How to Calculate Your GFR Level: A Step-by-Step Guide

Learn how to accurately calculate your GFR level using the MDRD formula and CKD-EPI equation. Discover practical tips!

1,248 views

Calculating GFR (Glomerular Filtration Rate) involves using the MDRD (Modification of Diet in Renal Disease) formula or CKD-EPI equation. The main variables you need are: serum creatinine level, age, gender, and race. For the MDRD formula: GFR = 175 × (serum creatinine)^-1.154 × (age)^-0.203 × (0.742 if female) × (1.212 if African American). Many online calculators can assist in this calculation by inputting these values.

FAQs & Answers

  1. What is the normal GFR level? A normal GFR level is typically greater than 90 mL/min/1.73 m² for adults.
  2. Why is calculating GFR important? Calculating GFR is crucial for assessing kidney function and detecting early signs of kidney disease.
  3. Can GFR levels change over time? Yes, GFR levels can fluctuate based on various factors including hydration status, diet, medications, and underlying health conditions.
