Estimated Creatine Clearance
Clarify: I'm not sure what your question is. Testosterone should be used with caution in patients with conditions involving edema, such as impaired kidney function, as the hormone may worsen edema. One of the adverse effects of testosterone is an increase in serum creatinine concentration. ...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
Different tests: Creatinine is a waste product of (mainly muscle) metabolism, & builds up when the body (kidney) cannot get rid of it. Creatine Phosphokinase, AKA Total CPK, is an enzyme produced by certain cells in the body that produces creatine byproducts (muscle, bone, brain, heart have CPK). An elevated CPK means one of these organs is/was damaged in some way. So the 2 tests measure different things. ...Read moreSee 1 more doctor answer
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
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
Practicalities: Inulin is a strange sugar from the root of chicory and dahlias. It's a researcher's tool for a somewhat more accurate estimate of glomerular filtration than is offered by creatinine clearance. The latter, however, is readily available from blood and urine samples and requires no injection, so it's what is usually used clinically. ...Read more
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 moreSee 1 more doctor answer
Serum Creatinine 1.6, Chloride 108, GFR 48. Would exercise move creatine levels out of normal? A week prior Creatinine 1.4 & Chloride 108. Concerns?
Here are some ...: These reports alone represent your current attainable / acceptable, stable range for your body homeostasis. As long as you have no additional related symptoms, further concern will do no good but practicing healthy lifestyle with no overindulgence / obsession, especially avoiding kidney-insulting drugs, will, a lot. So, live on and ask Doc timely. Best wish ... ...Read moreSee 1 more doctor answer
Serum creatinine 0.49mg/dL, 24h urine cr 22.1mg/dL & cr excretion 884mg, cr clearance 125.4mL/min, random urine cr 109,7mg/dL. Normal? If low, why?
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
What means a high creatinin clearance levels?My serum creatinin is 0, 8ml/dl, and clearance creatinin was 161ml/min with normal values 70 to 130ml/min.
Sounds like: Your kidney function is good and everything is working fine. ...Read more
Glomerular hyperfiltration? My creatinine clearance results was 164ml/min with normal range betw. 70 and 130.Is that glomer. Hyperfiltration?Causes?
Stop worrying: If this was an estimated creatinine clearance based on your serum creatinine, this is sub-science and there's no reason to think you are sick. The problems with these forumulas is showcased in part by a large adjustment for black people "because black people are more muscular than other people." hyperfiltration is a concern when there's clearly kidney disease. ...Read more
Protein Urine Random 35 Creatinine, Ur 143.0 Protein/Creat Ratio 0.2 mg. commet Nephrotic ratio> 3.5 No standard values given. kidneys ok??
Proteinuria: Protein/creatinine ratio of 0.2 is within the normal reference range. So, there is no significant increase in urine protein. I am concerned about hematuria and painful joints. Is hematuria repeatedly present? Is BP normal? Why swollen feet? What other testing has been done? Is ANA present? Have you had a recent infection? Is serum creatinine changing? Is urine albumin/creat ratio known? ...Read moreSee 1 more doctor answer

I have adpkd 24 y/o and trying to gain muscle. My creatine clearance is 87ml/min BUN and creatinine are normal. How much protein can I take in grams?
As you wish: There is no limit on how much protein you can eat. Some cowboy cultures have lived on nothing but meat and suffered no bad effects. Just because some sick people must restrict protein (or gluten, or beer, or many other things) doesn't mean it's wise for you. You do need to know that more than 1 gm of protein daily per pound you weigh is probably wasted even for bodybuilding. ...Read more
Nonsense: Serum creatinine in the US is measured in mgs%. In England and other countries it is measured in micromoles%. Normal serum creatinine is 0.6-1.2 mgs%. The value of 77 mg does not make sense. Is this a measurement from urine or serum? If it is a urinary collection is it timed ie 24 hour collection or spot collection. ...Read more
Creatine.: Creatine in doses of 1000 to 5000mg daily has been shown to increase muscle mass, muscle size and muscle energy stores. Creatine must be taken with lots of water throughout the day, and doses must not exceed 5000mg daily to avoid impairment of kidney function. The dose can be taken all at once, preferably after exercise to facilitate ATP store replenishment in the muscles after exercise. ...Read moreSee 1 more doctor answer
No: At your age, this is something i would watch, but it could be caused by you not drinking enough water before getting your blood drawn. If everything else looked good on your labs, then make sure you drink a glass or two of water before going to the lab next time and see if it goes down. ...Read more
Lots of water: If high cr is due to intrinsic kidney disease, there is no way to realistically change it and no benefit to trying. Creatinine is not the problem, the broken kidney is the problem. If you lose a lot of muscle mass your creatinine will drop and you may drink a lot of water but these do not fix the kidney. ...Read more
Controversial!: Talk to your md before taking creatine or creatine supplements . Creatine use in high school and college athletes( esp. Football and track )has increased tremendously in the past 15 -20 years.Some studies suggest increase performance w/ creatine use in short, " burst" type activities such as sprinting.They are" legal" by ncaa ; but cannot be dispensed by the college.Side effects?Cramping/wt. Gain. ...Read more
Use appropriately : Creating is naturally found in the body and is important in the process of supplying the energy for muscles to work.When used appropriately, can be helpful in refueling the muscle immediately after a work out.However, one of the side effects is drawing water into the muscle tissue and out of circulation basically causing a relative dehydration.Muscle cramping, stomach cramping and nausea can occur. ...Read more
