is a waste product present in your blood. If the amount of creatinine contained within a sample is too high, your kidneys’ filtering ability (GFR) is likely too low.

How accurate is GFR? A measured GFR is considered the most accurate way to detect changes in kidney status, but measuring the GFR directly is complicated, requires experienced personnel, and is typically performed in a research setting. Because of this, an estimate – the eGFR – is usually used.

What could explain a low GFR? Low GFR signifies poor kidney function ( damaging kidneys). This can happen with underlying diseases like diabetes, hypertension, kidney disease, medications, dehydration. Low uric acid does not have any significance, but uric acid can be falsely low in acute gout attacks.

What is the normal range for GFR? According to the National Kidney Foundation, normal range of GFR is from 90 – 120 mL/min. Older people will have lower normal GFR levels, because GFR decreases with age.

What is a normal GFR? The normal range of GFR, adjusted for body surface area, is 100–130 average 125 mL/min/1.73m 2 in men and 90–120 ml/min/1.73m 2 in women younger than the age of 40. In children, GFR measured by inulin clearance is 110 mL/min/1.73 m 2 until 2 years of age in both sexes, and then it progressively decreases.

Is the GFR test accurate for kidney disease?

Is the GFR test accurate for kidney disease? Are GFR tests accurate? The eGFR test is not 100 percent accurate and it can only give an estimate of your filtration rate. Additionally, the standard formula for calculating eGFR is not valid for people under the age of 18. An eGFR test is usually ordered alongside a urine test for albumin to diagnose kidney disease.

What’s the difference between a GFR calculator and an EGFR? A GFR calculator is a type of mathematical formula that estimates the rate of filtration using some or all of the following information about you: The eGFR is a simple test that can provide very accurate results. Other names: estimated GFR, eGFR, calculated glomerular filtration rate, cGFR

How can I get an estimate of my GFR? So GFR is most often estimated using a test called an estimated GFR or eGFR. To get an estimate, your provider will use a method known as a GFR calculator. A GFR calculator is a type of mathematical formula that estimates the rate of filtration using some or all of the following information about you:

How is the estimated glomerular filtration rate test? eGFR (estimated glomerular filtration rate) is a measure of how well your kidneys are working. Your eGFR is an estimated number based on a blood test and your age, sex, body type and race. eGFR is considered a mostly reliable test for doctors to know how well your kidneys are working.
