OVERVIEW:
What is the renal functioning test?
A renal functioning test is a combination of a urine and blood test that evaluates kidney function.
Why is the renal functioning test done?
A renal functioning test is done in order to:
- Monitor kidney function,
- Diagnose renal impairment,
- Diagnose renal failure,
- Monitor the level of creatinine and urea nitrogen in the blood,
- Detect the presence of glucose, protein or blood in urine.
What does a renal functioning test measure?
A renal functioning test monitors and evaluates kidney function. A renal functioning test works by calculating the glomerular filtration rate (GFR). The glomerular filtration rate determines how quickly and efficiently your kidneys are removing waste products from your body.
Are there any risks associated with this test?
There are no known risks associated with this test.
What is the GFR in patients of kidney disease?
Any GFR value below 60mL/min is an accurate indicator of kidney disease.
What is a normal GFR for a 70 year old?
GFR physiologically decreases with age, and in adults older than 70 years, values below 60 mL/min/1.73 m2 could be considered normal.
Can you have a low GFR and not have kidney disease?
People with mildly low GFR (between 60 and 89) may not have kidney disease if there is no sign of kidney damage, such as protein in their urine.
Can this test be performed in a pregnant female?
This test can be safely performed in a pregnant female.
Normal glomerular filtration rate in adults is 90 – 120 mL/min.
