Question

Quizplus · Accepted Answer

Creatinine is a waste product generated by muscle metabolism and eliminated by the kidneys. Its levels in the blood can be used to estimate the glomerular filtration rate (GFR), which is a measure of how well the kidneys are functioning. Therefore, creatinine is the most commonly measured substance to assess kidney function. Glucose, sodium, and potassium levels may also be measured, but they are not the primary indicators of kidney function.
