Priti, letter says 78
eGFR 78
Often discussed as a higher adult band. Still a single letter.
Kidney Function Result Explainer
Places an eGFR or creatinine-style number you already have from a lab letter into a commonly discussed adult band. It does not calculate eGFR from scratch and it is not a CKD diagnosis.
Your details
Copy the eGFR from your letter. We do not invent a kidney equation.
What is this calculator?
Places an eGFR or creatinine-style number you already have from a lab letter into a commonly discussed adult band. It does not calculate eGFR from scratch and it is not a CKD diagnosis.
How it works
- Copy the eGFR number from your letter, in the unit printed there.
- Read the band as a discussion label.
- Take the original letter to your GP. Do not change medicines from this page.
Common questions
What is the kidney function result explainer?
A band label for a number you already have. Use the GFR calculator if you need a Cockcroft-style estimate from creatinine.
Does a low eGFR mean I have kidney disease?
Not on its own. GPs look at trend, urine tests and you. This page cannot do that.
Why is there no ethnicity box?
We will not invent a CKD-EPI ethnicity adjustment. That belongs in a lab report.
Example scenarios
Doug, letter says 52
eGFR 52
A commonly watched mid band. Ask your GP how they read the trend.
Laila, letter says 28
eGFR 28
A lower band that should already be in a clinic conversation. Use the letter, not this page, for decisions.
Understanding your results
One number without the rest of the report is a fragment. The GFR calculator is the honest maths tool if you only have creatinine.
