Glad you asked. A short survey brought these results: The H+ Hospital charges 5,500 pesos, (aprox $275.00usd) it takes up to 48 hours for the results that are emailed to you. St Luke’s hospital does testing Mon-Thur 8-11am. It takes three days to get the results, and they charge $1,800 USD. Yes $$ not pesos. Hospital San Jose does a quick test for the antibodies, the results are in less than an hour. The cost is $44.99 USD. They also offer a PCR test, this test is $537.99 USD. You’re welcome!
