Normal blood creatinine levels vary and depend on age, race, gender, and body size. Normal serum creatinine ranges are: 0.6–1.1 mg/dL in women and adolescents aged 16 and older; 0.8–1.3 mg/dL in men and adolescents aged 16 and older; 0.2 or more in infants, depending on muscle development

Your serum creatinine level is based on a blood test that measures the amount of creatinine in your blood. It tells how well your kidneys are working. When your kidneys are not working well, your serum creatinine level goes up. Your doctor can also measure creatinine with a urine test.

Learn what creatinine is, how it is measured, and what causes high or low levels in the blood. Find out how creatinine levels vary by age, sex, muscle mass, and pregnancy.

There are various health conditions that can cause high and low creatinine levels. but – with proper treatment – you can return creatinine levels back to normal.

The serum (blood) creatinine test is a blood test used to check how well your kidneys are filtering your blood. It is usually ordered in combination with other tests as part of a bundle called the “basic metabolic panel” (BMP) or “comprehensive metabolic panel” (CMP).

Learn how serum creatinine, a waste product in your blood, can indicate kidney function and CKD stage. Find out how to measure your kidney health and other CKD health numbers with blood and urine tests.

A creatinine test, also called a serum creatinine test, measures how well your kidneys are working. Creatinine is a waste product from the normal breakdown of muscle tissue. As your body...

It can be calculated (estimated) by a formula using serum (blood) creatinine level, patient's weight, and age. The formula is 140 minus the patient's age in years times their weight in kilograms (times 0.85 for women), divided by 72 times the serum creatinine level in mg/dL.

Assessment of Renal Function. Several clinical laboratory tests help investigate and evaluate kidney function. Clinically, the most practical tests for assessing renal function are those that estimate the glomerular filtration rate (eGFR) and quantify proteinuria (albuminuria). Glomerular Filtration Rate.
