How To Calculate Gfr From Serum Creatinine
Would serum creatinine or GFR indicate if one kidney is struggling while the other is functioning fine? If not, what testing could identify this?
Physiologic reserve: The body has tremendous redundance for many things, including renal function. So many disorders involving only one kidney's function might be missed with routine GFR or creatinine tests. But on the other hand, most disorders aside from selective vascular or infectious (ascending) disease tend not to just attach one kidney. Single kidney function might be tested by a variety of radiologic tests. ...Read more
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
My lab reports are serum creatinine 80, GFR 72, and creatinine clearance 69.9. my 24 hr urine creatinine was 6.9 and spot urine 2.2. What does it mean?
Not much: You're 55 years old and -- congratulations -- a recovered problem drinker. Unless you're especially fit or heavily-muscled, your creatinine may be a bit high and maybe your kidneys are getting old -- but this level is perfectly compatible with good health and if you had serious kidney disease, it would be a lot worse by now. Eat sensibly, stay fit and I bet your kidneys will last a lifetime. ...Read more
Serum creatinine is 0.96 mg/dL. I am a male. 56 years old and weigh 73.8 kg. Calculated Cockcroft-Gault CrCl is 83.8. Bun is 8 mg/dL. Should I worry?
To get proper result: Creatinine clearance testing procedure and what measured is fully answered in prior question. The serum creatinine must be drawn right after the 24 hour urine collection to calculate how much creatinine is in serum and compare it to the total creatinine in the urine collection, to get an accurate measurement of renal function. ...Read more
Creatinine clearance: People who want to find out their renal function will collect a 24 hour urine for creatinine clearance. The blood sample is used to calculate the clearance of creatinine in the urine as it will be sent off for a creatinine level. Without it, the clearance of creatinine could not be calculated. The result of the test give the actual glomerular filtration rate of the patient. ...Read more
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
Probably: The more important parameter is your GFR. This is calculated based on age, creatinine and weight. If it is over 60, there is no contraindication to using metformin. A young male who is very muscular may have a high creatinine but normal GFR. The usual cut off level for not using metformin in men is a creatine above 1.5 ...Read more
Need more info: The creatinine level is within normal limits but you can get more information from the estimated glomerular filtration rate. To calculate the estimated glomerular filtration rate one needs to plug in creatinine, age, sex and race. See this site for info and discuss the matter with your doctor. http://www.kidneyfund.org/kidney-health/kidney-basics/kidney-test-egfr.html. ...Read more
