Roche's COVID-19 Antibody Test Now Available at U.S. Lab Sites

By PR Newswire | 05.20.20

LabCorp and more than 20 other commercial and hospital labs will be able to perform over 2 million tests per week by June.

Roche has announced its Elecsys Anti-SARS-CoV-2 antibody test is live at more than 20 commercial and hospital lab sites throughout the United States, with plans in the next several weeks to increase to more than 200 commercial and hospital lab sites with the ability to perform millions of tests per week. The Elecsys Anti-SARS-CoV-2 antibody test received Emergency Use Authorization from the U.S. Food and Drug Administration earlier this month. 
"Roche is proud to make this highly accurate serology test available in the U.S. to determine if a person has developed antibodies to COVID-19," said Matt Sause, president and CEO of Roche Diagnostics North America. "Reliable, high-quality antibody testing is essential to help us overcome this pandemic and will play an important role in getting people back to work. We are proud to partner with LabCorp in making this test available in the U.S." 
The Roche antibody test is uniquely designed to identify mature (high affinity) antibodies developed late in the immune response, significantly reducing the chance of a false positive result. It provides 99.8 percent specificity, which is greater than previously available antibody tests. This specificity is crucial to determine reliably if a person has been exposed to the virus and has developed antibodies. Tests with lower specificity and sensitivity can lead to a high number of misidentified cases in a population. A false positive result may put a patient at risk by indicating they have antibodies when they do not.
"Our long-standing relationship and collaboration with Roche enables us to introduce many innovative, high-quality tests for clinicians and patients, which is more important now than ever before," said Dr. Brian Caveney, chief medical officer and president of LabCorp Diagnostics. "Roche's new antibody test allows LabCorp to provide more options and increase COVID-19 testing capacity as we support the country's response to the health crisis."
Roche has more than 3,000 analyzers that perform the antibody test installed across the United States. Roche is distributing millions of tests per week to U.S. labs that can implement quickly, enable the broadest geographic reach and provide testing to areas hardest hit by COVID-19. 
Roche is working to meet demand by scaling global production rapidly in an effort to expand broader access as quickly as possible.
Healthcare providers can order the test for patients through their normal clinical laboratory process. 
The Elecsys Anti-SARS-CoV-2 test, which is based on an in-solution double-antigen sandwich format, can detect antibodies to the new coronavirus causing COVID-19, which could signal whether a person has already been infected and potentially developed immunity to the virus. Based on the measurement of a total of 5,272 samples, the Elecsys Anti-SARS-CoV-2 assay has 99.8 percent specificity and shows no cross-reactivity to the common cold, HIV and other coronaviruses. This means it can lower the chance of false positives due to the detection of similar antibodies that may be present in an individual. Elecsys Anti-SARS-CoV-2 detected antibodies with 100 percent sensitivity in samples taken 14 days after a PCR-confirmed infection. As of April 24, no study has evaluated whether the presence of antibodies to SARS-CoV-2 confers immunity to subsequent infection by this virus in humans.
