Do high creatinine levels mean renal failure?

Do high creatinine levels mean renal failure?

High creatinine: Serum c is dependent on the person's weight, race and age. You need to have a 24 hour urine collection for a creatinine (c) clearance determination to know what your renal function is. When the urine is returned, blood is taken for a c level. That is the sure way to know how serious your creatinine level is and what your true renal function is. ...Read more

High bun and bun/creatinine ratio results? Dangerous?

High bun and bun/creatinine ratio results? Dangerous?

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 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

Random sample: urine protein 31mg/l urine albumin 5.00mg/l urine creatinine 3.894mmol/l urine albumin creatinine:ratio 1.3mg/mmol is this normal?

Is this a test?: Slight variation in the reports from different laboratories does exist. So, please refer to the attached normal range for interpretation. I'm sure there is such information for you to reconcile. If any doubt, talk and confirm with the attending doctor. Best ... ...Read more

Dehydrated: 39 F from Indy of unknown ethnicity medical or drugs notes low rbc high bun and high urine Na creat. ANS: sounds like anemia and dehydration or renal disease. The latter is often due to eating too much salt and HTN and choosing the wrong grandparents. Your Dr knows you best so ask them. ...Read more

Does drinking gatorade increased bun creatinine?

No: It's an alternative to soda pop that replenishes some of your electrolytes. If you're an athlete drinking this sports beverage, your BUN may be up from eating steak and your creatinine from putting on muscle. Labs mean nothing without a big picture. ...Read more

Creatinine is elevated but egfr is normal. Kidney disease?

Creatinine is elevated but egfr is normal. Kidney disease?

Maybe/depends,,,: If you are a big person with a normal egfr, and BUN, you might have a high Creatinine due to a lot of muscle mass. However, if you are small, and of light build, you could have an issue, and so a more extensive work up would be needed, including review of your meds, if you are taking any. Best of luck. ...Read more

Elevated creatinine serum what is critical?

Elevated creatinine serum what is critical?

Diagnosis needed: Serum creatinine is affected by protein intake, gender, age, race, muscular build, and renal function. A rising creatinine is always of concern. "normal" on lab tests is generally less than 1.2 mg/dl. Renal function can be estimated with a more complex formula or measured with a 24 h urine collection. See your internist for further evaluation. ...Read more

Glomerular filtration & renal clearance, what is this?

Glomerular filtration & renal clearance, what is this?

GFR: Glomerular filtration is is the amount of filtering that occurs in the glomeruli of the kidney. We use this number (usually an estimation based on creatinine, age, race, sex and albumin) to determine how well the kidneys are functioning. It tells us how much kidney function (or clearance) someone has. ...Read more

What means an urine-to plasma creatinine ratio > 200? My urine creatinine was 171mg/dl, serum creatinine 0.8mg/dl, ratio:213.

What means an urine-to plasma creatinine ratio > 200? My urine creatinine was 171mg/dl, serum creatinine 0.8mg/dl, ratio:213.

Nothing: This is a meaningless number that is primarily a function of how much water you were drinking. It's used to help calculate other labs. ...Read more

What creatinine levels indicate kidney problems?

Varies: Although serum creatinine is routinely tested when blood chemistry is ordered, it is not a standardized test (i.e. different labs will give a slightly different numerical values & direct comparison of values from such labs is not meaningful). Frequently, normal serum creatinine ranges from 0.8 to 1.3 mg/dl. However, other factors such as degree of hydration and the muscle mass of the patient. ...Read more

No problem: The ratio seems high because your creatinine is lower than usual. There is nothing with a low creatinine. Women tend to have lower creatinine due to smaller muscle mass, as compared to men. You lab results are fine. ...Read more
