My son passed ADOS twice out of three times he was tested (he was diagnosed at 2.5 with PDD-NOS based on ADOS but lost it twice later based on ADOS at 4.5 and 6.5).
So I am not a fan of ADOS as you understand. You either have ASD or you don't, and they've been messing with my head regarding that for the last five years (my son is 7.5y now). My son is caught in the middle between neurotypicals and not so much.
So if she is mild, ADOS is a waste of time in my opinion.
I would focus on depression most of all.
