Question
Why does protein appear in an infant’s urine?
Answer
Under normal circumstances, there should not be protein in an infant’s urine. Protein is an important nutrient in the body and is usually not filtered into urine through the kidney’s filtration system. When protein appears in the urine, it may be a sign of abnormal or damaged kidney filtration function. Proteinuria can be associated with various factors, including infection, kidney disease, or other health issues.
