Part 1 – Sample Test Procedure

Patient Samples require 6 drops of Extraction Reagent

1. Correct

Hold Extraction Reagent bottle vertically. Hovering 1/2
inch above the TOP HOLE, slowly add 6 DROPS to the             TOP HOLE of the swab well. DO NOT touch the card
with the dropper tip while dispensing.

2.

Insert sample or control swab into BOTTOM HOLE and
firmly push upwards so that the swab tip is visible in the
TOP HOLE.

Rotate (twirl) swab shaft 3 times CLOCKWISE (to
the right). Do not remove swab.

Used test cards should be discarded as Biohazard waste according to Federal, State and local regulatory requirements.

Peel off adhesive liner from the right edge of the test card.
Close and securely seal the card. Read result in the window
15 minutes after closing the hard. In order to ensure proper
test performance, it is important to read the result promptly at 15 minutes, and not before. Results should not be read after 30 minutes.

complexity tests. This test is authorized for use at the Point of Care (POC), i.e., in patient care settings operating under a CLIA Certifcate of Waiver, Certifcate of Compliance, or Certifcate of Accreditation. This product has been authorized only for the detection of proteins from SARS-CoV-2, not for any other viruses or pathogens. In the USA, – this product is only authorized for the duration of the declaration that circumstances exist justifying the authorization of emergency use of in vitro diagnostics for detection and/or diagnosis of the virus that causes COVID-19 under Section 564(b)(1) of the Federal Food, Drug and Cosmetic Act, 21 U.S.C. § 360bbb-3(b)(1), unless the authorization is terminated or revoked
sooner.

Part 2 – Result Interpretation

Negative Result

A negative specimen will give a single pink/purple colored Control
Line in the top half of the window, indicating a negative result. This Control Line means that the detection part of the test was done correctly, but no COVID-19 antigen was detected. Negative results should be treated as presumptive and confirmation with a molecular
assay, if necessary, for patient management, may be performed.

Positive Result

A positive specimen will give two pink/purple colored lines.
This means that COVID-19 antigen was detected. Specimens
with low levels of antigen may give a faint Sample Line. Any visible pink/purple colored line is positive.

Invalid Result

If no lines are seen, or if just the Sample Line is seen, the assay is
invalid. Invalid tests should be repeated.

Procedure for External Quality Control Testing

External Controls require 8 drops of Extraction Reagent Hold

1. Extraction Reagent bottle vertically. Hovering 1/2 inch
   above the TOP HOLE, slowly add 8 DROPS to the TOP HOLE of the swab well. DO NOT touch the card with the dropper tip while dispensing.

2. Follow Steps 2 – 4 of the Test Procedure shown.

INTENDED USE
The BinaxNOWTM COVID-19 Ag Card is a lateral flow immunoassay intended for the qualitative detection of nucleocapsid protein antigen from SARS-CoV-2 in direct anterior nasal (nares) swabs from individuals suspected of COVID-19 by their healthcare provider within the first seven days of symptom onset. Testing is limited to laboratories certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA), 42 U.S.C. §263a, that meet the requirements to perform moderate, high or waived complexity tests. This test is authorized for use at the Point of
Care (POC), i.e., in patient care settings operating under a CLIA Certificate of Waiver, Certificate of Compliance, or Certificate of Accreditation.
The BinaxNOWTM COVID-19 Ag Card does not differentiate between SARS-CoV and SARS-CoV-2.
Results are for the identification of SARS-CoV-2 nucleocapsid protein antigen. Antigen is generally detectable in anterior nasal (nares) swabs during the acute phase of infection. Positive
results indicate the presence of viral antigens, but clinical correlation with patient 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. The agent detected may not be the definite cause of disease. Laboratories within the United States and its territories are required to report all results to the appropriate public health authorities.
Negative results should be treated as presumptive and confirmation with a molecular assay, if necessary, for patient management, may be performed. 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. Negative results should be considered in the
context of a patient’s recent exposures, history and the presence of clinical signs and symptoms consistent with COVID-19.
The BinaxNOWTM COVID-19 Ag Card is intended for use by medical professionals or trained operators who are proficient in performing rapid lateral flow tests. BinaxNOWTM COVID-19 Ag
Card is only for use under the Food and Drug Administration’s Emergency Use Authorization.

