Creatinine is a chemical waste molecule that is generated from muscle metabolism. Measurement of this is an indicator of the levels of other waste products in the body. Creatinine is an accurate marker of kidney function.
Elevated creatinine can be caused by high intake of animal protein, taking creatine supplements and vigorous exercise but can also indicate that the kidneys are not working properly.
Low creatinine can be caused by a low protein diet, reduced muscle mass or sometime that the kidneys are simply functioning efficiently.
The estimated glomerular filtration rate (eGFR) assesses how well the kidneys are working by estimating the amount of blood filtered through the kidneys. The glomeruli are tiny filters in the kidneys responsible for removing waste products. If these filters do not do their job properly, kidney function can be impaired. The eGFR calculation is an estimate of actual glomerular filtration rate, calculated using your age, gender and serum creatinine levels.
A normal or high eGFR indicates good kidney function.
A low eGFR result can indicate your kidneys are not working as well as they should. eGFR can be used to assess the severity of chronic kidney disease (CKD).
It is important to note that individuals with high muscle mass as well as people of certain ethnicities can have a low eGFR which is normal for them. If kidney damage is suspected then other investigative tests are recommended.
