Before I arrived I had two covid test. One email, one stamped. From two different places. I needed to be sure results came back in time. The one I had stamped the same doctor stamped the 2 fit,2fly I gave them. So I showed them the stamped one. But I always mention when giving them all my paperworthat I had 2 covid test with me. The stamped one had very basic information. My name, that I had be test for covid and results negative. Doctors office and a sticky receipt on the paper with the lab times and test. The emailed one was really detailed but no stamp.
