Pennsylvania Governor Wolf’s Administration began distribution of the 10th allotment of COVID-19 antigen test kits provided by the federal government to Clinical Laboratory Improvement Amendments (CLIA)-certified institutions in the remaining 20 counties that have not yet received a shipment. All 67 counties have now received shipment of antigen tests. The test detects an antigen on the surface of the SARS-CoV-2 virus while the Polymerase chain reaction (PCR) test detects viral RNA. Both PCR and antigen tests can detect active infection and are considered diagnostic tests. Antigen tests can be considered for symptomatic individuals (within the first five to seven days of symptom onset) and in asymptomatic individuals in settings where there is a high probability that the individual to be tested is positive, such as when they are a close contact of a case. On Oct. 15, the Secretary of Health issued an Order to health care providers and facilities reinforcing that all antigen test results, both positive and negative, are required to be reported to the Department of Health. If you have questions about tests, please contact Eric Kiehl, PACHC Director of Public Policy and Partnerships.
