creatinine reference range age wise:
- 0-14 days (both genders): 0.32-0.92 mg/dL
- 15 days to <2 years (both genders): 0.10-0.36 mg/dL
- 2-3 years (both genders): 0.20-0.43 mg/dL
- 3 to 5 years (both genders): 0.31-0.51 mg/dL
- 5 years to 17 years (both genders): 0.36-0.84 mg/dL
- more than 18 years (males): 0.6-1.1 mg/dL
- more than 18 years (females): 0.4-0.8 mg/dL.

Deriving and establishing reference ranges specific to a particular laboratory’s patient population is recommended in clinical laboratory medicine.
Creatinine is a waste product generated by muscle metabolism and excreted by the kidneys. Blood creatinine levels are often used as a measure of kidney function.
Purpose of the Creatinine Test:
The primary purpose of the creatinine test is to assess kidney function. Creatinine is a waste product generated by muscle metabolism, and it is typically filtered out of the blood by the kidneys and excreted in urine. When the kidneys are functioning normally, they maintain a relatively stable creatinine level in the blood. Elevated levels of creatinine can be a sign of reduced kidney function.
Creatinine values are often used in conjunction with eGFR calculations to provide a more comprehensive assessment of kidney function.
