If my serum creatinine increased but within normal range is it certain I will develope ckd?I'm so worried to have ckd.

If my serum creatinine increased but within normal range is it certain I will develope ckd?I'm so worried to have ckd.

Stop worrying: Jeff, someone has perhaps misled you. Everyone will at some time in his/her life will have creatinine increase -- it always happens at puberty, especially in males, and it happens to any young man who starts a fitness program. These are not thoughts that you should be having -- life's hard enough without this. Please talk frankly with a competent, caring physician. ...Read more

Serum Creatinine 0.98 serum jaffe method.last month it was 1.2 but in different lab. Is jaffe standard method and what is normal range??

Labs vary: Even different instruments both running the Jaffe will often produce different results. For creatinine, this is famous. And you may have put on a bit more muscle in the interim. "Reference range" varies from lab to lab as well, and it's by no means the same as "healthy range" -- it's set so that several percent of healthies fall outside on either end. A creatinine of 1.2 is no concern for a guy. ...Read more

Spot Urine creatinine rising...has gone from 15 mg to 121mg ...can't find normal range? Is that abnormal? Trace protein Serum creatinine was normal.

Means nothing: Nothing whatever. Your body puts out a constant amount of creatinine proportional to your skeletal muscle mass. You dilute it by however much water you drink. It's reported so that other substances, similarly diluted or not, can be reported "per gram of creatinine". ...Read more

Yes: Serum creatinine varies with muscularity. When I was lifting weights every day, mine ran 1.6-1.7. That's fine given my lifestyle. Stop worrying about individual lab tests especially if your physician isn't concerned. Best wishes. ...Read more

I'm 29 years old, 177cm height and 81kg weight. Don't have any chronic diseases. My serum creatinine value is 1.22 mg/dl (0.7-1.2 mg/dl). Is it normal?

Yes: This is fine, especially for a robust young man. "Reference range" is set to include most couch potatoes, but if you'll even fairly well muscled, you'll be above. When I was lifting every day I ran 1.6; a competitive bodybuilder runs 2.0 or more. ...Read more

How is the serum creatinine in blood brought to normal?

How is the serum creatinine in blood brought to normal?

Normal creatinine: Your creatinine (c) can be brought to your baseline line level if its elevation is caused by acute renal failure, renal failure by an obstruction that is relieved in time or by stopping renal toxic agents such as motrin-like drugs. Most of the time, the cause of an elevated c is not reversible as it is due to some disease affecting the kidneys. See a nephrologist for more information. Good luck. ...Read more

A patient has 9 mg/dl range of serum creatinine. How it can be reduced?

A patient has 9 mg/dl range of serum creatinine. How it can be reduced?

High creatinine: It may not be able to be reduced. A patient not on dialysis with a creatinine level (cl) of 9 is quite sick. Patients with a cl so high not in the hospital should be. The cl may be reduced if is due to some renal drug toxicity or some obstruction. It is best to have this person seen by a physician as soon as possible as his potassium level may be life-threatening. ...Read more

How can a patient with 1335 umol/l range of serum creatinine be helped?

High creatinine: It may not be able to be reduced. See a nephrologist (n) and have a 24-hour urine collection, with protein, to assess your kidney function. You will also need some blood work and a renal ultrasound. Once the n has the results of all of your tests, you can get diagnosis of your problem along with a prognosis of how it will affect you. Good luck. ...Read more

Just ignore this: Labs are set so that a few percent of healthies fall outside on either end. This could not be due to illness. Be thankful for a normal creatinine clearance and that your physician took time to check it. ...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?

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

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

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

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

My hb is 10 ESR is high. All other reports are normal. Yet serum creatinine remains between 1, 8 to2.2. What may b reason. What remedies. Yes I have bp.

High creatinine: At your age, your elevated serum creatinine (c) is due to chronic kidney disease (ckd). It could be caused by your high bp. See a nephrologist for a 24-hour urine collection for a c clearance and protein. It will give you an exact amount of your kidney function. You will also need a renal ultrasound and some blood work. Once these data are in, a more informed idea can be made about your kidneys. ...Read more

I'm very worried. My serum creatinine is 1.09mg/dl, compute egfr in internet and its 90. Over 90 is normal. Do i havekdney dse? My s. Crea 4yrs ago .96mg

Probably not: Assuming you are of normal weight, a serum creatinine of 1.09 is normal. Gfr calculators are just estimates of kidney function. Based on your hydration status, this number can fluctuate somewhat. Your test 4 years ago is probably not significantly different from the current reading. ...Read more

Cr 24/kg is 27.2 (creatinine clearance). Normal is up to 24. Worried about hyperfiltration, not abnormally muscular. 4 months ago serum creatinine was .88 and BUN 12. Weight is 195lbs 22% bodyfat.

Hyper-filtration?: I do not understand what you mean by "Cr 24/kg" Perhaps one of the nephrologists at HealthTap does but creatinine clearance is a volume per minute measurement and normal value for a 23-year old white male is 90 to 140ml/min and 110 to 170ml/min in black males. Based on your weight, age, and creatinine your clearance is approximately 163ml/min which is excellent (there's no such thing as too high) ...Read more

7 day old nephew has a .11mg/dl serum creatinine. Is it normal? He received high dose of amikacin by mistake 3 days before the blood test. Thanks.

Cr .11: Is it 0 .11 or 1.1? 0.11 seems low but that usually is not a problem, 1.1 may be minimally high which coudl be due to dehydration so would recheck it in a week after drinking about 2 glasses water to see the trend and could also dip the urine for protein. . But most important call the lab where it was done and ask for their reference values as every lab differs an it in what is normal ...Read more

I am doing heavy exercise and taking high protein diet since last 6mths. Now my serum creatinine is 1.8, could this be normal? I have no other symptom

Good for you!: Yes. It's usual for bodybuilders to have a serum creatinine up to 2.0. When I was lifting daily, mine ran 1.6 to 1.7. The current fad for interpreting creatinines and estimating gfr's out of context is unscientific and has caused complaints in the peer-reviewed literature from pathologists and nephrologists. Keep it up. ...Read more
