I have had a similar problem with the lab fax not getting to Mayo. I found out that the main lab holds the results and they go out the following day or when they get a batch. I have had to go to the main building and trek to the records department to have them sent again while I wait for a “received” response on the fax. The lab has told me too many times that the problem has to be at Mayo’s end. (I don’t do the blame game very well 🤨). Once I discovered that they were faxing to wrong address using a similar area code!
As a result I always return to the free standing lab building and pick up my results, just to check if sent to correct address. Luckily I’m now on a 3 month schedule. I used to copy and fax like you, but that got old real quickly. I even scanned and sent a copy via patient portal, but have been told not to do it that way because of an updated lab filing system that is not connected there.
So I think I have found a solution! It was the idea of the sweet nurse at the lab! She faxes it right there when I pick up my hard copy …and Mayo has it posted on my portal by the end of the day😃

Recently I got a notice that Mayo Rochester was using Quest because they arranged to connect electronically. I see some members are able to do it that way. However, I don’t have a Quest lab nearby.

I’m due for labs in a few weeks. I hopeful that my latest solution works, again. I’l let you know, and it might be something that could work for you 🤞
