I don't think the travel agency is screening the test in their office. Looks like they do the swabs and send out for analysis and results to Pathcare. If I could go direct to Pathcare to be tested I would probably get results on the spot, within the 15 minutes. Pathcare only does testing in the mornings and they do not do fast antigen testing from what I see on their web site. Again, this could change over the next few months before my trip in May.
