Hmm, this'll be tricky to figure out since I don't want you sharing screenshots with sensitive medical data, and I can't really test it since I don't have labs to check on Quest. When you get a lab report, is there a menu button? If so, is the only option there Email? Or is it a Share option?
Also, when you see the report, is it in PDF format? If so, what happens if you long-press it?
