RE:RE:RE:Stage websiteI think the reason for the new "add to cart" with a prescription included option is likely due to this:
"Unlike COVID-19 tests, cancer tests in the U.S. have to be prescribed by a physician. Therefore StageZero needed to find a way to reach patients with doctor support. The HC Companies acquisition immediately filled this requirement and more, as it provides an existing network of physicians as well as patients, a marketing group, and a 24/7 support team."
Before the test had to be prescribed by your own physician
