What is GFR and its normal value?
According to the National Kidney Foundation, normal results range from 90 to 120 mL/min/1.73 m2. Older people will have lower than normal GFR levels because GFR decreases with age. Normal value ranges may vary slightly among different laboratories.
Should I worry if my GFR is 50?
An estimated glomerular filtration rate (eGFR) of 50 milliliters per minute per 1.73 meters squared is early Stage 3 chronic kidney disease (CKD). You should continue to follow regularly with your physician.
What is mGFR?
The gold standard method is a measured GFR (mGFR) with the clearance of an exogenous ideal marker that is biologically inert and exclusively cleared by glomerular filtration without tubular reabsorption or secretion.
What does a GFR of 118 mean?
“Normal” GFR is approximately 100 but you will often see it reported as >90 (greater than 90) or >60 (greater than 60). The normal range of Kidney Glomerular Filtration Rate is 100 to 130 mL/min/1.73m2 in men and 90 to 120mL/min/1.73m2 in women below the age of 40.
Can you improve GFR levels?
While it’s possible to improve your GFR, you’re more likely to do so with acute kidney injuries rather than with chronic kidney disease. For most people with chronic disease, positive lifestyle changes may help slow the loss of kidney function.
What causes GFR to drop?
A decrease or decline in the GFR implies progression of underlying kidney disease or the occurrence of a superimposed insult to the kidneys. This is most commonly due to problems such as dehydration and volume loss. An improvement in the GFR may indicate that the kidneys are recovering some of their function.
How can I raise my GFR?
How to Increase eGFR
- Make sure your blood pressure is in the healthy range (around 120/80) [17, 18]
- Aim for a healthy weight [18, 24]
- Eat a lot of fruits and vegetables 
- Quit or reduce smoking [18, 22, 26]
- Exercise for at least 30 minutes several times per week [27, 28, 29, 30]
Can your GFR go back up?
Conclusion. GFR improvement is possible in CKD patients at any CKD stage through stage 4–5. It is noteworthy that this GFR improvement is associated with a decrease in the number of metabolic complications over time.
Is GFR reliable?
eGFR (estimated glomerular filtration rate) is a measure of how well your kidneys are working. Your eGFR is an estimated number based on a blood test and your age, sex, body type and race. eGFR is considered a mostly reliable test for doctors to know how well your kidneys are working.
