BD Veritor™ At-Home COVID-19 Test

INTENDED USE

The BD Veritor™ At-Home COVID-19 Test is a chromatographic, digital immunoassay intended for the qualitative detection of nucleocapsid protein antigen from SARS-CoV-2. The test results are interpreted by the Scanwell® Health App and displayed on a compatible smartphone.

This test is authorized for non-prescription home use with self-collected anterior nasal swab samples from individuals aged 14 years or older with symptoms of COVID-19 within the first 7 days of symptom onset. This test is also authorized for non-prescription home use with adult-collected anterior nasal swab samples from individuals aged 2 years or older, with symptoms of COVID-19 within the first 7 days of symptom onset.

This test is also authorized for non-prescription home use with self-collected anterior nasal swab samples from individuals aged 14 years or older, or with adult-collected anterior nasal swab samples from individuals aged 2 years or older, with or without symptoms or other epidemiological reasons to suspect COVID-19 when tested twice over three days with at least 24 hours (and no more than 48 hours) between tests.

The BD Veritor™ At-Home COVID-19 Test 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 swabs 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. The agent detected may not be the definite cause of disease. Individuals who test positive with the BD Veritor™ At-Home COVID-19 Test should self-isolate and seek follow-up care with their physician or healthcare provider as additional testing may be necessary.

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 SARS-CoV-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 an individual's recent exposures, history and the presence of clinical signs and symptoms consistent with COVID-19.

For serial testing programs, additional confirmatory testing with a molecular test for negative results may be necessary, if there is a high likelihood of COVID-19, such as, an individual with a close contact with COVID-19 or with suspected exposure to COVID-19 and/or in communities with high prevalence of infection. Additional confirmatory testing with a molecular test for positive results may also be necessary if there is a low likelihood of COVID-19 such as in individuals without known exposures to COVID-19 or residing in communities with low prevalence of infection.

Individuals who test negative and continue to experience COVID-like symptoms of fever, cough and/or shortness of breath may still have SARS-CoV-2 infection and should seek follow up care from their healthcare provider.

Test results are reported 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. Test result reporting from the BD Veritor™ At-Home COVID-19 Test occurs via the Scanwell Health App software application. Individuals should also report their test result to their healthcare provider to receive appropriate medical care.

The BD Veritor™ At-Home COVID-19 Test is intended for non-prescription self-use and/or, as applicable for an adult lay user testing another person aged 2 years or older. The BD Veritor™ At-Home COVID-19 Test is only for use under the Food and Drug Administration's Emergency Use Authorization.

SUMMARY AND EXPLANATION OF THE TEST

A novel coronavirus (2019-nCoV) was identified in December 2019, which has resulted in hundreds of thousands of confirmed human infections worldwide. Cases of severe illness and deaths have been reported. On February 11, 2020, the International Committee for Taxonomy of Viruses (ICTV) renamed the virus SARS-CoV-2.

The median incubation time is estimated to be approximately 5 days with symptoms estimated to be present within 12 days of infection. The symptoms of COVID-19 are similar to other viral respiratory diseases and include fever, cough, and shortness of breath.

The BD Veritor™ At-Home COVID-19 Test is a system consisting of a rapid (approximately 15 minutes) single-use chromatographic immunoassay with results interpreted by the Scanwell Health App and displayed on a compatible smartphone. The BD Veritor™ At-Home COVID-19 Test is used for the direct and qualitative detection of the presence or absence of SARS-CoV-2 nucleocapsid antigens in anterior nasal (nares) specimens, taken from individuals symptomatic for COVID-19. It is also for use in individuals without symptoms when used in a serial testing program as described in the authorized intended use. The test is intended for non-prescription, home use with self-collected (14 years or older) or adult-collected (from 2 years or older) anterior nasal swabs.

