A few weeks ago we reported that Ortho Clinical Diagnostics had seen its COVID-19 total antibody test CE marked. Now the in vitro diagnostics company tells us its second COVID-19 antibody test—the VITROS® Immunodiagnostic Products Anti-SARS-CoV-2 IgG Test (COVID-19 IgG antibody test) has also received European accreditation. The test offers 100% specificity.
Background
Ortho’s COVID-19 IgG antibody test detects the IgG antibody. It closely follows the introduction of Ortho’s COVID-19 Total test and the two tests offer greater choice in tracking and surveillance, patient management, and screening convalescent plasma. Both of Ortho’s tests help health care professionals understand if a patient has been exposed to and has developed antibodies to the SARS-CoV-2 virus.
Ortho’s COVID-19 IgG antibody test received Emergency Use Authorization from the U.S. Food and Drug FDA administration on April 24, 2020. Ortho’s total antibody test received CE Mark on May 8, 2020 and FDA Emergency Use Authorization on April 14, 2020.
The tests run on Ortho’s high-throughput, fully automated analyzers including its flagship VITROS® XT 7600 Integrated System, the VITROS® 3600 Immunodiagnostic System, the VITROS® 5600 Integrated System and will soon be available on VITROS® ECi/ECiQ Immunodiagnostic Systems. Ortho has over 5,600 Immunodiagnostic systems installed around the world. VITROS Systems are self-contained and do not require an external water source to run, offering labs placement flexibility.
Ortho is manufacturing the COVID-19 IgG antibody tests at its Pencoed, U.K., facility. It plans to manufacture several million tests in the coming weeks.
Ortho’s COVID-19 IgG antibody tests are designed and solely intended to be performed by laboratory professionals and cannot be directly used by patients as they are not for home use. Patients should consult with their health care provider to discuss antibody testing and back-to-work options.
Clinician comments
“The observed 100% specificity with Ortho’s VITROS SARS-CoV-2 tests allows an extremely high level of confidence so that people will not be identified as having an immune response to the virus when in fact they do not,” said Christopher D. Hillyer, MD, President and CEO, New York Blood Center. “Statistically, the chance of error rises dramatically even with a very small decline from 100% in specificity, given our understanding of the prevalence of the COVID-19 virus today.”
Company comments
“Ortho is proud that both of our COVID-19 total and IgG tests are achieving 100% specificity,” said Chris Smith, Ortho Clinical Diagnostics’ Chief Executive Officer. “During this health crisis, good is simply not good enough. This high level of specificity is a testament to Ortho’s strong belief that every test is a life.”
