I would be happy to assist you with your question.
There are many different reasons protein may be found in urine. If your child has an urinary tract infection, then yes indeed, it is most likely the cause of proteinuria. It is also possible that her kidneys are inflamed due to the infection which is a leading cause of protien in the urine. Your child should be administered medication which I am assuming her doctor prescribed. After she is finished with her antibioitcs, she should once again have another urine sample. If the protein level is still high, then further investigation should be done. Protein in urine is often a sign of damaged kidneys, or beginning kidney failure if no infection is present and high levels are found. High levels are generally considered above 150. A normal person can excrete up to 150 mg of protein daily, ad be considered healthy. Your daughters lab levels are not unusual, especially with an infection present, and there is likely no reason to worry.
