What is Creatinine?

Creatinine is a waste product that is produced when muscles break down creatine phosphate, which is used by the muscles for energy. Creatinine is then filtered out of the blood by the kidneys and excreted in urine.

Creatinine is a commonly used marker of kidney function because the level of creatinine in the blood is largely dependent on the glomerular filtration rate (GFR), which is a measure of how well the kidneys are filtering waste products out of the blood. If the kidneys are not functioning properly, creatinine levels in the blood will be elevated. Therefore, measuring the level of creatinine in the blood can help doctors diagnose and monitor kidney problems.

But the level of creatinine in blood is not the ultimate statement for Kidney disease. Listen to this podcast to know all doubts you have about rising creatinine.
