is a lateral flow immunoassay device intended for the 

qualitative detection of nucleocapsid protein antigens from SARS-CoV-2. 

This test is authorized for non-prescription home use with self-collected anterior nasal (nares) swab 

samples from individuals aged 14 years or older or with adult-collected anterior nasal (nares) 

samples from individuals aged 2 years or older. This test is authorized for individuals with symptoms 

of COVID-19 within the first 7 days of symptom onset when tested at least twice over three days 

with at least 48 hours between tests, and for individuals without symptoms or other 

epidemiological reasons to suspect COVID-19, when tested at least three times over five days with 

at least 48 hours between tests. 

The Advin COVID-19 Antigen Test @ Home does not differentiate between SARS-CoV and SARSCoV-2.

Results are for the identification of SARS-CoV-2 nucleocapsid protein antigen, which is generally 

detectable in anterior nasal (nares) swab samples during the acute phase of infection. Positive 

results indicate the presence of viral antigens, but clinical correlation with past medical history and 

other diagnostic information is necessary to determine infection status. Positive results do not rule 

out bacterial infection or co-infection with other viruses and the agent detected may not be the 

definite cause of disease. Individuals who test positive with the Advin COVID-19 Antigen Test @ 

Home should self-isolate and seek follow-up care with their physician or healthcare provider as 

additional testing may be necessary. 

All negative results are presumptive and confirmation with a molecular assay, if necessary for 

patient management, may be performed. Negative results do not rule out SARS-CoV-2 infection 

and should not be used as the sole basis for treatment or patient management decisions, including 

infection control measures such as isolating from others and wearing masks. Negative result should 

be considered in the context of an individual’s recent exposures, history, and the presence of clinical 

signs and symptoms consistent with COVID-19. 

Individuals who test negative and continue to experience COVID-19 like symptoms of fever, cough 

and/or shortness of breath may still have SARS-CoV-2 infection and should seek follow up care with 

their physician or healthcare provider. 

Individuals should provide all results obtained with this product to their healthcare provider for 

public health reporting and to receive appropriate medical care. All healthcare providers will report 

all test results they receive from individuals who use the authorized product to relevant public 

health authorities in accordance with local, state, and federal requirements using appropriate 

LOINC and SNOMED codes, as defined by the Laboratory In Vitro Diagnostics (LIVD) Test Code 

Mapping for SARS-CoV-2 Tests provided by the CDC. 

The Advin COVID-19 Antigen Test @ Home is intended for non-prescription self-use and/or, as 

applicable for an adult lay user testing another person aged 2 years or older in a non-laboratory 

setting. 

The Advin COVID-19 Antigen Test @ Home is only for use under the Food and Drug Administration’s 

Emergency Use Authorization. This product has not been FDA cleared or approved.

 How to Use This Test 

Serial testing should be performed in all individuals with negative results; individuals with 

symptoms of COVID-19 and initial negative results should be tested again after 48 hours. Individuals 

without symptoms of COVID-19, and with initial negative results, should be tested again after 48 

hours and, if the 2nd test is also negative, a 3rd time after an additional 48 hours. You may need to 

purchase additional tests to perform this serial (repeat) testing.

If you test negative but continue to have symptoms of COVID-19, and both your first and second 

tests are negative, you may not have COVID-19, however you should follow-up with your healthcare 

provider. 

If your test is positive, then proteins from the virus that causes COVID-19 have been found in your 

sample and you likely have COVID-19.

 Warning, Precautions and Safety Information 

• Read all instructions carefully before performing the test. Failure to follow the instructions 

may result in inaccurate test results.

• In the USA, this product has not been FDA cleared or approved, but has been authorized by 

FDA under an Emergency Use Authorization. This product has been authorized only for the 

detection of proteins from SARS-CoV-2, not for any other viruses or pathogens. The emergency 

use of this product is only authorized for the duration of the declaration that circumstances

 Limitations 

• There is a higher chance of false negative results with antigen tests than with laboratory-based 

molecular tests due to the sensitivity of the test technology. This means that there is a higher 

chance this test will give a false negative result in an individual with COVID-19 as compared to 

a molecular test, especially in samples with low viral load.

• The performance of this test was established based on the evaluation of a limited number of 

clinical specimens collected between April 2022 to May 2022. The clinical performance has 

not been established for all circulating variants but is anticipated to be reflective of the 

prevalent variants in circulation at the time and location of the clinical evaluation. 

Performance at the time of testing may vary depending on the variants circulating, including 

newly emerging strains of SARS-CoV-2 and their prevalence, which change over time.

• All COVID-19 antigen test negative results are presumptive and confirmation with a molecular 

assay may be necessary. If you continue to have symptoms of COVID-19, and both your first 

and second tests are negative, you may not have COVID-19, however you should follow-up 

with a healthcare provider. 

• If the test is positive, then proteins from the virus that causes COVID-19 have been found in 

the sample and you likely have COVID-19.

• This test is read visually and has not been validated for use by those with impaired vision or 

color-impaired vision.

• Incorrect test results may occur if a specimen is incorrectly collected or handled.

WHAT IS THE DIFFERENCE BETWEEN AN ANTIGEN AND MOLECULAR TEST?

There are different kinds of tests for the SARS-CoV-2 virus that causes COVID-19. Molecular tests 

detect genetic material from the virus. Antigen tests, such as the Advin COVID-19 Antigen Test 

@Home, detect proteins from the virus. Due to the lower sensitivity of antigen tests, there is a 

higher chance this test will give you a false negative result when you have COVID-19 than a 

molecular test would.

HOW ACCURATE IS THIS TEST?

Clinical studies have shown that antigen tests more accurately determine whether you are infected 

with the virus that causes COVID-19 when taken multiple times across several days. Repeat testing 

improves test accuracy. This serial testing approach is recommended to minimize the risk of 

incorrect results. For more information on the performance of the test and how the performance 

may apply to you, please refer to the performance data in the Healthcare Provider Instructions for 

Use (IFU), available at http://www.advinbio.com.

WHAT IF I HAVE A POSITIVE TEST RESULT?

A positive result means that it is very likely you have COVID-19 because proteins from the virus that 

causes COVID-19 were found in your sample. You should self-isolate from others and contact a 

healthcare provider for medical advice about your positive result.

WHAT IF I HAVE A NEGATIVE TEST RESULT?

A negative test result indicates that antigens from the virus that causes COVID-19 were not 

detected in your sample. However, if you have symptoms of COVID-19, and your first test is negative, 

you should test again in 48 hours since antigen tests are not as sensitive as molecular tests. If you 

do not have symptoms and received a negative result, you should test at least two more times with 

48 hours in between tests for a total of three tests. If you have a negative result, it does not rule 

out SARS-CoV-2 infection; you may still be infected and you may still infect others. It is important 

that you work with your healthcare provider to help you understand the next steps you should take.

WHAT DOES AN INVALID TEST RESULT MEAN?

An invalid result means the test was not able to tell if you have COVID-19 or not. If the test is invalid, 

a new swab should be used to collect a new nasal specimen and you should test again with a new 

test.

IMPORTANT 

Do not use this test as the only guide to manage your illness. Consult your healthcare provider if 

your symptoms persist or become more severe.

Individuals should provide all results obtained with this product to their healthcare provider.
