Kidney Tests

If the pediatric nephrologists at RMHC at P/SL suspect your child may be suffering from a kidney disease, some diagnostic tests may be ordered.

First, your child’s pediatric nephrologist will perform a physical exam and take a medical history. Then, as needed, one or more of the following tests may be ordered:

  • Computed tomography (CT or CAT) scan - a procedure using x-rays and computer technology to show a detailed image of the body
  • Kidney biopsy - after removing a small piece of kidney tissue with a needle, tests are performed to determine what type of kidney disorder may be present
  • Renal nuclear scan - a small, safe amount of radioactive material is injected into the vein and a scan is taken giving a clear picture of the shape, size and function of the kidneys
  • Ultrasound (sonography) - a test that uses sound waves and computer technology to create pictures of the organs, tissues and blood vessels
  • Urinalysis - a laboratory test done on a sample of your child’s urine
  • Voiding cystourethrogram (VCUG) - a dye is placed into the bladder and observed to determine if there is something blocking the flow in the system or if there is a reflux of urine from the bladder into the kidneys where the urine goes backward in the system
  • X-ray - a test that uses electromagnetic energy beams to create images
