I was just approved yesterday and we had no source listed on our test either.
Same here, two different test dates and both reports were exactly like The_Lurker's...no acceptance issues. A PCR is a PCR....not gonna be taken from your armpit
Your April results are an example of the discretion/judgement used by the reviewers, but also that info being missing is a very simple reason for denial.
...and using a test (home BinaxNow with telemed) that is listed as not acceptable has a greater chance of denial. I will stick with the PCR but everyone has their own choice to make
