To test if putting the samples in the sky disrupted them, the researchers took a total of 336 samples from 56 patients. All of these samples were brought out to a field. Half of them were put in a drone and flown around for 6-38 minutes, while the other half stayed stationary. The researchers then brought all the samples to the lab, where technicians performed 33 of the most common tests on the samples. They found that flying didn’t make a significant difference, no matter how long they were in the air, though the tests done on the drone-transported samples were a bit less precise.
