bd max covid sensitivity and specificity

BioFire has brought its syndromic approach to COVID-19 testing. The “gold standard” for clinical diagnostic detection of SARS-CoV-2 remains NAATs, such as RT-PCR. COVID-19 resources and guidelines for labs and laboratory workers. Detection of these relatively distant members of the SARS-related CoV clade suggests that all Asian viruses are likely to be detected. Over the last two months, UC Davis Health clinical pathology departments were heavily involved in validating molecular COVID tests on four different platforms: AB StepOne Plus, Roche 6800, GenMark and BD Max. 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. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. 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. If a specific testing site, such as a nursing home, has a test positivity rate near zero, the prevalence of disease in the community (e.g., cases among the population) should instead be used to help determine pretest probability. 6If prevalence of infection is not low in the community, clinical discretion should consider whether this negative antigen result requires confirmation See CDC’s guidance for Isolation. COVID‐19 patients were more likely to be male (61% vs 20%; P = .0001) ... which had a 71.1% sensitivity and 96.2% specificity against PCR‐confirmed COVID‐19 diagnosis, resulting in 97.2% PPV and 64.6% NPV. See CDC’s guidance for Quarantine; clinical discretion should determine if and when additional testing is necessary. Performance of Antigen Tests for SARS-CoV-2, Processing of Antigen Tests for SARS-CoV-2, Evaluating the Results of Antigen Tests for SARS-CoV-2. When a symptomatic person receives a negative antigen test result followed by a negative confirmatory NAAT, the healthcare provider should take into consideration whether the person has had exposure to a person with COVID-19 within the past 14 days. Confirmatory testing should take place as soon as possible after the antigen test, and not longer than 48 hours after the initial antigen testing. The Conditions of Authorization in the antigen EUAs specify that CLIA-certified laboratories and testing sites are to follow the manufacturer’s instructions for use, typically found in the package insert, when performing the test and reading test results. 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. Laboratories and testing sites should refer to the instructions for use and the package insert that are specific for the test that they are using regarding the use of VTM. 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 CDC recommends using a NAAT that has been evaluated against the FDA reference panel for analytical sensitivity. The BioGX SARS-CoV-2 Reagents for BD MAX ™ System is a real-time RT-PCR test intended for the qualitative detection of nucleic acid from the SARS-CoV-2 in nasopharyngeal and oropharyngeal swab samples from individuals suspected of COVID-19 by their healthcare provider. The Sofia SARS Antigen FIA, with the Sofia 2 and Sofia analyzers, provides automated and objective results in 15 minutes, allowing for testing of patients suspected of COVID-19/2019-nCoV in near-patient testing environments. 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. 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.

CMS has provided additional information on Enforcement discretion for the use of SARS-CoV-2 point-of-care testing on asymptomatic individuals.pdf iconexternal icon. Evaluating the results of an antigen test for SARS-CoV-2 should take into account the performance characteristics (e.g., sensitivity, specificity) and the instructions for use of the FDA-authorized assay, the prevalence of SARS-CoV-2 infection in that particular community (positivity rate over the previous 7–10 days or the rate of cases in the community), and the clinical and epidemiological context of the person who has been tested. In this moderate pretest probability scenario, the healthcare provider should consider performing a NAAT first if short test turnaround time is available, if the person cannot be effectively and safely quarantined, or if there are barriers to possible confirmatory testing (e.g., travel barriers for follow-up testing, tolerance of multiple specimen collections). See the antigen testing algorithm when pretest probability is high, Figure 2, which is excerpted directly from the full antigen testing algorithm in Figure 1. When testing a person who is asymptomatic and has had exposure to a person with COVID-19 within the last 14 days, indicating that the pretest probability is moderate, the healthcare provider should confirm a positive antigen test result with an FDA-authorized NAAT. See CDC’s guidance for Quarantine; clinical discretion should determine if and when additional testing is necessary. 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. 0 It may not be necessary to perform confirmatory testing with a NAAT when conducting serial antigen testing on those who have received a negative antigen test result. 1. 9Isolation is necessary. Sensitivity was 89% for nasopharyngeal swabs and 72% for saliva (P = .02). 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.”. Testing a symptomatic person – high 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… 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. However, several studies have documented persistent detection of virus using RT-PCR after recovery; in these cases, the persons did not seem to be infectious to others. 10Quarantine is necessary. Generally, clinicians can rely upon a positive antigen test result for a symptomatic patient because the specificity of current FDA-authorized antigen tests is high. 8Known exposure to a person with COVID-19 within the last 14 days; if unsure, clinical discretion should determine whether isolation is necessary Enforcement discretion for the use of SARS-CoV-2 point-of-care testing on asymptomatic individuals. 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). You will be subject to the destination website's privacy policy when you follow the link. See CDC’s Clinical Questions about COVID-19: Questions and Answers. Two studies were completed to determine clinical performance. Sensitivity and specificity are measures of a test's ability to correctly classify a person as having a disease or not having a disease. endstream endobj startxref 5In certain settings, serial antigen testing could be considered for those with a negative antigen test result; serial testing may not require confirmation of negative results. For example, the performance of antigen tests can be affected if the test components are not stored and handled properly. 