This test is mostly useless anyway: you need to administer it at the narrow window when you have covid for it to be effective. This implies that you have to keep it on hand, ie it can be too late to order it when you have symptoms since it can be delivered too late to detect anything. Then you have to wait for results for many days once you send it - so it’s useless for guiding your action during the time you have symptoms. If you administer the test when you don’t have symptoms it useless as well since most likely you will miss the window.
