Can you say kidney is normal if creatinine levels are within limits?

Creatinine levels within the normal range do not necessarily indicate perfectly normal kidneys. Creatinine is a waste product produced by muscle metabolism, and its levels in the blood can be influenced by factors such as age, muscle mass, and diet. While elevated creatinine levels can be indicative of kidney damage, normal creatinine levels do not guarantee the absence of any kidney abnormalities. Other parameters, such as the urine analysis, urine output, and imaging studies, may be required to comprehensively assess kidney function and identify potential issues.
