Glomerular filtration rate (GFR) is the best overall index of kidney function. Normal GFR varies according to age, sex, and body size, and declines with age.
Knowing your glomerular filtration rate (GFR) will help you understand how well your kidneys are functioning. Using our GFR calculator, you can find out your estimated GFR and determine which stage of chronic kidney disease (CKD) you may be in.
Your kidneys filter your blood by removing waste and extra water to make urine. The glomerular filtration rate (GFR) shows how well the kidneys are filtering. An estimated 37 million adults in the United States may have chronic kidney disease (CKD) but nearly 90% are unaware of their condition.
This GFR calculator (estimated glomerular filtration rate calculator) is a tool that can help you with detecting a kidney disease at its early stage. Read on to get a better understanding of how it works, how to calculate the GFR from cystatin C and creatinine levels, and what values of estimated GFR (eGFR) are an alarming indicator.
The GFR (glomerular filtration rate) Calculator estimates GFR values based on factors including serum creatinine value, age, race, and gender. For comparison purposes, the results for three prevalent formulas used for estimating GFR are provided.
Use this GFR Calculator tool to help you determine which stage of kidney disease you are in currently. What Your GFR Result Means. Completely healthy kidney function is measured at a glomerular filtration rate (GFR) of around 100, which means that the kidneys are working at 100 percent.
The MDRD GFR Equation estimates glomerular filtration rate based on creatinine and patient characteristics.
Estimated glomerular filtration rate (eGFR) calculators provide an estimate of kidney function. eGFR serves as a key marker for chronic kidney disease and is calculated using estimating equations that may not always be precise.
NIDDK’s eGFR calculator for adults uses the race-free Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations to estimate GFR. The calculator may be used for people ages 18 and older. For patients ages 18 to 25, we recommend using both the adult calculator and the pediatric Chronic Kidney Disease in Children under (age) 25 (CKiD ...
GFR is calculated using a formula that considers factors like age, sex, race, and serum creatinine levels (a waste product in the blood). It’s expressed in milliliters per minute per 1.73 meters squared (mL/min/1.73 m²), which might sound complicated, but don’t worry—we’ll break it all down. The Science Behind the GFR Calculator.
