PCR lab tests (not rapid antigen tests) for COVID

Thanks Sue. I phoned Laboratorio Siena in Marfil at 473-102-7354,‬ and confirmed they do the PCR test for 1800 pesos. It's 100 pesos more if you request them to do the swab on a house call.
The website says they report the result in 24 hours, but it appears if might take 30 hours from the time the sample is collected. In any event, this is the most sensitive and accurate test available.
