Creatinine in Serum analysis is a test used to measure creatinine levels in the blood. Creatinine is a waste product produced as a result of muscle metabolism. It is filtered from the body through the kidneys, so measuring creatinine levels is an important indicator for assessing kidney health. This analysis is typically performed as part of a routine checkup or when symptoms suggest kidney problems, such as body swelling, high blood pressure, or changes in urine output. Elevated creatinine levels are considered a sign of impaired kidney function, which may indicate conditions such as kidney failure or kidney damage. The test results can also be used alongside other measurements, such as the glomerular filtration rate (GFR), to provide a clearer picture of kidney health. Overall, creatinine analysis is a vital tool for assessing kidney function and monitoring the progression of related health conditions.
