Which test is used to determine kidney function?

The test used to determine kidney function is Creatinine. Creatinine is a waste product that is produced from normal muscle metabolism and is usually removed from the blood by the kidneys. Measuring the level of creatinine in the blood can indicate how well the kidneys are functioning. If the kidneys are not filtering properly, creatinine levels will rise in the blood, serving as a key indicator of kidney health.

In contrast, while tests such as Bilirubin Total can assess liver function, they do not provide direct information about kidney health. CK Myopathy is more focused on muscle damage rather than kidney function. The BMP (Basic Metabolic Panel) includes a variety of tests, one of which measures creatinine, but is not solely focused on kidney function. Therefore, creatinine is specifically utilized as a direct marker for assessing kidney capabilities.
