What is eGFR (estimated Glomerular Filtration Rate)?

eGFR, or estimated Glomerular Filtration Rate, is a measurement that reflects how effectively our kidneys filter waste products from the blood. It serves as a key diagnostic and monitoring tool for healthcare professionals.

By knowing one’s eGFR, doctors can identify and track kidney-related issues promptly. This not only helps in the early detection of kidney diseases but also helps in determining appropriate treatment plans.

Several factors, such as age, gender, and serum creatinine levels, influence eGFR and its reviews. By being aware of these factors and regularly monitoring eGFR, you can take proactive steps to maintain optimal kidney health.

How Does a Free eGFR Calculator Work?

This tool works by utilizing specific principles and algorithms to estimate the Glomerular Filtration Rate.

  • Factors considered by a Free this tool include:
    • Serum creatinine levels: This is a waste product produced by muscle metabolism that is filtered by the kidneys.
    • Age: Age is an important factor as kidney function naturally declines with age.
    • Gender: There are slight differences in eGFR values between males and females due to variations in muscle mass and other physiological factors.

The algorithm used in these tools is based on extensive research and statistical analysis. These calculators provide convenient and quick estimations of eGFR by inputting the necessary information.

How to Calculate GFR from Creatinine and Urea

To determine the Glomerular Filtration Rate (GFR) using creatinine and urea levels, follow these steps:

  1. Measure the serum creatinine and urine urea levels.
  2. Multiply the serum creatinine concentration by 0.85 for females or 0.74 for males.
  3. Calculate the urine creatinine concentration.
  4. Multiply urine creatinine by the urine volume produced in 24 hours.
  5. Divide the product from step 4 by the product from step 3.
  6. Multiply the result by 1.73 (the body surface area constant in square meters).

Using these steps, you can calculate GFR from creatinine and urea levels accurately.

Tips for using This Tool effectively

  • Obtain serum creatinine values from reliable laboratory tests.
  • Follow proper protocols for sample collection and handling to avoid any potential errors.
  • Take into account factors such as age, and gender, as they can influence eGFR values.
  • Understand that eGFR calculations are estimations and may have limitations in certain medical conditions.
  • Use this tool as a tool for self-assessment, but always consult healthcare professionals for a comprehensive evaluation of kidney function.
  • Healthcare professionals can provide valuable insights, interpret the eGFR results in the context of an individual’s overall health, and offer appropriate guidance or treatment plans.
