Major League Baseball employees, including players, will take part in the first and largest COVID-19 antibody test in the United States.
The effort will determine who has already been exposed to the disease caused by the novel coronavirus and may have developed some level of immunity.
An MLB spokesman confirmed that the 10,000 league employees including players, volunteered to take part in the study, which was first reported by The Athletic. The outlet added that 27 of the 30 teams will be participating. All volunteers will submit their results anonymously.
The test, called the COVID-19 Sero Pervalence Study, is being conducted by researchers from Stanford, USC and the Sports Medicine Research and Testing Laboratory.
