Enter your numbers, get your report, follow the treatment guidelines.
Always get a copy of your labs, not just your doctor's interpretation of them. I've seen doctors tell patients they were fine, only to see that their actual labs showed significant anemia.
Keep your own medical file at home so that you can easily switch practitioners at any time and not have to worry about going to each of your previous practitioners and having them send your records to your new person. This will save you $$, time, and possibly a lot of hassle.
