When in pharmacies will there be tests for coronavirus, which the patient can independently perform at home?

When will these tests be available in pharmacies? I want to be able to check if my symptoms are the result of allergies (I am allergic) or whether they are symptoms of the disease. If we are to combat COVID, this test should appear in pharmacies for home use. Any wise and responsible person after seeing a positive result if he works differently than remotely will perform a test at the doctor's command, while the others can prescribe themselves a guarantee.
