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

Kidney (Definition)

The kidneys are paired organs that lie on either side of the vertebral column. Part of their critical functions include the excretion of urine and removal of nitrogenous wastes products from the blood. They regulate acid-base, electrolyte, fluid balance and blood pressure. Through hormonal signals, the kidneys control the ...Read more

Does a low phoshorus level and low complement C3 but normal bun and creatin level mean kidney failure?

Does a low phoshorus level and low complement C3 but normal bun and creatin level mean kidney failure?

No: Kidney failure is defined by changes in bun/cr and more correctly GFR (glomerular filtration rate) over time. A normal BUN and cr is reassuring. Usually the phosphorus is high with kidney failure. A low complement (c3) level relates to the immune system and a possible deficiency there. ...Read more

My bun was a 10 and my creatine was 0.8. Could i still have kidney failure or would those levels have to be high? I have protein in urine regularly!

My bun was a 10 and my creatine was 0.8. Could i still have kidney failure or would those levels have to be high? I have protein in urine regularly!

Not Likely: Those are healthy kidney numbers. However, you can have other causes of proteinuria or renal insufficiency and should follow up with a nephrologist or your regular doctor. ...Read more

Husb micoalbumin is 596. BUN/Creatinine level is normal.Serum Albumin norm. He's diabetic & has fatty liver.Is he in kidney failure?Why micro high?

Husb micoalbumin is 596. BUN/Creatinine level is normal.Serum Albumin norm. He's diabetic & has fatty liver.Is he in kidney failure?Why micro high?

Diabetic nephropathy: B"sd kidney failure is marked by elevation of creatinine. Microalbumin is a sensitive test for early kidney changes seen in diabetes and hypertension. Unless very high, standard albumin will be normal. Fatty liver is of concern but not directly related. To prevent progression of kidney disease 1. control of diabetes 2. blood pressure control 3. ACE or ARB agent. Glad to discuss ...Read more

Can the bun score which is 50 determine kidney failure?

Can the bun score which is 50 determine kidney failure?

BUN and kidney: You need more than a BUN of 50 mg/dl to diagnose kidney failure. BUN is dependent on the amount of protein being ingested as well as the state of hydration of the patient. You need to have a creatinine level drawn at the same as the BUN to make any intelligent statement of renal function. To get the actual function of a person's kidneys, a 24 hour urine collection for creatinine clearance is done. ...Read more

My BUN/Creatnine is 29 I'm 51 yrs old is this dangerous? Am in kidney failure?

My BUN/Creatnine is 29 I'm 51 yrs old is this dangerous? Am in kidney failure?

Premature conclusion: While a BUN/Cr of 29 is a little high (> 20, which is what is expected), by itself it does not mean kidney failure. The measurements could have been in error. Or there could be a cause (eating meat will raise the BUN). The best determination of kidney failure is the estimated GFR (also known as the Creatinine clearance, CrCl) which is calculated from the Cr as well as age, weight, & symptoms. TTYD ...Read more

Labs: 8/11: bun 20/creatinine 1.4. 1/12: bun 20/creatinine 1.15. 6/1/12: bun 23/creatine 1.39. 6/20/12: bun 17/creatine 1.4. 7/24/12: bun 22/creatinine 1.4. 9/12: bun 24/creatine 1.3. Kidney failure?

Labs: 8/11: bun 20/creatinine 1.4. 1/12: bun 20/creatinine 1.15. 6/1/12: bun 23/creatine 1.39. 6/20/12: bun 17/creatine 1.4. 7/24/12: bun 22/creatinine 1.4. 9/12: bun 24/creatine 1.3. Kidney failure?

I'm puzzled.: Has there been something said that makes you think you are at risk for kidney failure? I'm not seeing this from your labs. The creatinine (a breakdown product from muscle and eliminated by the kidney) is a little generous - but it's not increasing. That's what you would typically see in kidney disease. I'm curious as to the number of tests you've had; make an appt with your doctor to clarify this. ...Read more

Kidney Failure (Definition)

The kidneys do several tasks. Dialysis is necessary when one or more of the following occur, that can't be remedied or palliated with medications: 1. Insufficient clearance of daily toxins in food and metabolic waste 2. Insufficient clearance of excess water 3. Dangerous electrolyte imbalance, ...Read more
