Does the Rapid Antigen test given at Madrid Airport work to get you back to the US?
What types of SARS-CoV-2 test are acceptable under the Order?
Passengers must be tested with a viral test that could be either an antigen test or a nucleic acid amplification test (NAAT). Examples of available NAATs for SARS-CoV-2 include but are not restricted to reverse transcription polymerase chain reaction (RT-PCR), reverse transcription loop-mediated isothermal amplification (RT-LAMP), transcription-mediated amplification (TMA), nicking enzyme amplification reaction (NEAR), and helicase-dependent amplification (HDA). The test used must be authorized for use by the relevant national authority for the detection of SARS-CoV-2 in the country where the test is administered. A viral test conducted for U.S. Department of Defense (DOD) personnel, including DOD contractors, dependents, and other U.S. government employees, and tested by a DOD laboratory located in a foreign country also meets the requirements of the Order.

It worked for me when I returned to the USA from Spain at the end of July.
Yes, the rapid antigen test is fine, I used it this morning and I’m seating at my gate to board my plane home to USA.
IMPORTANT!!
You need to schedule the test online at the site your getting tested before you actually go there. We saw people turned away at the airport because they thought they could just walk up and get it that morning. We got our results in 15 min, they e-mail you official form that states your negative.
