My 13 yr old daughter has had anoreixia and high presence of protein in urine for the past 3 years. Evry single urine test done shows high level of protein in urine, even the first morning samples. She had a series of complicated blood tests and ultrasound done a couple years ago, which all came back normal. But since the protenuria continues to be a concern, the nephrologist wants her to undergo more tests at this time, also suggesting a renal biopsy. She has no signs or symptoms, other than the proteinuria.
What are we to do? And what do we expect? We are distraught. Please advise. Thank you
