My oncology colleagues don't give a hoot about PDL1 testing in the clinical setting. They've got some clinical trials going, but otherwise we're not hassled with that nonsense.
As for QNS testing, it's mostly a problem with the EBUS specimens in our experience. We go on the FNA for adequacy checks and I flat out say this likely isn't enough for molecular testing. Invariably the IR guys will be asked to needle it and it's usually enough. I ask for 6 good 1 cm cores unless I see a lot of necrosis on the adequacy TP. I have the tech then gross each core into its own cassette so we can separate it out better and not lose limited specimen each time the block gets used/faced for additional testing. This works out pretty well for us whether it's simple PCR testing, Foundation One, Paradigm, etc.
