Roche announced today that it intends to launch a high-volume SARS-CoV-2 Antigen test as an aid in the diagnosis of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection. The test is planned to be made available at the end of 2020 for markets accepting the CE Mark. Roche also intends to file for Emergency Use Authorisation (EUA) from the U.S. Food and Drug Administration (FDA).
The Elecsys SARS-CoV-2 Antigen test is a highly accurate laboratory immunoassay for the in vitro qualitative detection of the nucleocapsid antigen of SARS-CoV-2. The test is performed by healthcare professionals and uses nasopharyngeal or oropharyngeal swab samples from patients with signs and symptoms suggestive of COVID-19, or people with either known or suspected exposure to SARS-CoV-2.
The Elecsys SARS-CoV-2 Antigen immunoassay runs on all cobas e immunochemistry analysers which are widely available around the world. These fully automated systems can provide test results in 18 minutes for a single test (excluding time for sample collection, transport, and preparation), with a throughput of up to 300 tests per hour from a single analyser, depending on the analyser.1 A laboratory based automated antigen assay allows for cost and error reduction due to removal of manual handling as well as fast turn-around times and high test throughput.
Thomas Schinecker, CEO Roche Diagnostics, stated, “We are aware that governments and healthcare systems are under intense pressure to increase SARS-CoV-2 testing capacity to effectively manage the spread of the virus. A high-volume antigen test is a valuable addition to the testing portfolio for helping diagnose SARS-CoV-2 infection. Being able to quickly and correctly identify if someone has a SARS-CoV-2 infection is critical to informing patient management decisions and containing the spread of COVID-19. Roche remains committed to supporting governments, healthcare professionals and patients to fight this pandemic with the help of our diagnostics solutions.’
The test will be another addition to the comprehensive Roche diagnostic portfolio of solutions to help healthcare systems combat COVID-19 through testing in the laboratory and at the point of care. These solutions include both tests to detect an acute SARS-CoV-2 infection and tests measuring the body’s immune response upon infection or vaccination. The following table provides an overview of Roche’s current COVID-19 test portfolio for the detection of an acute SARS-CoV-2 infection or immune response:

About the Elecsys SARS-CoV-2 Antigen testRoche’s Elecsys SARS-CoV-2 Antigen test is an immunoassay intended for the qualitative detection of a specific antigen of SARS-CoV-2 present in the respiratory tract including nasopharynx and oropharynx. The Elecsys SARS-CoV-2 Antigen test is performed by healthcare professionals and could be used as an alternative or in conjunction with PCR testing. This is highly beneficial where reliable laboratory PCR testing is not available or where there are challenges in testing capacity. A positive result with the Elecsys SARS-CoV-2 Antigen test most likely indicates an active SARS-CoV-2 infection. A negative result may require to be confirmed with a PCR test or repeated (antigen test) after one to two days, if other clinical indications point to a SARS-CoV-2 infection. Performance evaluations around sensitivity and specificity of the test are ongoing and will be shared at the time of launch.
About antigen testingAn antigen test detects proteins which are structural or functional components of a pathogen and are thus very specific to that pathogen.2 In this case, the test would provide a qualitative “yes/no? answer on the presence of the pathogen in the patient sample. If the target antigen is present in sufficient concentrations in the sample, it will bind to specific antibodies and generate a positive result.3
In general, antigen tests have a high specificity, though are not as sensitive as PCR tests that amplify the target viral DNA or RNA sequence in order to generate a quantifiable signal to indicate the presence of the virus in a sample. Therefore, to make up for the potential decrease in sensitivity of an antigen test, negative results should be analysed together with additional patient factors, such as COVID-19 exposure history, clinical symptoms, additional test results to help guide the diagnosis and subsequent treatment of the patient.
About Roche’s response to the COVID-19 pandemicAs a leading healthcare company we are doing all we can to support countries in minimising the impact of COVID-19. We have developed a growing number of diagnostic solutions that help to manage, detect and diagnose current and/or previous infection in patients, as well as providing digital support to healthcare systems. We continue to identify, develop and support potential therapies which can play a role in treating the disease.
We understand the impact of COVID-19 goes beyond those who contract it, which is why we are working with healthcare providers, laboratories, authorities and organisations to help make sure that patients continue to receive the tests, treatment and care they need during these challenging times. As we learn from the pandemic, we are partnering with governments and others to make healthcare stronger and more sustainable in the future.
Our diagnostics solutions:
Reliable, high-quality testing is essential to help healthcare systems overcome this pandemic. Our portfolio includes:
- a high-volume molecular test to detect SARS-CoV-2, the virus that causes COVID-19, (FDA Emergency Use Authorisation (EUA) and available in countries accepting the CE Mark)
- a SARS-CoV-2 laboratory-based qualitative antibody test, aimed at detecting the presence of antibodies in the blood targeting the nucleocapsid protein (FDA EUA and CE Mark)
- an IL-6 test to assist in identifying severe inflammatory response in patients with confirmed COVID-19 (FDA EUA and CE Mark)
- Roche v-TAC, which could help simplify the screening, diagnosis and monitoring of patients with respiratory compromise in the current COVID-19 pandemic
- a SARS-CoV-2 rapid antibody test to help determine at the point of care whether a person has been exposed to the virus (CE Mark)
- a rapid antigen test to support in the detection of SARS-CoV-2 at the point of care within 15 minutes (CE Mark)
- a high-volume molecular test to simultaneously detect and differentiate between SARS-CoV-2 and influenza A/B, as the symptoms are similar for both (FDA EUA and CE Mark)
- a second SARS-CoV-2 antibody test, aimed at measuring the spike protein to support vaccination development and complement our existing portfolio (CE Mark)
Our research into therapies:
Roche is committed to improving the treatment of COVID-19. We are actively involved in understanding the potential of our existing portfolio and are exploring the potential of our investigational molecules.
Specifically, on 19 March, we announced the initiation of COVACTA - a global Phase III randomised, double-blind, placebo-controlled clinical trial to evaluate the safety and efficacy of intravenous Actemra (tocilizumab) plus standard of care in hospitalised adult patients with severe COVID-19 pneumonia compared to placebo plus standard of care. On 29 July we announced that COVACTA did not meet its primary endpoint of improved clinical status in patients with COVID-19 associated pneumonia or the key secondary endpoint of reduced mortality.
in the EMPACTA study in COVID-19 associated hospitalised pneumonia in patients that are often underrepresented in clinical trials. On 18 September we announced that the phase III EMPACTA study showed Actemra/RoActemra plus standard of care reduced the likelihood of progression to mechanical ventilation or death in hospitalised patients with COVID-19 associated pneumonia compared to placebo plus standard of care. However, there was no statistical difference in mortality between patients who received Actemra/RoActemra or placebo.
is also being studied in combination with the investigational antiviral remdesivir in hospitalised patients with severe COVID-19 pneumonia in the REMDACTA trial in partnership with Gilead, announced 28 May. Actemra is not approved by any health authority for use in COVID-19 pneumonia. Roche has further initiated an internal early research programme focused on the development of medicines for COVID-19 and is engaged in multiple research collaborations.
In August we signed a collaboration agreement with Regeneron on developing and manufacturing and significantly increasing global supply of an investigational antibody combination for COVID-19 if it proves safe and effective in clinical trials and regulatory approvals are granted.
In these exceptional times, Roche stands together with governments, healthcare providers and all those working to overcome the pandemic.