PRINCIPLES OF THE PROCEDURE

The BD Veritor™ At-Home COVID-19 Test system consists of an immunochromatographic assay and smartphone app intended to detect the presence or absence of SARS-CoV-2 nucleocapsid antigens in anterior nasal specimens from individuals symptomatic for COVID-19 or for use in individuals without symptoms when used in a serial testing program. When a nasal specimen is added to the Tube containing extraction fluid and the extracted specimen is then added to the Test Stick, SARS-CoV-2 nucleocapsid antigens present in the specimen bind to antibodies conjugated to detector particles in the test strip. The antigen-conjugate complexes migrate across the test strip to the test reaction area and are captured by a line of antibodies bound to the membrane. The Test Sticks are designed with spatially distinct reaction zones which include distinct positive and negative control line positions, a sample adequacy line position and the test line position for SARS-CoV-2. The positive and negative control lines are internal reagent controls designed to assure the Test Stick reagents are viable and that the test has been properly conducted. The sample adequacy line is designed to detect an endogenous biomarker, to assure human specimen is present. Interpretation and reporting of the correct test result, from the multiple lines deposited in the reaction zone, requires the use of the Scanwell Health App to process a scanned image of the Test Stick.

TEST PROCEDURE AND RESULTS INTERPRETATION

When opening of the BD Veritor™ At-Home COVID-19 Test kit, the user is instructed to first read the Quick Start Guide (QSG), download and open the Scanwell Health App from their app store, create or login to their Scanwell Account, and follow the step-by-step instructions provided in the app.

The app guides the user through the test, using audio as well as written and video instructions. The test procedure includes five main sections, outlined below.

1. Test Preparation

• The user is guided through a home lighting test using the Scan Card.
• Upon successful completion of the home lighting test, the user is instructed to wash their hands before proceeding to the next step.
• The user is instructed to take the components required for a single test out of the test kit box and arrange them on a clean, well-lit working surface.
• Instructions are provided for the preparation of the Tube and its placement in the Tube Holder.

2. Nasal Swab Specimen Collection

• The user is guided through the proper collection of an anterior nasal swab specimen.
• Instructions are provided for adult self-collection or adult-collection (caregiver) of a specimen from a child or another adult (the appropriate workflow is displayed based on the profile the user selected in the app).
• The specimen collection is an anterior nasal swab collection.

3. Specimen Extraction / Processing

• The user is guided through extraction of the specimen from the swab by plunging the swab into the provided Tube (with liquid).
• The user is instructed to discard the swab.

4. Sample Application to the test stick

• The user is instructed to close the top on the dispensing Tube.
• The user is guided through the application of three (3) drops of sample to the Test Stick.

5. Test Stick Scanning and Result Interpretation with the Scanwell Health App

• After sample application, the user is prompted in the app to progress to the next step. This actuates an in-app 15-minute incubation timer.
• When the timer sounds on the cell phone, the user is prompted to scan the Test Stick (the Test Stick must be placed on the Scan Card). The user has 5 minutes to complete the scanning step, after which the test is voided, and the user is instructed to try again with a new test or to contact customer service.
• Several pre-image capture quality checks are built into the scanning step to ensure the image captured is of sufficient quality for analysis. These include checks for low lighting, shadow, Test Stick detection and proximity to the Scan Card, among others. User feedback notifications appear at the top of the screen, instructing the user in real-time how to capture a good image. The app only accepts and analyzes an image if all pre-image capture quality checks are passed.
• On the subsequent screen, the interpreted result is displayed. Negative, Positive and Invalid test results are possible (see Figure 2). An invalid test may occur for several reasons, including the absence of a positive control line, presence of negative control line with intensity above predefined threshold, or sample adequacy line below a predefined threshold.

Results Interpretation

Figure 2 illustrates the interpretation of test results as displayed by the Scanwell Health App:

• POSITIVE: You should self-isolate from others and contact a healthcare provider for medical advice about your positive result. A confirmatory test may be recommended.
• INVALID: There was an error and you should retest with a new test kit. If you have COVID-19 symptoms, you should self-isolate from others until you can retest.
• NEGATIVE: If you have COVID-19 symptoms, you should self-isolate from others and contact a healthcare provider for medical advice about your symptoms. If you do not have COVID-19 symptoms and this is your first test, you must perform a second test (this is called serial testing). Your second test should be taken at least 24 hours and no more than 48 hours after the first test.

