Answers From Our Expert: Dialysis Treatments & Lab Tests

Q: Where can I find information on normal and abnormal creatinine values?

A: Creatinine is a byproduct of creatine that is found in muscles. The Life Options website has information on lab tests, including normal lab values and how to protect the kidneys.

Another site that has helpful information for people interested in kidney disease is the Nephron Information Center. This site has information specifically for patients as well as information for professionals. There is a place on their website that describes the kidney and even shows how it works.

You can find information on lab values in healthy people as well as for people on dialysis at There is even a calculator that you can use to calculate creatinine clearance (the approximate percentage of remaining kidney function) just by inserting your lab values, age, and sex into fields in the formula.
