## How do I calculate GFR?

An estimate of the normal value for your GFR can be obtained by using the equation: GFR = 140 – [your age]. For example, if you are a fit, healthy 30 yr old, your GFR should be approximately 110mls/min. Automatic calculators are now available that can directly calculate the GFR.

## What is KDIGO criteria?

What is eGFR normal range?

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.

### What are the three types of AKI?

The causes of acute kidney injury can be divided into three categories (Table 29): prerenal (caused by decreased renal perfusion, often because of volume depletion), intrinsic renal (caused by a process within the kidneys), and postrenal (caused by inadequate drainage of urine distal to the kidneys).

### What is Cardiorenal syndrome?

Cardiorenal syndrome encompasses a spectrum of disorders involving both the heart and kidneys in which acute or chronic dysfunction in 1 organ may induce acute or chronic dysfunction in the other organ. It represents the confluence of heart-kidney interactions across several interfaces.

What does an eGFR of 59 mean?

An eGFR between 30 and 59 means that there is some damage to your kidneys and they are not working as well as they should. Stage 3 is separated into two stages: Stage 3a means you have an eGFR between 45 and 59. Stage 3b means you have an eGFR between 30 and 44.

An estimated glomerular filtration rate (eGFR) of 56 milliliters per minute per 1.73 meters squared is very mild chronic kidney disease (CKD).

## Is a GFR of 53 bad?

when gFR is below 60 for more than three months, this is moderate-to- severe chronic kidney disease. you may be referred to a nephrologist (kidney doctor) for evaluation and treatment. a gFR below 15 means kidney failure. if kidney failure occurs, dialysis or a kidney transplant will be needed to survive.

Guideline development followed an explicit process of evidence review and appraisal.

When to use the CKD EPI equation calculator?

This CKD-EPI equation calculator should be used when S cr is reported in µmol/L. This equation is recommended when eGFR values above 60 mL/min/1.73 m² are desired. GFR = 141 × min(S cr /κ, 1) α × max(S cr /κ, 1)-1
