What Is Egfr
EGFR: Egfr stands for estimated glomerular filtration rate. It is calculated by a formula that takes into account your sex, age, race, weight and serum creatinine level. As it is an estimate, it is not actual. To get your real gfr, you need to have a 24 hour urine collection for a creatinine clearance. As your doctor to refer you to a nephrologist for the urine collection to see if you have a problem. ...Read more
What does eGFR Female 51L and eGFR Female AA and CREATININE 1.08 mg/dl. Anything to worry about?
Estimated GFR: I don't know that 51L or AA mean. But these "estimates" are subscientific. I'm not the only pathologist who believes that this stuff -- which includes an adjustment for race "because black people are more muscular" -- is best ignored. A creatinine of 1.08 is no concern whatever for a mature woman. Be thankful for good health. ...Read more
Kidney estimate: This is a crude and not-very-scientific estimate of the glomerular filtration rate that labs have begun reporting based on spot serum creatinines, even when they are perfectly normal. Creatinine varies with muscle mass and the adjustment is based on your race (!) rather than your physical exam. Focusing on numbers rather than people is seldom helpful. ...Read moreSee 1 more doctor answer
No such thing: There's an unproven test for one's MTHFR (a folic acid metabolism enzyme) genotype. A majority of people who pay to have it done will be told they have a health problem and the lab will then offer them certain special nutritional supplements. Most pathologists do not believe in this; I'm open-minded but not yet persuaded. ...Read more
Docs keep saying i'm dehydrated, but i drink 1/2 gallon water per day, pee 12 times at least a day. I don't know what else to do? Egfr 57 bun/cre norm
Dehydration?: If your BUN and creatinine are normal, it is very, very unlikely you have dehydration. If your egfr is 57 ml/min, it is unlikely that your have a normal BUN and creatinine, as you chronic kidney disease stage 3. Why don't you ask the physician (p) who ordered the blood work on you that gave you a egfr of 57 what is going on? That p knows you better than anyone else. Good luck. ...Read more
Blood test: estimated creatinine clearance test (low), what could it indicate? EGFR & creatinine normal. Potassium & sodium low. 28yr/f
How do you FEEL?: Many (maybe most) pathologists and nephrologists aren't impressed with the current practice of labs estimate GFR, creatinine clearance and so forth from a spot creatinine. Some formulas include race "because black people are more muscular than white people" -- these were never intended to be applied to individuals. Frankly, if your others labs are healthy, I'd ignore it. ...Read more
What is the significance of egfr if low numbers don't alarm doctors. Mine has been in the 70's and i've had several around 54 and my lowest 49?
Pitfalls of EGFR: Egfr's are estimates, hence the "e". Its unreliability is evidenced, in your case, by the variations you've had your egfr's. .Your egfr is calculated using your age, sex, weight, serum creatinine and race. If you wish to have an accurate value of your actual gfr, have your doctor or a nephrologist order a 24 hour urine for a creatinine clearance. ...Read more
