CalScope Logo

CalScope is a population-based seroprevalence study that will help the California Department of Public Health (CDPH) learn how many Californians have antibodies to SARS-CoV-2, the virus that causes COVID-19. A person may have antibodies in their blood due to a past infection or vaccination. This information will help CDPH understand COVID-19 disease burden and design more effective and efficient mitigation strategies.

CalScope BoxThrough CalScope, households in selected counties are randomly invited to take a brief, anonymous survey and a free, at-home COVID-19 antibody test (using a finger-prick blood sample).

Up to one adult and one child from an invited household can participate and are eligible to receive up to $40 in gift cards per participant. The CalScope study is taking place in three separate waves during 2021-2022.

Local public agencies and community partners can help invited participants learn more about CalScope and encourage them to participate.
