At what serum creatinine and blood urea level dialysis should start?

At what serum creatinine and blood urea level dialysis should start?

Onset of dialysis: There are no set levels for BUN and creatinine (c) to start dialysis. The onset of dialysis is determined by a 24 hour urine collection for c clearance. If the patient is a diabetic, dialysis usually starts at a c clearance of 15 ml/min or less. If the patient is a non-diabetic, dialysis starts at a c clearance of. ...Read more

Serum Creatinine (Definition)

Creatinine is a breakdown product of muscle tissue. In the healthy situation it is cleared by the kidneys. Thus, a rise in creatinine is a sign of ...Read more

Blood test: estimated creatinine clearance test (low), what could it indicate? EGFR & creatinine normal. Potassium & sodium low. 28yr/f

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

Sodium-133, potassium-5.2, urea-105, creatinine-4.2. How to reduce the urea and creatinine levels?

High Blood Levels: To properly answer your question, more information is needed. Specifically, your age, weight and race will give a nephrologist an idea of what your kidney function is. You need to have an ultrasound of your kidneys to see if you have obstruction present. Please see a nephrologist so that doctor can do a history and physicalexam and order the ultrasound as well as a 24 hour urine collection. ...Read more

Low creatinine and elevated bun/creatinine ratio. Please explain?

Low creatinine and elevated bun/creatinine ratio. Please explain?

Decrease in flow.: Bun=blood urea nitrogen, byproduct of proteins ingested, if rise to high levels due to kidney problem, can cause toxic affects on the body. Creatinine= measurement of renal function. Normal bun/cr ratio about 10. The higher that ratio, the more likely it is not intrinsic kidney disease per se, but reduction in blood flow or volume to kidney, like when on strong diuretic-prerenal-reversible. ...Read more

See below: An elevated BUN with normal creatinine and a ratio of [generally more than 18-20] occurs most commonly in dehydrated individuals and is not a sign of kidney damage.It may also occur in in certain other conditions like bleeding in the intestines, artificial nutrition intravenously of Amino Acids and use of steroids.Your doctor determines its significance. ...Read more

Low creatinine and elevated bun/creatinine ratioplease interpret?

Stop worrying: Low creatinine is never a health concern. Reference ranges are set so that a few percent of healthies fall outside on either end. The ratio can be up if you're a little thirsty or ate a protein-rich meal lately. ...Read more

High bun and bun/creatinine ratio results so bad kidneys?

Most of time: Generally high BUN and creatinine go hand in hand in bad kidneys(chronic kidney disease)., and bun/creat ratio is 10-15 to 1 , however if ratio >20 may indicate superimposed second cause like dehydration or bleeding in gut. ...Read more

Low creatinine serum, high creatinine clearance and normal urine cret at age 21. Totally sedentary lifestyle with high protein diet. What's thr prob?

Kidney problem?: With the information you provided, I do not think you have a problem with your kidneys. Creatinine is an indication of your kidney function and, just as important, is gives an estimation of your muscle mass. A high creatinine clearance may be seen with uncontrolled diabetes, which you do not have. Speak to the physician who ordered these tests on you for more information, he knows you best. ...Read more

Bun creatinine high in fasting blood work. What are the causes?

BUN and creatinine: If you have high BUN and creatinine levels, you may be dehydrated or you may have chronic kidney disease. Ask the physician who ordered the blood test for an opinion as to the cause of the high levels in the blood. The physician knows the patient best and can give a more meaningful answer to your question. Good luck. ...Read more

How to reduce serum creatinine and blood urea level for 62 yr old male right now the readings are: serum creatinine ---> 2.1 blood urea --->67?

High creatinine: You need to see a nephroloigist (n) for a history, physical examination and lab studies. You need a 24 hour urine for creatinine clearance and protein determination. You also need more blood work and a renal ultrasound to see the size and morphology of your kidneys. If you have some obstruction of your urinary tract, lowering of you elevated levels may be possible. See a n for more infoirmation. ...Read more

High value of creatinine clearance.Serum creatinine 0, 8mg/dl.Creat. Clearance 165ml/min.Normal value from 80 to130.What's the relevance of high value?

High value of creatinine clearance.Serum creatinine 0, 8mg/dl.Creat. Clearance 165ml/min.Normal value from 80 to130.What's the relevance of high value?

Don't worry: A high estimated GFR means nothing whateve except that the estimate has little to do with reality. The fad for estimating glomerular filtration rates in healthy people based on a correlation with serum creatinine is unscientific and has many pathologists and nephrologists unhappy. Ignore it. ...Read more

How can the bun/creatinine ratio indicate dehydration?

May be helpful: There are many causes of an elevated BUN or elevated creatinine, and the ratio between them must be interpreted in the clinical context of each specific patient. What is commonly referred to as "dehydration" usually causes an increase in the BUN to creatinine ratio, but other significant conditions may cause a similar rise and need to be considered, especially if there is an acute illness involved. ...Read more

Which etiology results in an elevated bun level with a normal serum creatinine level?

Which etiology results in an elevated bun level with a normal serum creatinine level?

Multiple causes: BUN is a breakdown of ingested protein, but becomes elevated compared to creatine, in cases of increased catabolism (breakdown). Such things as a high protein diet, use of some steroids, some infections, or volume depletion may commonly raise BUN levels. In a hospital setting, tube feeding, tpn, GI bleeding, infections, decreased flow to the kidneys, and use of steroids are frequent contributors. ...Read more
