FEUrea Urine Calculator FENa

**FEUrea Calculator – Fractional Excretion of Urea**

FEUrea Calculator is a fast and easy medical calculator for **FEUrea (Fractional Excretion of Urea)** and kidney function assessment. Calculate **fractional urea excretion** using urine urea, serum urea, urine creatinine, and serum creatinine values.

### FEUrea Calculator

**FEUrea (Fractional Excretion of Urea)** estimates the percentage of filtered urea that is excreted by the kidneys. The FEUrea calculation can provide useful information about **renal function, kidney urea handling, and urinary urea excretion**.

Calculate FEUrea using four laboratory values:

• Urine urea
• Serum urea
• Urine creatinine
• Serum creatinine

Enter the required laboratory results and get the **FEUrea result** instantly.

The **fractional excretion of urea** is an important renal calculation used when evaluating kidney function and interpreting urine and blood laboratory results. FEUrea may be considered during assessment of **acute kidney injury (AKI), renal dysfunction, and changes in kidney function**.

### FEUrea & Kidney Function

The FEUrea calculator is designed for quick **fractional urea excretion calculations** in clinical practice, bedside reference, medical education, and study. It can help doctors, medical students, nurses, healthcare professionals, and students studying **renal physiology, kidney function, urea handling, and urine laboratory values**.

Use FEUrea together with the patient's clinical presentation, laboratory findings, urine studies, and other relevant information. FEUrea is a calculated value and should not be used as a standalone diagnostic test.

### Why Use the FEUrea Calculator?

• Fast **FEUrea calculation**
• Calculate **fractional excretion of urea**
• Uses urine urea and serum urea
• Uses urine creatinine and serum creatinine
• Useful for **kidney and renal function assessment**
• Helpful for studying renal physiology
• Useful in evaluation of kidney-related laboratory results
• Simple and convenient interface

### FENa Calculator

The app also includes **FENa (Fractional Excretion of Sodium)**. Calculate fractional sodium excretion using urine sodium, serum sodium, urine creatinine, and serum creatinine. FENa provides an additional measure of renal sodium handling and can be considered alongside FEUrea when assessing kidney function and acute kidney injury.

### BUN/Creatinine Ratio Calculator

Calculate the **BUN creatinine ratio** using blood urea nitrogen (BUN) and serum creatinine values. The BUN/creatinine ratio provides an additional calculation for interpreting blood laboratory results and evaluating kidney-related findings.

### Albumin/Creatinine Ratio Calculator

Calculate the **albumin creatinine ratio (ACR)** using urine albumin and urine creatinine. The albumin/creatinine ratio is commonly used to assess urinary albumin excretion and support evaluation of kidney health.

### Kidney & Renal Calculators

The app includes:

• **FEUrea – Fractional Excretion of Urea**
• **FENa – Fractional Excretion of Sodium**
• **BUN/Creatinine Ratio**
• **Albumin/Creatinine Ratio (ACR)**

**FEUrea is the primary calculator in this app**, with additional kidney and renal laboratory calculations available for convenience.

This app is intended for **medical calculation and educational purposes**. It does not provide a diagnosis and does not replace professional medical judgment.
