Jon, when doing the batch signoff, you are given the option whether it will apply to labs as well. However, I don't know if you have to associate them to the patient first, which is 3/4 of the effort.
Neil, I agree that it seems I have to tell AC the same thing 3 times to import and signoff the lab... one mouse click should suffice. But remember... you will probably be getting maybe 6-10 labs a day tops, and it just doesn't take that long. My main gripe is that when you hit Import -> lab and x-ray, the import is painfully slow, and it totally ties up the computer on which you do the import. You cannot do e-mail, UpDox, or anything else while the import is happening. Our 4 provider practice gets usually about 6-7 labs a day, and I have to do something not requiring the computer for several minutes if I am the one clicking the button.
