What happens if your creatinine levels are too high?

The healthy kidneys keep blood creatinine in a normal range.The level of creatinine in the blood is a pretty accurate indication of kidney function. A high creatinine level in the blood indicates improper kidney functioning or that you might have kidney disease.The creatinine level will grow when the kidneys become impaired that leading to poor creatinine clearance by the kidneys. Calculating how much creatinine is removed from the body by the kidneys provides a more precise measure of renal function. This is known as creatinine clearance, and it measures the rate at which the kidneys filter waste,also called Glomerular filtration rate (GFR). There are two methods for determining creatinine clearance. It can be computed using a formula that takes into account the patient's weight, age, and blood creatinine level. Collecting a 24-hour urine sample and then extracting a blood sample can also be used to determine creatinine clearance. The amounts of creatinine in the urine and blood a
