CVS is limiting the number of at-home coronavirus tests customers can buy amid surges of the Delta variant across the US.
Originally having been able to purchase an unlimited number of tests, customers are now only allowed to purchase a maximum of six at a time from the CVS website or four at a time while shopping in-store, according to an email sent Friday from a CVS spokesperson. The tests are still available without a prescription.
The purchasing restraint is caused by manufacturing delays from suppliers of the tests. The limited tests include the Abbott BinaxNOW and Ellume at-home tests, the CVS spokesperson told Insider.
The delays are caused in part by fewer workers and slower production lines, a spokesperson from Abbott Laboratories told The Wall Street Journal. Ellume is experiencing similar issues, telling Bloomberg they are "scaling production and working with retailers to ensure consumer access to its tests."
Both Abbott Laboratories and Ellume did not respond to Insider's request for comment.
CVS cites "high demand" as a reason for the shortage of the tests. Demands for testing have grown as people return to school or the office this fall.
"We're continuing to work with our suppliers to meet customer demand," a CVS spokesperson said.
As coronavirus continues to spread, at-home testing is a popular option for those looking for quick results. The Delta variant is now responsible for most of the cases in the US and spreads faster and more easily than the earlier-detected versions of the coronavirus.
