GFR as a measure for kidney function
GFR (glomerular filtration rate) is equal to the total of the filtration rates of the functioning nephrons in the kidney. GFR is considered the optimal way to measure kidney function, which in conjunction with albuminuria, can help determine the extent of CKD in an individual. The level of GFR and its magnitude of change over time are vital to:
- the detection of kidney disease ...
I am a CKD 3 patient with a GFR of <35, currently under excellent care. I have been stable for over 5 years now. I recently had updated labs and was found to have a potassium of 5.2. I was told to go by my "low potassium food list." However, I am having problems with the nutrition facts for foods that I purchase. Some of them do not even list potassium. I would like to know my maximum potassium mg or grams per day. I have been trying to ask my nephrologist and his staff/nutritionist but am having difficulty getting in touch with them this time of year. Can you give me an idea of how much potassium is too much?
Use this handy sheet to keep track of your GFR and albuminuria results. After each test, fill in your GFR number and albuminuria result, along with the date you were tested.What is GFR?
- GFR stands for "glomerular filtration rate." Your GFR helps you know how much kidney function you have.
- GFR is estimated from a simple blood test. You...
- All GFR estimating formulas on this site are designed for use with standardized creatinine and standardized cystatin C values.
- Standardized creatinine values are traceable to isotope dilution mass spectrometry (IDMS).
- Standardized cystatin C values are traceable to the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC)/Institute for Reference Materials and Measurements (IRMM) working...
