Clinical judgement should determine if and when additional testing is necessary. The healthcare provider should direct the person who received a negative antigen test result, or a negative confirmatory NAAT result, to quarantine for 14 days after the last known exposure to a person with COVID-19. ECDC agrees with the minimum performance requirements set by WHO at ≥80% sensitivity and ≥97% specificity.

BioGX SARS-CoV-2 Reagents for BD MAX ™ System. The specificity of antigen tests is generally as high as most NAATs, which means that false positive test results are unlikely when an antigen test is used according to the manufacturer’s instructions. Testing an asymptomatic person who has had close contact with a person with COVID-19 – moderate pretest probability. The BD SARS-CoV-2 Reagents for BD MAX System utilizes multiplexed primers and probes targeting RNA from the nucleocapsid phosphoprotein gene (N1 and N2 regions) of the SARS-CoV-2 coronavirus… Two studies were completed to determine clinical performance. The purpose of this interim technical guidance is to support effective clinical use of antigen tests for different testing situations. See CDC’s Clinical Questions about COVID-19: Questions and Answers. In response to the coronavirus disease 2019 (COVID-19) pandemic, the US Food and Drug Administration issued emergency authorization for use of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid amplification tests (NAATs) to diagnose COVID-19 [].Despite widespread use of SARS-CoV-2 molecular testing, its clinical sensitivity remains uncertain. The analytical sensitivity of the Xpert test (EUA version) was assessed with one lot of reagent and limiting dilutions of the quantitated SARS-CoV-2 (USA_WA1/2020) according to standard guidelines ().The virus stock (9.75 × 10 5 PFU/ml) was obtained from the University of Texas Medical Branch Arbovirus Reference Collection, Galveston, TX. Clinicians, laboratory and testing professionals, and public health practitioners should also understand the differences among diagnostic, screening, and surveillance testing. Also see information from the Centers for Medicare & Medicaid Services (CMS) on Enforcement discretion for the use of SARS-CoV-2 point-of-care testing on asymptomatic individuals.pdf iconexternal icon. See EPA’s List of Disinfectants for COVID-19external icon. The test leverages the design principles of our current Xpert® Xpress Flu/RSV cartridge technology, in which multiple regions of the viral genome are targeted. The recent spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exemplifies the critical need for accurate and rapid diagnostic assays to prompt clinical and public health interventions. Positive and negative predictive values of all in vitro diagnostic tests (e.g., NAAT and antigen assays) vary depending upon the pretest probability. Rapid antigen tests perform best in cases with high viral load, in pre-symptomatic and early symptomatic cases up to five days from symptom onset. A CLIA-certified laboratory or testing site must report antigen diagnostic test results to the local, state, tribal, or territory health department in accordance with Public Law 116-136, § 18115(a), the Coronavirus Aid, Relief, and Economic Security (CARES) Act. 3If a symptomatic person has a low likelihood of SARS-CoV-2 infection, clinical discretion should determine if this negative antigen test result requires confirmatory testing See CDC’s Indicators and thresholds for risk of introduction and transmission of COVID-19 in schools. Panbio COVID-19 Antigen Rapid Test IFU. Serial testing, particularly in congregate settings when it has been possible to quarantine persons for 14 days, should not continue indefinitely. Failing to change gloves can increase the risk of cross-contamination and false antigen test results. Hospitals and laboratories are faced with increasing challenges in managing workload and patient needs. CDC considers low prevalence to be when NAAT positivity over the last 14 days is less than 5% or when there are fewer than 20 new cases of COVID-19 per 100,000 persons within the last 14 days. Test sensitivity for rapid antigen tests is generally lower than for RT-PCR.

Testing an asymptomatic person with no known exposure to a person with COVID-19 – low pretest probability. Time from sample collection to testing should be minimized, and the temperature of the specimen during this time must be controlled. Clinicians and public health practitioners should understand test performance characteristics to recognize potentially false negative or false positive test results and to guide additional confirmatory testing and patient management. Decontaminate work surfaces and equipment with appropriate disinfectants by using an EPA-approved disinfectant for SARS-CoV-2, following the manufacturer’s recommendations for use, such as dilution, contact time, and safe handling. The BD MAX system is cleared or approved by the U.S. FDA only when used with BD MAX ™ IVD assays, which have been cleared or approved by the FDA. Persons who receive a positive antigen test result that should undergo confirmatory testing should isolate while awaiting results of the confirmatory testing. Antigen tests are currently authorized to be performed on nasopharyngeal or nasal swab specimens placed directly into the assay’s extraction buffer or reagent. Both antigen tests and NAATs perform best when the person is tested when viral load is generally highest. Objectives: New molecular tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are being rapidly launched in response to the coronavirus disease 2019 (COVID-19) pandemic. In instances of higher pretest probability, such as high incidence of infection in the community, or a person with household or continuous contact to a person with COVID-19, clinical judgement should determine if a positive antigen result for an asymptomatic person should be followed by a confirmatory NAAT. Analytical performance. 0 Laboratory and testing professionals who perform antigen tests should understand the factors that affect the accuracy of antigen testing, as described in this guidance.

