Similarly with RATs, there is a cost associated with it and it's not all that practical time wise considering you have to source the product (can be difficult), take the time to administer it and still need a PCR test to confirm. Resapp at least will be on hand, offer a similar if not better diagnosis and reduce the need for further testing. If I have my shark tank hat on, any product I can deliver to the customer with limited effort on their part using a tool they already have, is an enticing prospect.
