A tactic I use, spino, is to insist (without having experienced any overt pushback so far) that the pre-visit blood work results be available to me minimally a day or two before the scheduled 3-month/6-month visits, rather than the blood draw and results only on visit day and the results first presented to me at the visit. In this way, I am able to prepare questions about those current results beforehand. (Obviously, this requires my being available for the blood draw in advance, which not all may be able to do.)