Each result screen provides options for "More About This Test", "Where do I find more information?" (linking to Product Information Leaflet and Healthcare Provider Instructions for Use), and "Where can I find a copy of my test result?" (indicating results are saved in the Scanwell app history). Options to "Share Result" and "Speak to BD Customer Care" are also present.

QUALITY CONTROL

The Test Sticks are designed with spatially distinct reaction zones which include positive and negative control line positions, a sample adequacy line position and the test line position for SARS-CoV-2.

Internal Controls

The positive and negative control lines are internal reagent controls designed to assure the Test Stick reagents are viable and that the test has been properly conducted. The sample adequacy line is designed to assess whether the collected nasal specimen is suitable for analysis by detection of an endogenous biomarker, to assure sample validity.

To properly interpret and report the test outcome from multiple lines deposited in the reaction zone, the test system requires the use of the smartphone app to process a scanned image of the Test Stick. There are no markings on the Test Stick housing identifying the different reaction zones, nor are these described in the labeling.

The app interpretation logic factors in the presence or absence of the control lines to determine if the overall result is valid or invalid. If the result is deemed valid, a determination is made to report the test as Negative or Positive. Invalid results may be caused by the absence of a Positive Control Line or Sample Adequacy line below a predetermined threshold, or the presence of a Negative Control Line above a predetermined threshold. The possible combinations of test and control lines result in the reporting of the test as Negative, Positive or Invalid are outlined below in Table 2.

*In the case of a positive SARS-CoV-2 result in the absence of an adequate Sample Adequacy line, the app returns a positive result as a fail-safe against any possible missed detections.

Other Failure Alert and Failsafe Controls

The test also incorporates failure alert and failsafe controls that assure the user is not allowed to continue with the test, rather than receive an invalid result, in the event:

• Home lighting is not appropriate prior to initiation of the test,
• Too much time has elapsed since sample was added to the Test Stick,
• Too much time has elapsed between Test Stick development and scanning,
• Scanning conditions are not conducive to ensure the image captured is of sufficient quality for analysis including low lighting, shadow, Test Stick detection and proximity to the Scan Card, and
• A user attempts to use a different manufacturer's test stick.

LIMITATIONS

• For emergency use only
• For in vitro diagnostic use.
• Do not use the test on children under 2 years of age.
• The test has only been tested in children age 2 and above.
• For children ages 2-13 years, specimens must be collected and tested by an adult (18+ years old).
• Failure to follow the test directions may affect test performance and/or provide incorrect results.
• False negative results are a possible concern, especially if you have symptoms or recently had significant close contact with a person with COVID-19 and when local disease prevalence is high.
• False positive results are a possible concern, especially if you do not have any symptoms when local disease prevalence is low.
• The test performance has only been assessed for use with human nasal swabs.
• Samples collected in viral transport media should not be used with this test.
• Perform the testing of the sample as soon as possible after swabbing the nose.
• Positive test results do not rule out co-infections with other pathogens.
• Negative test results do not preclude infection and should not be used as the sole basis for treatment or other patient management decisions, including infection control decisions, particularly in the presence of clinical signs and symptoms consistent with COVID-19, or in those who have been in contact with the virus.
• Negative results are presumptive, do not rule out COVID-19 infection and it may be necessary to obtain additional testing with a molecular assay, if needed for patient management.
• The contents of this kit are to be used for the qualitative detection of SARS-CoV-2 antigens from nasal swab specimens only. This test can detect both viable and non-viable viral material. The detection of SARS-CoV-2 antigens depends on antigen load and may not correlate with other diagnostic methods.
• Use only the nasal swab provided in the test kit to collect the test specimen.
• Do not re-use any of the test kit components, including the nasal swab.
• The performance of this test has not yet been clinically validated for use in patients without signs and symptoms of respiratory infection, or for serial screening applications and performance may differ in these populations.
• Testing for asymptomatic individuals should be performed at least twice over three days, with at least twenty-four hours and no more than 48 hours between tests. You may need to purchase additional tests to perform this serial (repeat) testing.
• There is a higher chance of false negative results with antigen tests than with laboratory-based molecular tests. This means that there is a higher chance this test will give you a negative result when you have COVID-19.
• Serial testing (i.e., testing every day or every other day) is more likely to detect COVID-19, especially when you do not have any symptoms.
• The performance of this test was established based on the evaluation of a limited number of clinical specimens collected in Spring of 2021. The clinical performance has not been established in 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.

