HPV + NavDx blood test for circulating tumor DNA

Found out about this test here by chance while combing through threads and posts in the H & N support group.
I think it deserves its own thread where current and future patients with this particular cancer might find it more easily.
Its only been around a few years but is an excellent surveillance tool .
Covered by Medicare , the VA and possibly other insurers.
Its a little pricey out of pocket .
Vets will need prior authorization which can take 2-3 weeks so plan ahead.
Here is a link to the company that provides it with all the info about it.
