Fractional Excretion of Urea (FEUrea) Calculator
The Fractional Excretion of Urea Calculator is a medical tool used to assess kidney function.
The Fractional Excretion of Urea (FEUrea) Calculator is a medical tool used to assess kidney function. This calculator helps to evaluate kidney function by calculating the rate of absorption and excretion of urea in urine by the kidneys. The FEUrea value provides information on the reabsorption of urea in urine by the kidneys and indicates the ability of the kidneys to make urine. This calculator is used in clinical settings to diagnose and monitor kidney diseases. Using the Fractional Excretion of Urea (FEUrea) Calculator helps healthcare professionals in accurate assessments.
When using the online Fractional Excretion of Urea (FEUrea) Calculator, you can calculate by entering: BUN, Creatinine, Urine Urea, and Urine Creatinine.
FEU_{rea} = \left(\frac{UUN \cdot Cr_S}{BUN \cdot Cr_U}\right) \times 100

Understanding the Fractional Excretion of Urea (FEUrea) Calculator: How it Works
Fractional Excretion of Urea (FEUrea) is a parameter used to assess kidney function. This value reflects the rate of absorption and excretion of urea in urine by the kidneys. FEUrea is usually expressed as a percentage (%) and indicates how urea is processed by the kidneys. This parameter plays an important role in clinical situations such as assessment of kidney function, diagnosis, and monitoring of kidney diseases. The Fractional Excretion of Urea (FEUrea) Calculator simplifies this process.
How is Fractional Excretion of Urea Calculated Using the Fractional Excretion of Urea (FEUrea) Calculator?
Fractional Excretion of Urea (FEUrea) is a ratio that helps assess the capacity of the kidneys to create and excrete urine. Normally, the FEUrea ratio should be within a certain range, but this value may vary depending on the clinical situation, laboratory norms, and patient characteristics. Therefore, the FEUrea value is usually interpreted in combination with clinical assessment and other renal function test results. This parameter is used during the diagnosis and monitoring of kidney diseases, and the Fractional Excretion of Urea (FEUrea) Calculator aids in this interpretation.
Urinary Excretion of Urea and the Role of the Fractional Excretion of Urea (FEUrea) Calculator
Urinary excretion of urea is the process of removing some of the nitrogen in the body through the kidneys. This process is important for maintaining nitrogen balance in the body and removing metabolic waste products. Urea is a waste product of protein metabolism and is synthesized in the liver as urea. It is then filtered by the kidneys and excreted in the urine.
FEUrea stands for Fractional Excretion of Urea and is a parameter that helps assess the kidneys’ ability to absorb and excrete urea. It indicates how much of the urea in the urine is filtered and reabsorbed by the kidneys from the blood. The role of FEUrea, especially when calculated using the Fractional Excretion of Urea (FEUrea) Calculator, is to assess kidney function and serve as an indicator used in the diagnosis and treatment of kidney diseases. Therefore, the correct calculation and interpretation of FEUrea is important in monitoring kidney function and establishing treatment plans.
Interpretation of FEUrea Values from the Fractional Excretion of Urea (FEUrea) Calculator
FEUrea values, as calculated by the Fractional Excretion of Urea (FEUrea) Calculator, are a parameter used to assess kidney function and are usually expressed as a percentage (%). Interpretation of these values is important to understand kidney function and to assess kidney disease. The interpretation of FEUrea values can be done as follows:
- Normal Range: Usually, healthy individuals have an FEUrea value between 35% and 50%. This range reflects normal kidney function and indicates proper excretion of urea.
- Low Values: A lower than normal FEUrea value may indicate that the level of urea in the blood is low and the kidneys are increasing the absorption of urea. This may indicate decreased kidney function or increased kidney absorption of urea.
- High Values: A FEUrea value above normal may indicate that the level of urea in the blood is high and that the kidneys are increasing urea excretion. This may indicate increased kidney function or increased renal excretion of urea.
The interpretation of FEUrea values, especially when derived from the Fractional Excretion of Urea (FEUrea) Calculator, is usually considered in conjunction with other clinical findings and renal function test results. Deviation of these values from normal may indicate the presence of renal diseases or changes in renal function and may help to determine appropriate treatment and management strategies. Therefore, it is important that FEUrea values are interpreted carefully and considered in the clinical context. You can also find more calculation tools on our Calculation Tools page.
Uses of the Fractional Excretion of Urea (FEUrea) Calculator and Test
The FEUrea test, and consequently the Fractional Excretion of Urea (FEUrea) Calculator, is a laboratory test used to assess renal function and can be used in the diagnosis and monitoring of various clinical conditions. Common uses of the FEUrea test are as follows:
- Assessment of Kidney Function: The FEUrea test, and the Fractional Excretion of Urea (FEUrea) Calculator, is used to determine the rate of urea absorption and excretion by the kidneys. This helps to assess kidney function and is important to determine whether the kidneys are functioning normally or abnormally.
- Diagnosis of Kidney Diseases: The FEUrea test, and the Fractional Excretion of Urea (FEUrea) Calculator, can help in the diagnosis and classification of kidney diseases. In particular, determining changes in the kidneys’ absorption and excretion of urea is important for early diagnosis and treatment of kidney diseases.
- Monitoring Other Medical Conditions: The FEUrea test, and the Fractional Excretion of Urea (FEUrea) Calculator, can be used in a variety of medical conditions where kidney function needs to be monitored, in particular kidney failure, kidney stones, hypertension, diabetes, and liver diseases.
- Evaluation of Kidney Function Response to Treatment: The FEUrea test, and the Fractional Excretion of Urea (FEUrea) Calculator, can also be used to evaluate the treatment response of kidney diseases. Changes in FEUrea values during treatment may be important for assessing response to treatment and adjusting the treatment plan.
Although the FEUrea test and the Fractional Excretion of Urea (FEUrea) Calculator are important tools for assessing renal function, the results need to be evaluated in conjunction with other clinical findings and test results. This helps to make an accurate diagnosis and establish appropriate treatment plans.