SUMMARY AND EXPLANATION OF THE TEST

Coronaviruses are a large family of viruses which may cause illness in animals or humans. SARSCoV-2 is an enveloped, single-stranded RNA virus of the β genus. The virus can cause mild to

severe respiratory illness and has spread globally, including the United States.
BinaxNOWTM COVID-19 Ag Card is a rapid lateral flow immunoassay for the qualitative detection and diagnosis of SARS-CoV-2 directly from nasal swabs, without viral transport media. The BinaxNOWTM COVID-19 Ag Card kit contains all components required to carry out an assay for SARS-CoV-2.

PRINCIPLES OF THE PROCEDURE

The BinaxNOWTM COVID-19 Ag Card is an immunochromatographic membrane assay that uses
highly sensitive antibodies to detect SARS-CoV-2 nucleocapsid protein from nasal swab specimens. SARS-CoV-2 specific antibodies and a control antibody are immobilized onto a
membrane support as two distinct lines and combined with other reagents/pads to construct a test strip. This test strip and a well to hold the swab specimen are mounted on opposite sides of
a cardboard, book-shaped hinged test card. To perform the test, a nasal swab specimen is collected from the patient, 6 drops of extraction reagent from a dropper bottle are added to the top hole of the swab well. The patient sample is inserted into the test card through the bottom hole of the swab well, and firmly pushed upwards until the swab tip is visible through the top hole. The swab is rotated 3 times clockwise and the card is closed, bringing the extracted sample into contact with the test strip. Test results are
interpreted visually at 15 minutes based on the presence or absence of visually detectable pink/purple colored lines. Results should not be read after 30 minutes.

STORAGE AND STABILITY

Store kit at 2-30°C. The BinaxNOWTM COVID-19 Ag Card kit is stable until the expiration date marked on the outer packaging and containers. Ensure all test components are at room temperature before use.

QUALITY CONTROL

BinaxNOWTM COVID-19 Ag Card has built-in procedural controls. For daily quality control, Abbott suggests that you record these controls for each test run.

Procedural Controls:

1. The pink-to-purple line at the “Control” position is an internal procedural control. If the test flows and the reagents work, this line will always appear.
2. The clearing of background color from the result window is a negative background control. The background color in the window should be light pink to white within 15 minutes. Background color should not hinder reading of the test.

External Positive and Negative Controls:
Good laboratory practice suggests the use of positive and negative controls to ensure that test reagents are working and that the test is correctly performed. BinaxNOWTM COVID-19 Ag Card
kits contain a Positive Control Swab and Sterile Swabs that can be used as a Negative Control Swab. These swabs will monitor the entire assay. Test these swabs once with each new shipment
received and once for each untrained operator. Further controls may be tested in order to conform with local, state and/or federal regulations, accrediting groups, or your lab’s standard Quality
Control procedures.

If the correct control results are not obtained, do not perform patient tests or report patient results. Contact Technical Support during normal business hours before testing patient specimens.

SPECIMEN COLLECTION AND HANDLING

Test specimens immediately after collection for optimal test performance. Inadequate specimen collection or improper sample handling/storage/transport may yield erroneous results. Refer to
the CDC Interim Guidelines for Collecting, Handling, and Testing Clinical Specimens from Persons for Coronavirus Disease 2019 (COVID-19) https://www.cdc.gov/coronavirus/2019 nCoV/lab/guidelines-clinical- specimens.html

Anterior Nasal (Nares) Swab
Only the swab provided in the kit is to be used for nasal swab collection.
To collect a nasal swab sample, carefully insert the entire absorbent tip of the swab (usually ½ to ¾ of an inch (1 to 1.5 cm) into the nostril. Firmly sample the nasal wall by rotating the swab in a circular path against the nasal wall 5 times or more for a total of
15 seconds, then slowly remove from the nostril. Using the same swab, repeat sample collection in the other nostril.

SPECIMEN TRANSPORT AND STORAGE

Do not return the nasal swab to the original paper packaging.
For best performance, direct nasal swabs should be tested as soon as possible after collection. If immediate testing is not possible, and to maintain best performance and avoid possible contamination, it is highly recommended the nasal swab is placed in a clean, unused plastic tube labeled with patient information, preserving sample integrity, and capped tightly at room temperature (15-30°C) for up to (1) hour prior to testing. Ensure the swab fits securely within the tube and the cap is tightly closed. If greater than 1 hour delay occurs, dispose of sample. A new sample must be collected for testing.

TEST PROCEDURE

Procedure for Patient Specimens

Open the test card just prior to use, lay it flat, and perform assay as follows. The test card must be flat when performing testing, do not perform testing with the test card in any other position.

