Abbott Laboratories' BinaxNOW coronavirus self-test kits will be shipped to CVS Pharmacy, Walgreens and Walmart locations and also will be sold online. The two-test kit, which last month received FDA emergency-use authorization for serial screening, will cost $23.99, the company said. Another rapid test made by Australia-based Ellume will be sold at CVS stores in Rhode Island and Massachusetts for $38.99. It also can be purchased online or at most CVS stores in other states by the end of May. These retail tests eliminate another barrier for people who want to test themselves without visiting a doctor or a telehealth provider. Both tests deliver results in about 15 minutes and don't require a lab.
