What is creatinine?

There is a creatine byproduct called creatinine. Your muscles get their fuel from a substance called creatine, which is produced naturally in your body. Muscle tissue degrades due to the metabolic process. The breakdown of muscle tissue releases creatinine into the circulation. In this step, creatine is broken down into creatinine.

The kidneys are responsible for eliminating creatinine from the blood. If you consider each organ within your body to perform a certain function, the kidneys would be the filters. Your blood is purified by these guys. What is drawn from your blood is excreted in your pee. Creatinine levels in the blood may be abnormally high if the kidneys are not functioning normally.

What is Creatinine Test?

The health of your kidneys may be evaluated using a serum creatinine test, often known as a creatinine test. Creatinine is an intermediate in the pyruvate pathway, and it is produced when muscle is broken down. When it is produced, it is filtered by the kidneys and excreted in the urine. The glomerular filtration rate (an indicator of how effectively your kidneys are able to filter blood) may be calculated based on your kidneys’ capacity to process creatinine (GFR).

Results of Creatinine Test

Kidney disease is indicated by a decreased GFR. There are two types of kidney failure: acute (sudden, usually curable) and chronic (long-term and permanent). The acuteness or chronicity of renal disease may be determined by repeating GFR measurements throughout time.

Both GFR and kidney function decline with aging. Your kidneys, thankfully, are equipped with a lot of spare capacity. Loss of 30–40% of renal function often does not cause serious health issues in humans.

The Glomerular Filtration Rate (GFR) is used in a staging system to determine the degree of chronic kidney disease:

Creatinine levels in the blood may be normal, however those over the age of 60 are at increased risk for having a GFR that is below normal. On the other hand, there may be no genuine renal disease present despite a slightly reduced GFR. To more precisely classify which of these patients have kidney disease and which do not, the 24-hour urine collection technique or another blood test called cystatin C may be used.
