Creatinine

Creatinine is a test designed to measure the concentration of a waste product called creatinine in your bloodstream. Creatinine is generated by your muscles and is typically eliminated from your body through kidney filtration. This test aids in assessing the efficiency of your kidney function.

In cases where your kidneys are functioning properly, they effectively clear creatinine from your blood. Conversely, if your kidneys are compromised, the level of creatinine in your blood may rise. Elevated creatinine levels may indicate kidney damage or disease.

This test is commonly requested if you exhibit symptoms suggestive of kidney issues, such as frequent urination, swelling in the legs or feet, or changes in urine color. Moreover, it is employed to monitor the progression of kidney disease and to adjust medication dosages for certain conditions.
