Biomarkers of Renal Dysfunction in Neuroblastoma Survivors

Biomarkers of Renal Dysfunction in Neuroblastoma Survivors

The main purpose of this study is to learn more about biomarkers of kidney function in the blood and urine of neuroblastoma survivors. A biomarker is a biological molecule found in blood, urine, other body fluids, or tissues that is a sign of a normal or abnormal process, or of a condition or disease. A biomarker may be used to see how well the body responds to a treatment for a disease or condition.
