ratio, plasma - Renal clearance ratio

The renal clearance ratio is a measure of the speed at which a constituent of urine passes through the kidneys. It is defined by following equation: : clearance\ ratio\ of\ X = \frac{C_x}{C_{in}} *X is the analyte substance *C x is the renal plasma c

The renal clearance ratio is a measure of the speed at which a constituent of urine passes through the kidneys. It is defined by following equation:

:

clearance\ ratio\ of\ X = \frac{C_x}{C_{in}}

*X is the analyte substance
*C_x is the renal plasma clearance of X
*C_in is the renal plasma clearance of inulin.

Creatinine is sometimes used instead of inulin as the reference substance.
