Walgreens Increasing Covid-19 Testing Capacity WASHINGTON (dpa-AFX) - Drugstore chain Walgreens, and healthcare company Aegis Sciences Corp. are extending their relationship to perform fast and accurate COVID-19 diagnostic testing as Walgreens further expands COVID-19 drive-thru testing nationwide. The drive-thru locations are part of Walgreens' collaboration with the administration, federal health agencies, as well as state and local authorities for COVID-19 testing. Walgreens activated its first drive-thru testing site in the Chicago area on March 21, 2020. The companies are looking to boost the testing services across more than 3,000 Walgreens pharmacy locations in February by providing additional testing capacity with good turnaround times. They are also planning to further increase the testing over the next few months.