Table 1 summarizes the differences between NAATs and antigen tests. See FDA’s list of In Vitro Diagnostics EUAsexternal icon. Depending on the stipulations of the FDA authorization, the laboratory or testing site may be required to report negative test results to patients as “presumptive negative.”. BD Statement on COVID-19 (Coronavirus) Updated November 2020. The role of a negative antigen test result in ending quarantine depends upon when it is performed in the quarantine period. The currently authorized antigen tests are not restricted to use on persons of a certain age. See CDC’s guidance for Quarantine; clinical discretion should determine if and when additional testing is necessary. The package insert for antigen tests also includes instructions about how to read the test results, including the appropriate time to read the results and whether the results should be interpreted visually or with an instrument analyzer. 9Isolation is necessary. ... Not all viral tests have equivalent sensitivity and specificity. SARS -CoV -2 has emerged as a novel cause of human infection, causing a global pandemic in the first 6 months of 2020, with >8.2 million confirmed cases of infection and 443K deaths (1). 10Quarantine is necessary. See CDC’s guidance on Testing in Nursing Homes, Quarantine and Isolation, Discontinuation of Isolation for Persons with COVID-19 Not in Healthcare Settings, Discontinuation of Transmission-Based Precautions of Patients in Healthcare Settings, and Return to Work for Healthcare Personnel. 1Single, multiple, or continuous known exposure to a person with COVID-19 within the last 14 days; perform NAAT first if short turnaround time is available, if person cannot be effectively and safely quarantined, or if there are barriers to possible confirmatory testing When testing a person who has symptoms associated with COVID-19, indicating that pretest probability is high, the healthcare provider generally can interpret a positive antigen test to indicate that the person is infected with SARS-CoV-2. ZARAGOZA, Spain and FRANKLIN LAKES, N.J., March 10, 2020 /PRNewswire/ -- CerTest Biotec, along with BD (Becton, Dickinson and Company) (NYSE: BDX), a leading global medical technology company, today announced that the VIASURE SARS-CoV-2 Real Time PCR Detection Kit adapted for the BD MAX ™ System has been CE marked to the IVD Directive (98/79/CE). State health departments generally publish COVID-19 data on testing positivity rates and case rates for their communities. Note: Antigen tests can be used in a variety of testing strategies to respond to the coronavirus disease 2019 (COVID-19) pandemic. 5. This means, when you use your BD Veritor™ Plus System you might see 0-2 false positives for every 100 tests you conduct. The U.S. Food and Drug Administration (FDA) has granted emergency use authorization (EUA) for antigen tests that can identify SARS-CoV-2. For example, users should follow the manufacturer’s instructions, as well as state and local guidance, for when and how often to perform testing on control specimens. The possibility of coronavirus disease 2019 (COVID-19) should be considered in patients with compatible symptoms , in particular fever and/or respiratory tract symptoms, who reside in or have traveled to areas with community transmission or who have had recent close contact with a confirmed or suspected case of COVID-19. Xpert® Xpress SARS-CoV-2* Cepheid has developed an automated molecular test for the qualitative detection of SARS-CoV-2, the virus that causes COVID-19. Third, colchicine is the drug of choice for the prevention of recurrent mucocutaneous lesions of BD. See CDC’s Interpreting Results of Diagnostic Tests for additional information on the relationship between pretest probability and the likelihood of positive and negative predictive values. Revisions were made on December 5, 2020 including: Note: Antigen tests can be used in a variety of testing strategies to respond to the coronavirus disease 2019 (COVID-19) pandemic. Processing multiple specimens successively or in batch mode may make it more challenging to ensure that each specimen is incubated for the correct amount of time before the result is read. 352 0 obj <> endobj If the prevalence of infection in the community is high, and the person being tested is symptomatic, then the pretest probability is generally considered high. In November, the U.S. Food and Drug Administration (FDA) approved the first rapid COVID-19 test for at-home use. And rapid COVID-19 testing is only going to become more widespread. There is some variation in the sensitivity of ... • False positive results have been reported with the BD Max SARS-CoV-2 RT-PCR reagents on the BD Max system. Also see FDA’s Letter to Clinical Laboratory Staff and Health Care Providersexternal icon on the potential for false positive results with antigen tests, and CDC’s guidance on Point-of-Care Testing. It is important for clinicians and testing personnel to understand the analytic performance characteristics, including sensitivity, specificity, and positive and negative predictive values, of the particular antigen test being used, and to follow the manufacturer’s instructions and package insert. The sensitivity of current FDA-authorized antigen tests varies, and thus negative diagnostic testing results should be