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

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 more

Would serum creatinine or GFR indicate if one kidney is struggling while the other is functioning fine? If not, what testing could identify this?

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

Nephrologist: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, the results suggest kidney disease. You should consult a kidney doctor, nephrologist, for an evaluation and treatment. Do not delay seeing a kidney doctor to prevent further deterioration. Wish you good health! ...Read more

Prolactin and kidney: Hi. Those are two unrelated conditions. Serum prolactin (PRL) can accumulate in chronic kidney disease (CKD), but your CKD is way too mild to cause that. Ergo, you have hyperprolactinemia. Do you have amenorrhea and galactorrhea? If not, the PRL may be a red herring, and macroprolactinemia should be tested for. Why you fall into the category of Stage 4 CKD is unknown to us. So, eval. PRL and CKD ...Read more

Should I be concerned with normal BUN, creatinine of 1.16, and GFR 53?

Depends on age: If you are overall healthy and young then the GFR is a touch low. If you are older and the GFR is holding steady it's nothing to worry about. The creatinine is less significant, we usually focus on the GFR. Contact us for more details but it doesn't sound alarming. ...Read more

Is GFR 78 bad for 19 y.O. Male, 185 cm, 82 kg? No issues besides that. Creatinine is 1.27.

What calculation: Was made to determine this. Most of the lab tests and calculations are not meaningful for anyone under the age of 21. If you do not have difficulty with urination and no other symptoms, it seems unlikely you'd have a problem. If you are not sure, or have sue symptoms that could be kidney failure - go see a nephrologist to be tested. ...Read more

Possibly: Gfr is the fluid flow rate between the glomerular capillaries and the bowman's capsule. Gfr just below 60 indicates very mild decrease. Important to have levels rechecked, eat healthy and stay away from medicines and conditions such as massive protein break down taxing the kidney. ...Read more

Creatinine serum 1.5 mg/dl gfr 47-nb bun test 27 how bad is this. Can there be ways to improve on these results. Thank you?

Big picture: Everybody's kidney function declines some with age. I'm good with your BUN especially if you eat a lot of protein. And if you're a mature athlete, this may even be fine; creatinine varies with a man's muscularity. When i was lifting weights daily in my early thirties, my creatinine run 1.5 to 1.6 -- perfectly healthy. ...Read more

What kind of condition does the asian person have if creatinine is .60 normal but GFR is less at 59 for 28 years old?

You're fine: Many other pathologists and nephrologists agree with me that the "estimated GFR's" are misleading and subscientific. The fact that there's an adjustment for black people "because black people are more muscular" suggests a misuse of data. Many people are being told they're sick when they're not. Your creatinine is perfectly fine and I would stop worrying unless there's something else concerning. ...Read more

CKD: Have your health care provider measure your cystatin c. You can then use a version of the ckd-epi equation (found on-line) that incorporates cystatin c to more accurately determine your gfr. Of course, if your urinalysis has protein, you technically already have kidney disease. ...Read more

What is a creatinine clearance rate and GFR?

CrCl & GFR: GFR stands for Glomerular Filtration Rate which is a measure of the filtering function of your kidneys. Creatinine Clearance is one of the methods used to measure a person's GFR and it is often done by measuring the amount of creatinine in a 24 hr urine collection or can be estimated by using an equation called "Cockcroft-Gault" formula. ...Read more

Are creatinine clearance and GFR the same thing?

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

My bun is 31 creatinine is1.6, GFR is35.4. Is this really bad?

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 more

What is the most common cause of the creatinine and bun to be in the normal range and the GFR to be a low 51?

Inconsistent: By definition, creatinine is not normal if the GFR is 51. GFR is calculated from serum creatinine value and if the GFR is below 90, that equates to higher creatinine than would be normal for that person. ...Read more

Low GFR, one kidney: You may hace chronic kidney disease (ckd). Your creatinine level is dependent is your age, sex, race and weight. You are the one to determine what those are. I would suggest you see a neprhologist and collect a 24 hour urine to see how well your one kidney is working. Another test that can be done is an ultrasound of your one kidney to see its size and to see if there is any presence of ckd. ...Read more

I am a female recently completed a 24 hour catch. My creatinine serum was 1.06 & GFR 56. 3 weeks prior GFR was 59. Should I be concerned?

Tests vary: so the difference between 56 and 59 isn't meaningful BUT that is a bit abnormal for a person 55 or younger. So, some reason for concern if you dont' already know why youe kidneys are being studied so closely. ...Read more

High risk: Only you can make that decision, but you certainly an make an informed one. The pregnancy is going to be quite high risk, and could certainly put extra strain on your current conditions. However, these can also be managed if you want kids. You need to start working with a maternal-fetal medicine specialist at least six months before conception to ensure your body is optimal for a pregnancy. ...Read more

I have CKD Stage 3, 2 months ago my GFR was 52 and my Creatinine was152, this week my GFR was 37 and creatinine was 190, I had pneumonia 6 weeks ago could that have caused such a big change?

Yes : Your renal function tests will fluctuate with your overall health, medications, body composition, hydration as well as whatever is going on with your kidneys. GFR estimates are subscientific. You owe it to yourself to ask exactly what is up and whether you have actual renal disease that needs specific management. ...Read more

Why might it be that we use urine creatinine when caclucating GFR ?

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

GFR is 33 and creatinine is 145. I was wondering what is the percentage of kidney function?

Remember: That the GFR is basically an estimation of a degree of your kidney function based on your creatinine measurement, age, gender and race. It may not be accurate if your body type(shape) is extreme or you have significantly more or less muscle mass than "normal". Normal is around 100 by GFR. ...Read more

My GFR is 49 and my creatinine level is within normal levels at 12. Do i need a second opinion as my gp does not seem to be concerned.

Kidney Disease?: If your GFR was obtained by a 24 hour urine collection for creatinine clearance, you have stage 3 chronic kidney disease (ckd). You should be referred to a nephrologist (n), as at some point you will have some of the chemical abnormalities associated with ckd, these are anemia and elevation of your parathyroid hormone. You will also need to have a renal ultrasound to see the size of your kidneys. ...Read more
