The company’s blood-based immunoassay can help clinicians determine whether an individual has developed antibodies against SARS-CoV-2. Clinical evaluation of the test has demonstrated diagnostic specificity of more than 99% and sensitivity of 98%. Crossreactivity testing demonstrated specificity of 100%, with no reactivity against other interfering substances, including non-SARS-CoV-2 coronaviruses.

“We are pleased to have received FDA emergency use authorization for our SARS-CoV-2 total antibody test to support covid-19 diagnosis,” says Dara Wright, executive vice president of Bio-Rad Laboratories and president of the company’s clinical diagnostics group. “The total antibody approach enables detection of antibodies in the majority of patients 8 days after the onset of symptoms, versus an IgG-only approach.”

Bio-Rad’s SARS-CoV-2 total antibody test can be performed manually or on an automated immunoassay platform such as Bio-Rad’s Evolis system, which offers high-throughput processing and sample traceability.
