Avero Diagnostics, a physician-owned laboratory, is expanding its covid-19 testing portfolio with the addition of the Roche Elecsys Anti-SARS-CoV-2 antibody test. Serological testing supports the Centers for Disease Control and Prevention (CDC) efforts to more accurately understand how many people have been infected with SARS-CoV-2, the virus that causes covid-19, and how it is spreading. This covid-19 serology testing offering, available now, will complement Avero’s existing covid-19 molecular testing program, which Avero launched in May 2020 to support the diagnostic needs of area hospitals, health systems, multi-specialty family practices, urgent care centers, and county health departments. “As the medical and scientific communities work to understand and stop the spread of covid-19, serological testing serves as a piece of the very complex puzzle,” says Trae Mattison, MD, managing partner, Avero Diagnostics. “By expanding our covid-19 testing services, we are not only supporting the need for serology testing in our community, we are also contributing to the national effort to understand the spread of the SARS-CoV-2 virus.” A serological test, often called antibody testing, is used to determine whether a person may have had a past infection with the virus that causes covid-19. This test uses a blood sample to provide qualitative detection of high-affinity antibodies to SARS-CoV-2, to aid in identifying individuals with an adaptive immune response to SARS-CoV-2, indicating recent or prior infection. This assay enriches detection of higher affinity antibodies which are more likely to be specific for SARS-CoV-2. While this assay in principle can detect antibodies of all isotypes (i.e., IgG, IgA, IgM), it preferentially detects IgG antibodies. This test is recommended for individuals 14 days post-symptom onset, or 5 to 7 days following exposure to individuals with confirmed covid-19. Avero Diagnostics’ CLIA-certified and CAP-accredited laboratory is using the Roche immunoassay for the qualitative detection of antibodies against SARS-CoV-2. The test is an electro-chemiluminescence immunoassay with 99.8% specificity. Avero can initially process approximately 800 tests per day, with the potential to scale up capacity based on demand. Avero expects to provide results to ordering providers within 24 to 48 hours. For more information, visit Avero Diagnostics.