CLINICAL PERFORMANCE

The performance of the BD Veritor™ At-Home COVID-19 Test was established with 597 direct nasal swabs prospectively collected and enrolled from symptomatic individuals (within ten days of symptom onset) who were suspected of COVID-19. As with all antigen tests, performance may decrease as days since symptom onset increase. Specimen collection and testing was performed by the subject (age 14 and older) or their Parent/Legal Guardian/Companion (age 2 and older) at the testing site, unassisted by the study staff and according to the product labeling in eleven geographically diverse areas across the United States. Reference nasal swabs were collected by a healthcare professional and tested with the comparator method in a blinded fashion. The performance of the BD Veritor™ At-Home COVID-19 Test was compared to results of a nasal swab stored in 3 mL viral transport media tested with an Emergency Use Authorized molecular (RT-PCR) test for detection of SARS-CoV-2.

A total of 648 compliant subjects were enrolled into the study, of which 638 had a compliant BD Veritor app result for the invalid rate analysis. The invalid rate for the BD Veritor™ At-Home COVID-19 Test was calculated to be 1.6% (10/638). The invalid rate was calculated by the number of invalid results over the total number of compliant BD Veritor app results. Of the 638 compliant BD Veritor app results, those with an invalid result were removed (10) as well as 31 subjects who were missing a complaint reference RT-PCR result, leaving 597 subjects for performance calculation. The performance of this test has not yet been clinically validated for use in patients without signs and symptoms of respiratory infection, or for serial screening applications and performance may differ in these populations.

Performance of the BD Veritor™ At-Home COVID-19 Test is presented in Table 3.

ANALYTICAL PERFORMANCE

LIMIT OF DETECTION (ANALYTICAL SENSITIVITY)

The LoD for the BD Veritor™ At-Home COVID-19 Test was established using limiting dilutions of a viral sample inactivated by gamma irradiation. The material was supplied at a concentration of 2.8 x 10⁵ TCID₅₀/mL.

In this study, designed to estimate the LoD of the test when using nasal clinical matrix, an initial range finding study was performed testing devices in triplicate using a 10-fold dilution series. At each dilution, 50 µL samples were added to swabs and then tested through the full assay workflow, from processing in the extraction reagent to interpretation by the Scanwell Health App.

A concentration was chosen between the last dilution to give three positive results and the first to give three negative results. Using this concentration, the LoD was further refined with a 2-fold dilution series. The last dilution demonstrating 100% positivity was then tested in an additional 20 replicates tested in the same way. The BD Veritor™ At-Home COVID-19 Test LoD is shown in Table 6.

Table 6: BD Veritor™ At-Home COVID-19 Test Limit of Detection

CROSS REACTIVITY (ANALYTICAL SPECIFICITY)

A cross-reactivity study was conducted to demonstrate that the BD Veritor™ At-Home COVID-19 Test does not react with related pathogens, high prevalence disease agents, and normal or pathogenic flora that are reasonably likely to be encountered in the respiratory tract. The starting material was spiked into a volume of pooled clinical matrix obtained from healthy donors and confirmed negative for SARS-CoV-2. Samples were added to swabs and then tested through the full assay workflow, from processing in the extraction reagent to interpretation by the Scanwell Health App. Each organism and virus was tested in triplicate. Testing of the following related and high prevalence disease agents showed no evidence of cross-reactivity at the concentrations tested except for SARS-Coronavirus at a concentration of 3.3 x 10⁵ PFU/mL (see Table 7). Two lower concentrations of SARS-Coronavirus were tested, and cross reactivity was not observed at the lower concentrations.