1. Hold Extraction Reagent bottle vertically. Hovering 1/2 inch above the TOP HOLE, slowly add 6 DROPS to the TOP HOLE of the swab well. DO NOT touch the card with the dropper tip while dispensing.
   

2. Insert sample into BOTTOM HOLE and firmly push upwards so that the swab tip is visible in the TOP HOLE.
   
   

3. Rotate (twirl) swab shaft 3 times CLOCKWISE (to the right). Do not remove swab.

Note: False negative results can occur if the sample swab is not rotated (twirled) prior to closing the card.

4. Peel off adhesive liner from the right edge of the test card. Close and securely seal the card. Read result in the window 15 minutes after closing the card. In order to ensure proper test performance, it is important to read the result promptly at 15 minutes, and not before. Results should not be read after 30 minutes.

Note: False negative results can occur if test results are read before 15 minutes.
Note : When reading test results, tilt the card to reduce glare on the result window if necessary. Individuals with color-impaired vision may not be able to adequately interpret test results.

Procedure for BinaxNOW™ Swab Controls

Open the test card just prior to use, lay it flat, and perform assay as follows.

1. Hold Extraction Reagent bottle vertically Hovering 1/2 inch above the TOP HOLE , slowly add 8 DROPS to the TOP HOLE of the swab well. DO NOT touch the card with the dropper tip while dispensing.
   

2. Follow Steps 2 – 4 of the Test Procedure for Patient Specimens.

RESULT INTERPRETATION

Note: In an untested BinaxNOW COVID-19 Ag Card there will be a blue line present at the Control Line position. In a valid, tested device, the blue line washes away and a pink/purple line appears, confirming that the sample has flowed through the test strip and the reagents are working. If the blue line is not present at the Control Line position prior to running the test, do not use and discard the test card.

Negative

A negative specimen will give a single pink/purple
colored Control Line in the top half of the window, indicating a negative result. This Control Line means that the detection part of the test was done correctly, but no COVID-19 antigen was detected.

Positive

A positive specimen will give two pink/purple colored lines. This means that COVID-19 antigen was detected. Specimens with low levels of antigen may give a faint Sample Line. Any visible pink/purple colored line is positive.

Invalid

If no lines are seen, if just the Sample Line is seen, or the Blue Control Line remains blue, the assay is invalid. Invalid tests should be repeated.

LIMITATIONS

• This test detects both viable (live) and non-viable, SARS-CoV, and SARS-CoV-2. Test performance depends on the amount of virus (antigen) in the sample and may or may not correlate with viral culture results performed on the same sample.

• A negative test result may occur if the level of antigen in a sample is below the detection limit of the test.

• The performance of the BinaxNOW™ COVID-19 Ag Card was evaluated using the procedures provided in this product insert only. Modifications to these procedures may alter the
  performance of the test.

• False negative results may occur if a specimen is improperly collected, transported, or handled.

• False results may occur if specimens are tested past 1 hour of collection. Specimens should be test as quickly as possible after specimen collection.

• False negative results may occur if inadequate extraction buffer is used (e.g., <6 drops).

• False negative results may occur if specimen swabs are not twirled within the test card.

• False negative results may occur if swabs are stored in their paper sheath after specimen collection.

• Positive test results do not rule out co-infections with other pathogens.

• False negative results are more likely after eight days or more of symptoms.

• Positive test results do not differentiate between SARS-CoV and SARS-CoV-2.

• Negative test results are not intended to rule in other non-SARS viral or bacterial infections.

• The presence of mupirocin may interfere with the BinaxNOW™ COVID-19 Ag test and may cause false negative results.

• Negative results should be treated as presumptive and confirmation with a molecular assay, if necessary, for patient management, may be performed.

• If the differentiation of specific SARS viruses and strains is needed, additional testing, in consultation with state or local public health departments, is required.

