Creatinine And Gfr
I am told my Glomerular filtration Rate is 57.6. Does this indicate Kidney disease? Creatinine is 1.0 BUN is 20 total Protein is 7.0 I am 55 w/f
GFR: Your Estimated filtration rate is borderline. This is not a problem itself. The important concern is whether disease exists that might be progressive. Serum creatinine of 1.0 is "normal". So is serum creatinine 1.1. However, creatinine relates to muscle mass. If you are small muscled as a. 55 yo woman, then creatinine of 1.1 or 1.0 may indicate some minor impairment in its excretion. ...Read moreSee 2 more doctor answers
Would serum creatinine or GFR indicate if one kidney is struggling while the other is functioning fine? If not, what testing could identify this?
Physiologic reserve: The body has tremendous redundance for many things, including renal function. So many disorders involving only one kidney's function might be missed with routine GFR or creatinine tests. But on the other hand, most disorders aside from selective vascular or infectious (ascending) disease tend not to just attach one kidney. Single kidney function might be tested by a variety of radiologic tests. ...Read more
My lab reports are serum creatinine 80, GFR 72, and creatinine clearance 69.9. my 24 hr urine creatinine was 6.9 and spot urine 2.2. What does it mean?
Not much: You're 55 years old and -- congratulations -- a recovered problem drinker. Unless you're especially fit or heavily-muscled, your creatinine may be a bit high and maybe your kidneys are getting old -- but this level is perfectly compatible with good health and if you had serious kidney disease, it would be a lot worse by now. Eat sensibly, stay fit and I bet your kidneys will last a lifetime. ...Read more
Sort of: The true glomerular filtration rate is very hard to measure. The creatinine clearance is a practical way of measuring it, which requires a timed urine collection and a blood sample. It is much more accurate then the crude and subscientific estimate of the glomerular filtration rate / GFR from a spot creatinine. ...Read more
High creatinine: You should be referred to a nephrologist to better answer your question. A nephrologist will take a history and do a physical exam. If you did not have a 24 hour urine collection for a creatinine clearance and protein, you need to have one done. You will also need to have blood work and a renal ultrasound done as well to arrive at a diagnosis of what is causing your creatinine to be elevated. ...Read moreSee 1 more doctor answer
Not reabsorbed: Creatinine is used to calculate glomerular filtration rates because the kidney does not reabsorb it: whatever gets filtered into the glomerulus ends up in the urine. So it is a reliable indicator of how much blood has been filtered. All you have to calculate is the volume of blood that contained the amount of creatinine that appeared in the urine over a certain time. ...Read more
Yes: True glomerular filtration rate is very hard to determine, but it can be estimated crudely using the creatinine clearance, which looks at serum and urine creatinine concentrations in a timed and volume-measured urine. This in turn is far more accurate than the subscientific estimate of GFR that's often part of a lab panel. ...Read more
I'm African American. Please explain what these results should mean to me. BUN 19, Creatinine 1.28, GFR 46.
What would be a reason for high creatinine and low GFR for the last 6 work up. I had an ultrasound and it was normal.
My creatinine is 105 gfr is 82 i dont have diabetes or high BP.how can i improve kidney function.should i be worried?
How do you FEEL?: If you're a reasonably well-muscled young man, that creatinine is normal. The GFR's estimates are subscientific; I believe they've been added to make people think they need to take unnecessar medicines. There's even a racial adjustment "because black people are more muscular." When I was lifting weights daily, I was suddenly a kidney case. I'm not and I bet you are not either. ...Read more
