That makes sense. I don't know if you're expecting customers to find a doc that will be willing to order or if you're curating a list of docs that customers can select from, but in my experience the latter is much simpler to navigate.
My wife was in a situation where she was in the ragged edges of a common disease that made her eligibility for various trials and therapies suspect. She had a somatic mutation that would be nice to be able to fully catalog. There is a trial going on right now (MATCH [0]) that does selective testing for mutations and deficiencies in cancer patients that have some associated trial therapy. This is fine but outcomes are of course going to vary and developing a catalog that can be mined after the fact might help identify other areas to focus on.
Best of luck to you and your company!
