I am sorry for posting so many questions. I am getting ready to meet with my daughter’s endocrinologist next week and I am compiling my list to review with him. I was interested in that 24 hour urine test. I wanted to know how it worked. Do you stay at the hospital or collect this at home, or what do you do? I am striving for accurate readings of my daughter’s levels. I have always strived for that but now that she is approaching puberty I want a close to perfect reading to keep an eye on her progress. We get a bone age done today along with bloodwork. Thank you!Laura
