Creatinine

What is a Creatinine Blood Test?
The measurement of creatinine in serum or plasma is one of the most widely used tests to evaluate kidney (renal) function. It provides essential insight into how well the kidneys are filtering waste from the blood.

What is Creatinine?
Creatinine is a waste product formed from the breakdown of creatine phosphate in muscle tissue. Its production in the body is generally stable and directly related to an individual’s muscle mass.

How Creatinine is Processed by the Kidneys
Creatinine is primarily filtered out of the blood by the glomeruli in the kidneys. Under normal conditions, it is not reabsorbed by the renal tubules in significant amounts. However, a small portion of creatinine is actively secreted by the kidneys.

Why Creatinine Testing is Important
Creatinine levels in the blood help assess kidney health. Elevated creatinine levels may indicate impaired kidney function or damage, while normal levels typically reflect healthy renal performance.
