What is the Fry Formula?

The Fry formula is a method used to estimate kidney function, specifically the glomerular filtration rate (GFR). It takes into account a person’s age, weight, and serum creatinine levels. The Fry score is particularly useful in clinical settings to adjust medication dosages and to monitor the progression of kidney disease.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ \text{Fry Score} = \left( \frac{150}{72 \times 1.2} \right) \times (140 - 45) = 164.93 \]

The Fry score is 164.93.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ \text{Fry Score} = \left( \frac{180}{72 \times 1.5} \right) \times (140 - 60) = 133.33 \]

The Fry score is 133.33.
