Question

What is the normal range for glomerular filtration rate (GFR)?

a. 90 to 120 mL/min
b. 0.05 to 1.2 mg/dL
c. 10 to 20 mg/dL
d. 110-115 mL/min

Answer 1

The normal range for GFR is
`90 to 140 mL/min` in males and
`80 to 125 mL/min` in females addressing filtration of plasma by the kidneys per minute.

Step-by-step explanation:

The normal range for glomerular filtration rate (GFR) varies between genders. In males, the normal range is approximately
`90 to 140 mL/min` while in females, it is about
`80 to 125 mL/min` . Thus GFR is the volume of filtrate formed by both kidneys per minute.

A reduction in GFR below
`60 mL/min/1.73 m²` for a duration of three months is indicative of chronic kidney disease (CKD). The GFR illustrates how much plasma enters Bowman's capsule per minute which under normal conditions represents about
`20%` of the plasma volume passing through the kidneys.
