Sample Required:
A blood sample is required for the MDRD GFR test. This sample is typically drawn from a vein in your arm using a needle.
Test Time:
Results for the MDRD GFR test are usually available within a day, depending on the laboratory’s turnaround time.
Test Normal Range:
The MDRD GFR test doesn’t have a traditional normal range like many other blood tests. Instead, it provides an estimated glomerular filtration rate (eGFR) in milliliters per minute per 1.73 square meters (mL/min/1.73 m²). A normal eGFR is normally greater than 90 mL/min/1.73 m2.
What is the Test?
The MDRD GFR test, also known as the estimated glomerular filtration rate (eGFR), is a measure of kidney function. It estimates how well your kidneys are filtering waste products from your blood.
Test Procedure:
The MDRD GFR test is conducted using a blood sample. The procedure involves these steps:
A healthcare provider or phlebotomist will cleanse the site from which the blood will be drawn, often the inside of your elbow or the back of your hand.
A needle is used to collect a blood sample into a tube.
The blood sample is sent to a laboratory for analysis, where the eGFR is calculated based on creatinine levels, age, gender, and race.
When to Take the Test:
The MDRD GFR test is typically ordered when your healthcare provider suspects or needs to monitor kidney dysfunction. It is also performed routinely in individuals with known kidney disease.
Who Should Take This Test:
People with diabetes, high blood pressure, or other conditions that can affect kidney function may undergo this test as part of their regular health monitoring. Additionally, individuals with known kidney disease require periodic eGFR measurements.
Precautions for Exceptional Cases (Pregnancy, etc.):
During pregnancy, eGFR may naturally increase, so it’s important for healthcare providers to consider this when interpreting results. However, the MDRD GFR test is generally safe during pregnancy.