1,2,3,4 Traditional diagnostic techniques tend to be subjective with variable sensitivity and specificity. CDC recommends following its antigen testing algorithm (Figure 1 below, also available as PDF pdf icon[PDF – 457 KB]) to determine when confirmatory testing is recommended. Sir John Bell, Regius Professor of Medicine at Oxford University , said: 'The data in this validation report demonstrates that these inexpensive, easy to use tests can play a major role in our fight against COVID 19. 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. Serial testing, particularly in congregate settings when it has been possible to quarantine persons for 14 days, should not continue indefinitely. CDC has also provided a Summary of considerations for using antigen tests in nursing homes. Persons who receive a positive antigen test result that should undergo confirmatory testing should isolate while awaiting results of the confirmatory testing. This guidance supplements and is consistent with CDC’s Overview of Testing for SARS-CoV-2 guidance. Becton, Dickinson & Company: BD SARS-CoV-2 Reagents for BD MAX System: Results were … Through two sequential CNNs, they were automatically distinguished from normal lymphocytes and classical RL with sensitivity, specificity and overall accuracy values of 90.5%, 99.4% and 98.7%, respectively. See Table 1 for additional information about antigen tests. For more information, see CMS’ How to Obtain a CLIA Certificatepdf iconexternal icon. Ellume's test results provided to the FDA showed the test demonstrated a sensitivity of 96 percent and specificity of 100 percent among individuals with COVID-19 symptoms. Linking to a non-federal website does not constitute an endorsement by CDC or any of its employees of the sponsors or the information and products presented on the website. Pretest probability considers both the prevalence of the target infection in the community as well as the clinical context of the individual being tested. 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. Two of our patients were receiving immunosuppressive agents at COVID diagnosis. Introduction . See FDA’s list of In Vitro Diagnostics EUAsexternal icon. Healthcare professionals can purchase the Sofia SARS Antigen FIA through select authorized distributors. See CDC’s guidance for Isolation. Test sensitivity for rapid antigen tests is generally lower than for RT-PCR. The first showed that the IgG results displayed a 95% specificity in a cohort of PCR‐confirmed COVID‐19 cases, without comparing the IgG serology results to results obtained with an IgG serology reference method. Antigen Testing Algorithm – Moderate Pretest Probability. BioFire’s Respiratory Solutions with SARS-CoV-2. Antigen Testing Algorithm – Low Pretest Probability. See CDC’s guidance on Testing in Nursing Homes and FDA’s Recommendations for healthcare providers using SARS-CoV-2 diagnostic tests for screening asymptomatic individuals for COVID-19external icon. Figure 2. Antigen tests can be used for screening testing in high-risk congregate settings in which repeat testing could quickly identify persons with a SARS-CoV-2 infection to inform infection prevention and control measures, thus preventing transmission. reported the sensitivity and specificity of the BD MAX Cdiff assay as 93.4% and 97.3% and the ribotype diversity did not appear to affect the performance of the BD MAX Cdiff assay. b) Among 4220 patients who were negative on their first testing episode, and subsequently retested, only 85/4220 (2.5%) flipped from negative to positive. Also see CMS’ Enforcement discretion for the use of SARS-CoV-2 point-of-care testing on asymptomatic individualspdf iconexternal icon. 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 352 0 obj <> endobj 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. 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 BD clinical studies performed at more than 20 sites across the U.S. demonstrated that the test is capable of achieving 84% sensitivity and 100% specificity, which is in line with the performance from similar immunoassay tests for Flu A/B, RSV and Strep A on the BD Veritor™ Plus System — all of which are widely-used, highly relevant and clinically valid. All testing for SARS-CoV-2, including antigen testing, depends on the integrity of the specimen, which is affected by procedures for both specimen collection and handling. The findings of high-throughput genomic sequencing of SARS-CoV-2 are regularly deposited on the global initiative on sharing all influenza data (GISAID) .The development of oligonucleotides (primers and probes) for molecular diagnosis of COVID-19 was initiated as soon as these findings were made public on 10th Jan 2020 , .CDC (USA), China CDC, Charité Germany, Institut … 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. 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 Because of concerns about false positive results when pretest probability is low, a positive antigen test result in this circumstance should be followed by a confirmatory NAAT, recognizing that the person will be tested at a later timepoint in their illness if truly infected. 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. The purpose of this interim technical guidance is to support effective clinical use of antigen tests for different testing situations. 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. 4In instances of higher pretest probability, such as high incidence of incidence of infection in the community, clinical discretion should determine if this positive antigen result requires confirmation In general, the lower the prevalence of infection in the community, the higher the rate of false positive test results. Positive and negative predictive values of all in vitro diagnostic tests (e.g., NAAT and antigen assays) vary depending upon the pretest probability. Becton Dickinson and Co.’s 15-minute COVID-19 test has been cleared for use in countries that accept Europe’s CE marking. 4In instances of higher pretest probability, such as high incidence of incidence of infection in the community, clinical discretion should determine if this positive antigen result requires confirmation State health departments generally publish COVID-19 data on testing positivity rates and case rates for their communities. 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 … 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 … Quality assurance procedures should be followed to prevent cross-contamination and inaccurate test results.
