Which test measures the level of creatinine in blood and urine?

Creatinine test
Creatinine/BUN ratio
GFR
Urea test

The correct answer is: Creatinine test

The creatinine test is specifically designed to measure the level of creatinine in both blood and urine. Creatinine is a waste product produced from muscle metabolism and is normally eliminated from the body by the kidneys. The measurement of creatinine levels in the blood provides insight into kidney function; elevated levels may indicate impaired kidney function or kidney damage. Additionally, the creatinine test can also be paired with urine tests to provide a more comprehensive view of kidney health, such as in the assessment of creatinine clearance, which evaluates how well the kidneys are filtering creatinine from the bloodstream. Other options focus on different aspects of kidney function or related metabolic waste products, but they do not specifically measure creatinine levels in both blood and urine.
