LabCorp said on Thursday it has launched a new test that could assess the capacity of antibodies in patient plasma to inhibit the novel coronavirus.
Information from the test about the virus-fighting ability of antibodies could be used in the development of Covid-19 vaccines, the company said.
The test, called the neutralizing antibody test, would be available to biopharmaceutical companies, hospitals, blood banks and other blood plasma-screening facilities.
Neutralizing antibodies are associated with protective immunity against re-infection for many infectious pathogens, according to the Mayo Clinic.
The test could be used in screening serum collected from recovered Covid-19 patients for preventive and therapeutic use, the company said.
The company made its Covid-19 tests available at workplaces last month and it also provides lab tests and antibody blood tests that can tell whether a person has ever been infected, as well as kits that allow people to mail in their own nasal swab samples collected at home.
