What is the formula for determining GFR?
Your GFR tells you how much kidney function you have. It is defined as the sum of the filtration rates of all your functioning nephrons (filtering units making up the kidneys). An estimate of the normal value for your GFR can be obtained by using the equation: GFR = 140 – [your age].
What is a good GFR for a 70 year old?
Following the classical way, we can assert that normal GFR values are largely over 60 mL/min/1.73 m2 in healthy subjects, at least before the age of 70 years. However, we know that GFR physiologically decreases with age, and in adults older than 70 years, values below 60 mL/min/1.73 m2 could be considered normal.
Should I worry if my GFR is 55?
A GFR of 60 or higher is in the normal range. A GFR below 60 may mean kidney disease. A GFR of 15 or lower may mean kidney failure.
What is the normal GFR for a 74 year old male?
Age- and gender-specific reference values of GFR
| Age (years) | N | Range |
|---|---|---|
| 70–74 | 102 | 38–102 |
| 75–79 | 112 | 41–110 |
| 80–84 | 73 | 41–129 |
| >85 | 33 | 34–101 |
What does a creatinine level of 3.7 mean?
A creatinine of 3.7 milligrams per deciliter (mg/dl) is likely a sign of kidney disease. I suggest that you use this creatinine to go to our web site and calculate her estimated glomerular filtration rate (eGFR).
How does the GFR calculator estimate GFR?
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.
What does it mean when your GFR is 45?
Your kidney function is still considered normal if the GFR number is 90 or greater. If your GFR is 45, you know that your kidneys are working at approximately 45 percent of the normal rate. Stage 1 Kidney Disease Healthy kidneys or kidney damage with normal or high GFR
What is the glomerular filtration rate calculator?
The glomerular filtration rate calculator is the best method to measure the level of your kidney function and determine the stage of kidney disease (1) . Calculating the GFR can help in estimating the extent of damage to the kidneys.
What does a GFR of 100 mean for kidneys?
Completely healthy kidney function is measured at a GFR of around 100, which means that the kidneys are working at 100 percent. Your GFR is , indicating your kidneys are working at approximately percent of the normal rate.
