Urine K to Creatinine Ratio Calculator

Formula

To calculate the Urine K to Creatinine Ratio:

\[ \text{KCR} = \frac{K \times 1000}{\text{Cr} \times 88} \]

Where:

\(K\) is the urine potassium level (mmol/L)
\(\text{Cr}\) is the creatinine level (mmol/L)
1000 is the factor to convert potassium to milligrams
88 is the conversion factor for creatinine

What is the Urine K to Creatinine Ratio?

The Urine Potassium to Creatinine Ratio (KCR) is a measure used to assess the excretion of potassium relative to creatinine in urine. This ratio is used in clinical settings to evaluate kidney function and electrolyte balance. A higher or lower ratio may indicate different physiological or pathological conditions, depending on the context.

Example Calculation 1

Let's assume the following values:

Urine Potassium Level (K) = 20 mmol/L
Creatinine Level (Cr) = 1.2 mmol/L

Using the formula:

\[ \text{KCR} = \frac{20 \times 1000}{1.2 \times 88} \approx 18.94 \]

Urine K to Creatinine Ratio (KCR): 18.94

Example Calculation 2

Let's assume the following values:

Urine Potassium Level (K) = 30 mmol/L
Creatinine Level (Cr) = 2.5 mmol/L

Using the formula:

\[ \text{KCR} = \frac{30 \times 1000}{2.5 \times 88} \approx 136.36 \]

Urine K to Creatinine Ratio (KCR): 136.36
