thank you for this article. My daughter is having alot of blood drawn lately and today she had the limit for one day. I was told to wait at least 3 days before getting teh rest of the studies ordered done, but its good to know about hte monthly limits,as she has several docs requesting tests. She is 12 months old and is dropping weight so soemtimes the doctors order labs to be completed in a week and she drops weight so they can't do everything ordered when we get to the lab. I know understand the limits so much better.
