Final answer:
A range of 2 to 6.5 mg/dL for a creatinine blood test indicates normal renal function.
Step-by-step explanation:
A range of 2 to 6.5 mg/dL for a creatinine blood test would indicate normal renal function. Creatinine is a waste product produced by the muscles and excreted by the kidneys. The level of creatinine in the blood is used to assess kidney function. A range of 2 to 6.5 mg/dL falls within the normal range for creatinine, indicating that the kidneys are functioning properly.
