What is the MDRD GFR equation?
Estimates glomerular filtration rate based on creatinine and patient characteristics.
What is GFR calculated abbreviated MDRD mean?
In adults, the most widely-used equations for estimating glomerular filtration rate (GFR) from serum creatinine are the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation1 and the isotope dilution mass spectrometry (IDMS) traceable Modification of Diet in Renal Disease (MDRD) Study equation2.
What does 60 mL/min 1.73m2 mean?
The GFR (glomerular filtration rate) is a formula that uses age, race, gender and serum creatinine level to measure kidney function. Patients who have a GFR less than 60 ml/min/1.73 m2 for three months or more are diagnosed as having CKD. Kidney disease progresses as the number of nephrons (filtering units) diminish.
Why is CKD EPI better than MDRD?
The CKD-EPI equation, a newly developed equation for estimating GFR, has been proposed to be more accurate than the MDRD equation, especially when GFR is high. Moreover, it shows less bias, improved precision, and greater accuracy[8].
What does GFR 90 ml/min 1.73m2 mean?
An eGFR of >90 ml/min/1.73m2 is considered normal kidney function. If these patients have evidence of kidney disease* (see below) these patients have CKD stage G1. Patients with an eGFR of 60-90 ml/min/1.73m2 have mildly reduced kidney function which may be appropriate for their age.
What does 1.73 m2 mean in GFR?
The average eGFR for someone in their 20s is about 116 mL/min/1.73m2. It drops to 85 mL/min/1.73m2 for people in their 60s. An eGFR higher than 60 means you have at least 60% kidney function. Generally, the higher the number, the better your kidney function.
What is average GFR for a 60 year old?
“Normal” GFR is approximately 100, but you will often see it reported as >90 (greater than 90) or >60 (greater than 60)….GFR Number by Age.
| Estimated GFR Number by Age Group | |
|---|---|
| 40-49 | 99 |
| 50-59 | 93 |
| 60-69 | 85 |
| 70+ | 75 |
When was MDRD equation created?
In 1999, an equation derived from measured GFR (mGFR) was developed in the Modification of Diet in Renal Disease (MDRD) Study. This equation included the serum creatinine concentration and six other variables, subsequently abbreviated to four variables [5, 6].
What does mL/min/1.73 m2 mean?
Your eGFR is reported in millilitres per minute which is written as mL/min/1.73m2 (the “1.73m2” indicates a result expressed relative to body surface area). A normal GFR in a young adult is greater than 90 mL/min/1.73m2.
What is the formula to calculate the GFR?

What is the normal range for an estimated GFR?
A GFR of 60 or higher is in the normal range.
What is the MDRD equation?
MDRD Study Equation. eGFR =. 175 x (S Cr) -1.154 x. (age) -0.203 x. 0.742 [if female] x. 1.212 [if Black]
