Serum Creatinine

Serum creatinine is a waste product produced by muscles during normal activity. It is filtered out of the blood by the kidneys and excreted in urine. Measuring serum creatinine levels helps assess how well the kidneys are functioning. If the levels are elevated, it may indicate that the kidneys are not working properly, since they are not effectively removing this waste. This test is a common part of kidney health evaluations and can help detect or monitor kidney disease. Overall, serum creatinine provides valuable information about kidney efficiency and helps guide medical decisions.
