The California Department of Social Services (CDSS) has issued a Provider Information Notice (PIN) to provide guidance on the use of antigen tests, specifically the Abbott BinaxNOW™ COVID-19 Ag Card test kit, for adult and senior care program licensees. The PIN updates previous guidance on COVID-19 testing in care facilities by including viral antigen tests as an alternative to PCR tests. Antigen tests may be used for symptomatic and asymptomatic individuals and for screening purposes. However, the accuracy limitations of antigen testing must be considered, as they are not as accurate as PCR tests. Confirmatory PCR tests may be required within 48 hours of antigen testing, depending on the individual's symptoms and exposure. Facilities must be aware of the test kit's precautions and limitations and comply with training and test reporting requirements.
