Special lab set up and operating since Friday. Results available within 15 minutes for the antigen tests and 2 hours for the full PCR

Details and costs in the article.

$45-70 for testing at the airport.

I would still suggest doing the testing in town before heading to the airport if at all possible.

Not sure that in town it would be any cheaper. The guys at the airport are promising results in a short time frame....

It may not be cheaper but what happens if there are hundreds waiting for testing and you've "only" arrived half a day prior to flight time?

Indeed. Or what happens if they have a service disruptions/delays even for reasons unrelated to not being at the airport early enough. And there is also the issue of where would you rather be when finding out you're dealing with a positive test result (and then maybe want to get another test done to see if the results are consistent).

Having the airport testing option is great, but I would generally prefer to get the testing done in town and wait in town for the results before heading to the airport to catch a flight out of EZE.
