Antigen test at airport

How much is it now. Where is it located. What do you need to show and how much time does it take for a late afternoon flight.
gracias.

We've had two recent trips to the States family emergency and recent planned event). Two months ago we had our antigen testing done at GDL before our flight to the States, the cost is $450 MX; time in line 30 mins; time for results about 40 mins (you can wait and pick-up hard copy and/or wait for email results); location on the third level of the parking garage (under cover) clean, organized, efficient set-up.

Recently we went to the the testing facility in Soriana parking lot. Pay in the Soriana Pharmacy FIRST $489 MX. We went about 11:00am, no line, efficient, clean, organized, results were by email-only and took about 90 mins+. Would do it again.
