If you have a Walgreens or Urgent Care office near you that is using the IDNow test, that test is a PCR test that is accepted by EHAS and the results are usually returned in 30 minutes to 2 hours( IDNow is a rapid PCR test). This test qualifies for the 48 hour submission.

The rapid Antigen test is offered in many places CVS, Walgreens, state testing sites etc and those tests usually give results in less than 30 minutes. These test qualify under the 24 hour submission.

Both of the solutions above should allow for plenty of time to get your results and submit to EHAS and get your pre-approval. Scheduling is important, don't schedule test at 6pm when you are scheduled to fly the next morning at 9am.

Both Walgreens and CVS will give you results that meet the requirements of EHAS. I recommend printing out a hard copy and saving a digital copy of the PDF results on your phone.

I hope this helps and any clarifications just ask.
