Estimate GFR in Children



Formula

The formula to estimate the Glomerular Filtration Rate (GFR) in children is:

\[ eGFR = \frac{k \times \text{Height}}{\text{Serum Creatinine}} \]

What is the Schwartz Formula?

The Schwartz formula is a simple and widely used method to estimate the kidney function in children. It is particularly useful because it accounts for the growth of the child, providing a more accurate assessment of kidney function than serum creatinine alone. The formula is named after Dr. Schwartz, who developed it in 1976.

Example Calculation

Let's assume the following values:

Using the formula:

\[ eGFR = \frac{0.413 \times 120}{0.8} \approx 61.95 \, \text{mL/min/1.73 m²} \]

The estimated GFR is approximately 61.95 mL/min/1.73 m².
