"Vera Ivanovna, are you well?"
Translation:Вера Ивановна, у вас всё хорошо?
Folks from older generations may still call each other "ты" while using the patronymics. Nevertheless, the use of "вы" would be significantly more likely in such situations. Both express certain degree of respect and they go well together.
And then, as Arthur has already mentioned, you need to use the genitive case with the proposition "у" here: "у вас/у тебя". This is how the language works.