PERFORMANCE CHARACTERISTICS

CLINICAL PERFORMANCE

Clinical performance characteristics of BinaxNOW™ COVID-19 Ag Card was evaluated in a multisite prospective study in the U.S in which patients were sequentially enrolled and tested. A total
of ten (10) investigational sites throughout the U.S. participated in the study. Testing was performed by operators with no laboratory experience and who are representative of the intended users at CLIA waived testing sites. In this study testing was conducted by sixty-two (62) intended users. To be enrolled in the study, patients had to be presenting at the participating study centers with suspected COVID-19. Patients who presented within 7 days of symptom onset were included in the initial primary analysis. Two nasal swabs were collected from patients and tested using the
BinaxNOW™ COVID-19 Ag Card at all study sites. An FDA Emergency Use Authorized real-time Polymerase Chain Reaction (RT-PCR) assay for the detection of SARS- CoV-2 was utilized as the comparator method for this study. At all sites, one nasal swab was tested directly in the BinaxNOW™ COVID-19 Ag Card test according to product instructions and the other swab was eluted in viral transport media (VTM). Swabs were randomly assigned to testing with the BinaxNOW or RT-PCR testing and were tested
by minimally trained operators who were blinded to the RT-PCR test result. All sites shipped the VTM sample to a central testing laboratory for RT-PCR.
External control testing, using BinaxNOW™ COVID-19 Ag Card Positive and Negative Controls,
was performed prior to sample testing each day, at all study sites.
The performance of BinaxNOW™ COVID-19 Ag Card was established with 460 nasal swabs collected from individual symptomatic patients (within 7 days of onset) who were suspected of COVID-19.

*In patients presenting within seven (7) days of symptom onset, BinaxNOW COVID-19 Ag Card achieved 95.6% (86/90) positive percent agreement for samples with Ct < 33

Patient Demographics

Patient demographics (gender and age) are available for the 460 samples used in the analysis of patients with symptom onset within the previous seven (7) days. The table below shows the positive results broken down by age of the patient:

Patient demographics, time elapsed since onset of symptoms for all patients enrolled, are presented in the table below. Positive results broken down by days since symptom onset:

A cohort of patients who presented with symptom onset greater than seven days were enrolled in the clinical study (n = 161). The positive agreement in patients with symptoms greater than seven
days was 60% (30/50) and negative agreement was 98% (109/111). Therefore, negative results in patients with symptom onset greater than seven days should be interpreted with caution, as the sensitivity of the assay decreases over time.

ANALYTICAL PERFORMANCE

Limit of Detection (Analytical Sensitivity)

BinaxNOW™ COVID-19 Ag Card limit of detection (LOD) was determined by evaluating different concentrations of heat inactivated SARS-CoV-2 virus. Presumed negative natural nasal swab specimens were eluted in PBS. Swab eluates were combined and mixed thoroughly to create a clinical matrix pool to be used as the diluent. Inactivated SARS-CoV-2 virus was diluted in this
natural nasal swab matrix pool to generate virus dilutions for testing.
Contrived nasal swab samples were prepared by absorbing 20 microliters of each virus dilution onto the swab. The contrived swab samples were tested according to the test procedure.
The LOD was determined as the lowest virus concentration that was detected ≥ 95% of the time (i.e., concentration at which at least 19 out of 20 replicates tested positive).
The BinaxNOW™ COVID-19 Ag Card LOD in natural nasal swab matrix was confirmed as 140.6 TCID50/mL.

Limit of Detection (LoD) Study Results

Cross Reactivity (Analytical Specificity) and Microbial Interference

Cross reactivity and potential interference of BinaxNOW™ COVID-19 Ag Card was evaluated by testing 37 commensal and pathogenic microorganisms (8 bacteria, 14 viruses, 1 yeast and pooled human nasal wash) that may be present in the nasal cavity. Each of the organism, viruses, and yeast were tested in triplicate in the absence or presence of heat inactivated SARS-CoV-2 virus
(45 TCID50/swab). No cross-reactivity or interference was seen with the following microorganisms when tested at the concentration presented in the table below.

To estimate the likelihood of cross-reactivity with SARS-CoV-2 virus in the presence of organisms that were not available for wet testing, In silico analysis using the Basic Local Alignment Search
Tool (BLAST) managed by the National Center for Biotechnology  information (NCBI) was used to assess the degree of protein sequence homology.

• For P. jirovecii one area of sequence similarity shows 45% homology across 18% of the sequence, making cross-reactivity in the BinaxNOW™ COVID-19 Ag Card highly unlikely.
• No protein sequence homology was found between M. tuberculosis, and thus homologybased cross-reactivity can be ruled out.
• The comparison between SARS-CoV-2 nucleocapsid protein, MERS-CoV and human coronavirus HKU1 revealed that cross-reactivity cannot be ruled out. Homology for KHU1 and MERS-CoV is relatively low, at 37.8% across 95% of the sequence and 57.14% across 87% of the sequence, respectively

High Dose Hook Effect

No high dose hook effect was observed when tested with up to a concentration of 1.6 x 105 TCID50/mL of heat inactivated SARS-CoV-2 virus with the BinaxNOW™ COVID-19 Ag Card.

