Ditto with the previous messages. It is critical that your daughter's levels be tested. My son's endo (and I suspect everyone's) is also difficult to get a scheduled appt. with. But you don't necessarily need a dr. appt to draw the blood. It can be done by a lab tech or nurse with the results phoned or faxed to the dr. It would only take the dr. a few minutes to review the results and call you. That said, how can any dr. say a few minutes of their time is not worth the life of your child. As many previous "posters" have reminded me. You are your child's only advocate. Good luck!
