What is GFR?

GFR is a measure of how much fluid is filtered out of the blood by the kidneys in a given amount of time. It is used to determine how well the kidneys are functioning.

Test Procedure of Glomerular Filtration Rate:

1. The patient is asked to fast for at least 8 hours before the test.
2. The patient is asked to drink plenty of fluids before the test.
3. The patient is asked to avoid strenuous exercise before the test.
4. The patient is asked to urinate in a sterile container.
5. The patient’s blood pressure is measured.
6. The patient is asked to lie down on a table.
7. A needle is inserted into the patient’s arm.
8. The patient’s blood is drawn and collected in a vial.
9. The patient is asked to urinate in a sterile container.
10. The patient’s urine is collected in a vial.
11. The patient’s creatinine level is measured.
12. The patient’s glomerular filtration rate is calculated.

How to Determine chronic kidney disease using GFR (Glomerular Filtration Rate)

The GFR (glomerular filtration rate) can determine chronic kidney disease. The GFR can be estimated from serum creatinine levels using a serum creatinine equation. A decreased GFR indicates that the kidneys are not functioning optimally.

Is creatinine clearance and GFR the same?

No, creatinine clearance and GFR are not the same.

What does it mean to have a low Glomerular Filtration Rate?

A low Glomerular Filtration Rate means that the kidneys are not filtering as much blood as they should. This can be a sign of kidney disease.
