IRVINE, Calif. (KABC) -- A new antibody test that researchers say may be the most comprehensive in California is coming to Orange County.

Researchers from UC Irvine plan to examine the blood of 5,000 people for antibodies to the coronavirus.

Unlike similar testing in Los Angeles and Santa Clara counties, researchers say this test involves many more people.

There will be eight to 10 drive-through sites. A pinprick will be used on county residents picked for the study and samples will be sent to UCI to be analyzed.

The study seeks to find out how widespread COVID-19 is in the county and health officials plan to use the data to guide them with public health measures.

Results will also be used to better identify at-risk populations.
