Improving the understanding, detection, and management of kidney disease.

Considerations for Pediatric Patients

Because routine urinalysis is no longer recommended as part of routine pediatric care, some children who would benefit from a urinalysis may not undergo this simple test. As a result, some children with kidney disease may go undetected or not receive appropriate follow-up.

Q & As on Using Urinalysis to Screen for Kidney Disease in Pediatric Patients

Who needs urinalysis as part of well child care?

Urinalysis is important for pediatric patients who have one or more of the following risk factors for chronic kidney disease (CKD).

These conditions are associated with cumulative kidney damage.

Why is it important to screen pediatric patients for CKD?

A majority of diseases that cause kidney failure and related cardiovascular complications among adults have their origins in childhood. Early detection and appropriate treatment may:

What tests should be used to screen for CKD?

Urine and blood tests are used to detect CKD. Begin with a standard urine dipstick. If the dipstick is positive for albumin, confirm the presence of albumin by performing a second dipstick on the first morning void, at least one or two weeks later.

For patients with two or more positive urine dipsticks completed one to two weeks apart, obtain two additional tests:

How is GFR estimated in children?

A child's GFR can be estimated using the Bedside IDMS-Traceable Schwartz equation. To perform the calculation, you will need the patient's serum creatinine level and height.

Bedside IDMS-traceable Schwartz GFR calculator for children

(for use with enzymatic creatinine methods that have been calibrated to be traceable to IDMS)

GFR (mL/min/1.73 m2) = (0.41 × Height) / Serum creatinine

What preventive strategies are recommended for children at risk for CKD when results do not indicate CKD?

Advise patients who are at increased risk for CKD to follow a program of risk reduction:

When should patients be referred to a pediatric nephrologist?

Refer to a nephrologist when the patient presents with one or more of the following conditions:
