What is the normal range for eGFR in blood tests?
A normal eGFR is 60 or more. If your eGFR is less than 60 for three months or more, your kidneys may not be working well. Use this chart to see what your eGFR may mean.
When should I worry about eGFR?
Stage 5 (eGFR below 15) is a sign of kidney failure. It means you have less than 15% kidney function. This stage is the most serious and can be life-threatening. You will need dialysis (a machine to filter your blood) or a kidney transplant.
What does a creatinine level of 1.8 mean?
People with only one kidney may have a normal creatinine level of about 1.8 or 1.9. Creatinine levels of 2.0 or more in infants and 5.0 or more in adults may indicate severe kidney damage. People who are dehydrated may have elevated creatinine levels.
Can GFR go up and down?
This rate determines whether kidney function is normal or low. Your creatinine levels and GFR can fluctuate over time depending on your fluid levels.
What is the EGFR of the kidneys?
The eGFR (expressed in ml/min/1.73 m2) represents the volume of blood (in millilitres) purified by the kidneys every minute. The calculation is adjusted for a normal-size person (body surface area of 1.73 m2) between 18 and 70 years of age.
What does EGFR of 60 and 89 mean?
The eGFR (expressed in ml/min/1.73 m2) represents the volume of blood (in millilitres) purified by the kidneys every minute. The calculation is adjusted for a normal-size person (body surface area of 1.73 m2) between 18 and 70 years of age. The results are interpreted as follows: 60 and 89: possibly slight decrease in kidney function. Between
Does Quest Diagnostics offer creatinine and EGFR tests?

What factors affect the EGFR value?
Factors that can affect creatinine measurements, and therefore eGFR calculations, include extremes of muscle mass, muscle injury, diets high in meat, hepatic cirrhosis, and certain drugs. Table 2. Interpretation of eGFR Values 2,a