Endogenous Interfering Substances

The following substances, naturally present in respiratory specimens or that may be artificially introduced into the nasal cavity or nasopharynx, were evaluated with the BinaxNOW™ COVID19 Ag Card at the concentrations listed below and were found not to affect test performance.

1-Testing demonstrated false negative results at concentrations of 5 mg/mL (0.5% w/v). Standard dose of nasal ointment: 20 mg (2% w/w) of mupirocin in single-use 1-gram tubes.

FAQS

Abbott, not customers: what is the difference between this antigen self test and the binaxnow covid-19 ag card home test?

The BinaxNOW COVID-19 Antigen Self Test does not currently pair with the NAVICA app. The BinaxNOW COVID-19 Home Test can provide a sharable digital COVID-19 result, through collaboration with eMed. The BinaxNOW COVID-19 Antigen Self Test is the identical test card to the professional test but can be purchased at retail locations without a prescription. There’s also no need for a healthcare professional or online proctor to administer the swab or interpret results. Please let us know if there is anything else we can help you with.

Waiting for customer reviews. How accurate is the test?

This is an antigen test, not as accurate as a PCR molecular test. Depends on the viral load in your nasal passages. If positive you are likely infected with Covid. If negative and have symptoms test again and get a PCR test.

Can I use the BinaxNOW COVID-19 Ag Card for testing nasal swabs from contacts of confirmed SARS patients?

No. The BinaxNOW COVID-19 Ag Card is for testing only patients who are suspected of having SARS by their healthcare provider.

Can I use the BinaxNOW COVID-19 Ag Card to test nasal swabs from contacts of suspected SARS patients?

Yes. The BinaxNOW COVID-19 Ag Card is for testing nasal swabs from contacts of suspected SARS patients.

What if I have a negative result on the BinaxNOW COVID-19 Ag Card and my patient is still sick?

If your patient has a negative result on the BinaxNOW COVID-19 Ag Card and remains ill, contact your local or state health department immediately.

What if I have a positive result on the BinaxNOW COVID-19 Ag Card and my patient is not sick?

If your patient has a positive result on the BinaxNOW COVID-19 Ag Card and is not sick, contact your local or state health department immediately.

What if I have a positive result on the BinaxNOW COVID-19 Ag Card and my patient is not available for further testing?

If your patient has a positive result on the BinaxNOW COVID-19 Ag Card and is not available for further testing, contact your local or state health department immediately.

How long can I store the sample after collection before testing?

The sample must be tested as soon as possible after collection. Do not store samples longer than 24 hours at 2 to 8 degrees Celsius (36 to 46 degrees Fahrenheit). Do not freeze samples. After 24 hours, samples should be discarded.

What specific variants can this detect~ What variants were used in the efficacy test specimens? Are these specified in the package/materials?

Abbott is intently monitoring the mutations of COVID so we can ensure our tests can detect them, as we do with many viruses. We have conducted a thorough analysis of known variants that we’ve been able to study, and we are confident that our tests remain effective at identifying these strains. It is highly likely that future COVID-19 strains will remain detectable because our tests – and most other COVID-19 tests – look for parts of the virus that are crucial for the virus’ survival and therefore less subject to mutation. Please feel free to call 1-833-637-1594 if you need further assistance.

does it test for antibodies?

No, this is an antigen test that only detects an active infection. Antibody tests can detect past infections. Please let us know if there is anything else we can help you with.

What are the specificity and sensitivity ratings for this test?

Based on the interim results of a clinical study where the BinaxNOW™ COVID-19 Antigen Self Test was compared to an FDA authorized high sensitivity SARS- CoV-2 test, BinaxNOW COVID-19 Antigen Self Test correctly identified 84.6% of positive specimens and 98.5% of negative specimens.

False positive and false negative rates for the test?

Based on the interim results of a clinical study where the BinaxNOW™ COVID-19 Antigen Self Test was compared to an FDA authorized high sensitivity SARS- CoV-2 test, BinaxNOW COVID-19 Antigen Self Test correctly identified 84.6% of positive specimens and 98.5% of negative specimens.

Is this item hsa/fsa eligible?

That’s up to individual insurance companies to determine. Some cover other Over-the-Counter products so individuals would need to reach out to their provider to determine coverage.

Why did Abbott stop making this test?