handled differently depending on the test, its stated performance characteristics, and intended application (e.g., clinical diagnosis, screening). Vaginitis is the most common women's health issue, accounting for more than 10 billion cases each year. To help estimate pretest probability, CDC recommends that laboratory and testing professionals who perform antigen testing determine infection prevalence based on a rolling average of the positivity rate of their own SARS-CoV-2 testing over the previous 7–10 days. See FDA’s In Vitro Diagnostics EUAsexternal icon for detailed information about the performance of specific authorized tests. Testing for COVID-19: PCR, Antigen, and Serology . If the prevalence of infection in the community is low, and the person being tested is asymptomatic and has not had any known contact to a person with COVID-19, then the pretest probability is generally considered low. See CDC’s Interim Guidelines for Collecting, Handling, and Testing Clinical Specimens for COVID-19. We compared the performance of the BD Max enteric parasite panel to routine microscopy and an in-house PCR for the detection of Giardia intestinalis, Entamoeba histolytica, and Cryptosporidium spp. 2No known exposure to a person with COVID-19 within the last 14 days 8Known exposure to a person with COVID-19 within the last 14 days; if unsure, clinical discretion should determine whether isolation is necessary In addition to validating the sensitivity, specificity and detection limits of these instruments, the team also validated many kinds of viral transport media and swabs to ensure … Serial antigen testing within a closed congregate setting, such as a long-term care facility or a correctional or detention facility, could quickly identify someone with a SARS-CoV-2 infection and prevent further transmission. ID NOW COVID -19 is an automated assay that utilizes isothermal nucleic acid amplification technology for the qualitative detection of SARS-CoV-2 viral nucleic acids. %%EOF 7Nucleic acid amplification test; confirm within 48 hours using a NAAT, such as RT-PCR, that has been evaluated against FDA’s reference panel for analytical sensitivity Modeling evidenceexternal icon shows that outbreak control depends largely on the frequency of testing, the speed of reporting, and the application of interventions, and is only marginally improved by the sensitivity of the test. Becton Dickinson & Co. won a U.S. regulator’s approval for a portable Covid-19 test that delivers results in 15 minutes. BioFire has brought its syndromic approach to COVID-19 testing. The CARES Act requires “every laboratory that performs or analyzes a test that is intended to detect SARS-CoV-2 or to diagnose a possible case of COVID-19” to report the results of each such test. We enrolled 91 consecutive inpatients with COVID-19 at 6 hospitals in Toronto, Canada, and tested 1 nasopharyngeal swab/saliva sample pair from each patient using real-time RT-PCR for severe acute respiratory syndrome coronavirus 2. The evaluation of an antigen test result should consider whether, and if so the length of time, the patient has experienced symptoms. Evaluating the Results of Antigen Testing for SARS-CoV-2. See each test’s instructions for use at FDA’s In Vitro Diagnostics EUAsexternal icon, and see FDA’s Recommendations for healthcare providers using SARS-CoV-2 diagnostic tests for screening asymptomatic individuals for COVID-19external icon. Laboratory and testing professionals who conduct diagnostic or screening testing for SARS-CoV-2 with antigen tests must also comply with Clinical Laboratory Improvement Amendments (CLIA) regulations. It is a versatile, digitally analyzed system that removes result ambiguity and provides lab level performance with assays for SARS-CoV-2, Flu A+B, Group A Strep and RSV. If the prevalence of SARS-CoV-2 infection is not low in the community, clinical judgement should consider whether this negative antigen test result should be followed by a confirmatory NAAT. Antigen Testing Algorithm – High Pretest Probability. If antigen testing returns multiple unexpected positive results, it may be appropriate to stop testing patient specimens, review all procedures, disinfect all surfaces, change gloves, and run control specimens before restarting the testing of patient specimens. FDA regulates in vitro diagnostic devices and has provided recommendations and information regarding EUA requests for COVID-19 diagnostic tests in the Policy for Coronavirus Disease-2019 Tests During the Public Health Emergency (Revised) (“Policy for COVID-19 Tests”)external icon and the EUA templates referenced in that policy. CDC has also provided a Summary of considerations for using antigen tests in nursing homes. BD Veritor™ Plus System has a 98%-100% specificity, which means the false positive rate is less than 2% of all the tests performed. Healthcare providers should consider pretest probability when using antigen tests as screening tests, and confirmatory testing may be required for clinical management and public health decision-making. Previous reports have indicated that the sensitivity of chest computed tomography (CT) in the diagnosis of COVID-19 may be greater than 90% [1,2]. Facilities should refer to CDC’s LOINC In Vitro Diagnostic (LIVD) Test Code Mapping for SARS-CoV-2 Tests. Figure 4.
