“Premier Biotech, the lab which makes the tests, says on its website that the results are available within 10 minutes of the sample being taken and that the results remain valid for 20 minutes.”
1. I think you mean results are available within 10 minutes of start of test.
2. Test results don’t expire.
One of the comments made by a member of the study team from another article on the same subject at ‘The Stanford Daily’ stated results were expected on Sunday evening April 5th and she did not know why the delay.
Her emails asking why had not been returned.
If you have any other questions feel free to ask google.
