Nephrocalcinosis may be discovered during tests performed for renal insufficiency, kidney failure, obstructive uropathy or formation of urinary tract stones.
Tests that may be done to confirm the diagnosis include:
Ultrasound to obtain images of the kidneys and the surrounding structures to detect any signs of damage
Abdominal CT (Computerized Tomography) scan in which a series of images are taken, using X-rays, to generate a three-dimensional image
Blood test to determine the levels of calcium, phosphate, uric acid and parathyroid hormone
Urinalysis to determine the acidity and levels of calcium, sodium, uric acid, oxalate, and citrate in the urine. You may be asked to collect your child’s urine samples over the period of twenty-four hours for an accurate result