Table 7: BD Veritor™ At-Home COVID-19 Test Cross Reactivity Testing Results

Using the Basic Local Alignment Search Tool (BLAST) managed by the National Center for Biotechnology Information (NCBI), in silico analysis was conducted for those organisms that could not be sourced for wet testing. Two blast searches were performed, each of which compared the SARS-CoV-2 nucleocapsid protein sequence against sequence database information from one other microorganism listed below. The degree of sequence homology was then assessed to estimate the likelihood of cross-reactivity with SARS-CoV-2.

• No protein sequence homology was found between SARS-CoV-2 and M. tuberculosis, and thus homology-based cross-reactivity while unlikely, cannot be completely ruled out.
• The comparison between SARS-CoV-2 nucleocapsid protein and human coronavirus HKU1 revealed that the only potential for homology is with the HKU1 nucleocapsid phosphoprotein. Homology is relatively low, at 36.7% across 82% of sequences, but cross-reactivity cannot be ruled out.

ENDOGENOUS INTERFERING SUBSTANCES

An endogenous interference study was conducted to evaluate whether various substances that might be present in the respiratory tract or might be artificially introduced onto the nasal swab in the home environment, interfere with the BD Veritor™ At-Home COVID-19 Test. The study results demonstrate that at the concentrations tested none of the potential interfering substances produced false positive results when present in SARS-CoV-2 negative samples or false negative results when present in SARS-CoV-2 positive samples. No invalid results were produced in either condition. (see Table 8).

Table 8: BD Veritor™ At-Home COVID-19 Test Endogenous Interfering Substances Testing Results

MICROBIAL INTERFERENCE

The purpose of this study was to evaluate whether microbes that are likely to be encountered in the respiratory tract, either as disease agents or as normal pathogenic flora, will interfere with the BD Veritor™ At-Home COVID-19 Test. The study demonstrated that false negatives will not occur when SARS-CoV-2 is present in a specimen at 3x LOD with the following related and high prevalence disease agents at the concentrations tested. No microbial interference was observed (see Table 9).

Table 9: BD Veritor™ At-Home COVID-19 Test Microbial Interference Testing Results

HIGH DOSE HOOK EFFECT

A high-dose hook effect study was conducted to evaluate if false negative or invalid results can be observed on the BD Veritor™ At-Home COVID-19 Test with very high levels of SARS-CoV-2 or human serum albumin (HSA).

No high-dose hook effect was observed on the BD Veritor™ At-Home COVID-19 Test when tested with gamma-irradiated SARS-CoV-2 and HSA, at concentrations of 2.8 ×10⁶ TCID₅₀/mL and 1.021 × 10³ µg/mL, respectively.

HUMAN USABILITY & USER COMPREHENSION STUDY

BD conducted a study to evaluate the usability of the BD Veritor™ At-Home COVID-19 Test and home user comprehension of the intended use and results interpretation. The human usability and user comprehension study included participants from the multi-site clinical trial and a supplemental caregiver collection study. User satisfaction with the BD Veritor™ At-Home COVID-19 Test workflow, materials, and overall safety were also evaluated.

Seven hundred sixty-eight (768) home users, including self-collection participants (n=693) and caregivers (n=75) took part in the study. The study was conducted with home users in a simulated home use setting where the participant/caregiver performed the test using only the materials in the BD Veritor™ At-Home COVID-19 Test kit box (Test Stick, Tube, Scan Card, Swab, Quick Start Guide, and Product Information Leaflet) and the Scanwell Health App.

For all participants (self-collection and caregiver) in the study, all but one of the critical tasks had a success rate over 94%. The task “Rotate the swab in first nostril for 5 times” had a success rate of 85.7% (658 of 768), however the task “Rotate the swab in second nostril for 5 times” which is an identical task, had 94.1% (723 of 768) success rate, demonstrating an improvement in the task from the initial task learning.

All study participants were asked to fill out a satisfaction questionnaire rating the ease-of-use, quality of the instructions for use, safety concerns, and their confidence in the test result. All 10 questions presented in the questionnaire received a rating of 4.2 or above (on a scale of 1 to 5).
