So it turns out Mayo JAX did send it to Mayo MN. Mayo MN sent it out Monday afternoon. It arrived at Natera around 9PM PT / 11PM ET yesterday. I asked the RN why this is so convoluted and she told me Mayo will not change this. So this adds almost a week of unnecessary delay to the process. I did get an email and text message from Natera but this morning the test did not appear on the portal yet.
