Glomerular Filtration Rate
What is analysed?
Glomerular Filtration Rate (GFR) is a key indicator of kidney function. It measures the amount of blood filtered by the glomeruli per unit of time.
What does the result mean?
The GFR result reflects the efficiency of the kidneys in removing waste from the blood. A lower GFR may indicate kidney dysfunction or disease.
Why undergo the analysis?
GFR analysis is crucial for assessing overall kidney health. It helps detect early signs of kidney impairment, enabling timely intervention and management.
When to undergo the analysis?
GFR analysis is recommended in various situations, including routine check-ups, monitoring chronic kidney conditions, or when specific symptoms suggest kidney issues.
What sample is required?
A simple blood test is required for GFR analysis. The test measures the level of a substance (creatinine) in the blood, which correlates with GFR.
Is any prior preparation necessary?
Generally, no specific preparation is needed. However, informing your healthcare provider about medications or supplements is essential, as they can affect the test results.
How is it used?
GFR results aid healthcare professionals in assessing kidney function. It guides treatment decisions and helps determine the stage of kidney disease, if present.
What are the normal values?
|
GFR Range (mL/min) |
Kidney Function Status |
|
90 and above |
Normal |
|
60 – 89 |
Mildly reduced |
|
45 – 59 |
Mild to moderate impairment |
|
30 – 44 |
Moderate to severe impairment |
|
Below 30 |
Severe impairment or failure |
What does having altered values mean?
Altered GFR values may signify kidney disease or dysfunction. Further diagnostic tests and medical evaluation are often required to identify the underlying cause and develop an appropriate treatment plan.
