Question

Know the difference between creatinine clearance and serum creatinine levels:

a. Creatinine clearance measures kidney function; serum creatinine levels indicate muscle mass

b. Creatinine clearance measures muscle mass; serum creatinine levels indicate kidney function

c. Both measure kidney function, but creatinine clearance is more accurate

d. Both measure muscle mass, but serum creatinine levels are more reliable

Answer 1

Creatinine clearance measures kidney function, while serum creatinine levels indicate muscle mass.

Step-by-step explanation:

The difference between creatinine clearance and serum creatinine levels is that creatinine clearance measures kidney function, while serum creatinine levels indicate muscle mass. Creatinine clearance is a test used to measure glomerular filtration rate (GFR), which is the volume of fluid filtered from the renal glomerular capillaries into the Bowman's capsule per unit time. Creatinine is produced naturally by the body and is filtered by the glomerulus and secreted by the renal tubules. It can be calculated using values for creatinine concentration in urine, urine flow rate, and creatinine concentration in plasma.
