Kidney function is primarily measured by the glomerular filtration rate (GFR), which represents the rate at which blood is filtered through the kidneys. This can be estimated using various formulas that take into account factors such as age, sex, race, and serum creatinine levels. Other tests, such as measuring the amount of urine produced over a 24-hour period, can also provide information about kidney function but are not as accurate as the GFR measurement. Choice C and D are processes that occur within the tubules of the kidney and do not directly measure kidney function. Therefore, the best choice is B.
