"Is Everything Normal if Only Creatinine Levels Are High?"

1. Everything is normal, with solely elevated creatinine levels. This may be a normal phenomenon or it could indicate a pathological condition.

2. The normal range of creatinine levels is generally 50-110μmol/L for males and 40-100μmol/L for females. Levels above this range are considered elevated. If a patient only has elevated creatinine levels without symptoms such as hematuria, proteinuria, edema, or changes in kidney morphology and function, and the increase in creatinine is not significant, it is usually not considered chronic kidney disease (CKD). The diagnostic criteria for CKD, especially for Stage 2 CKD, specify a glomerular filtration rate between 60-90ml/min. However, if a patient does not exhibit symptoms of kidney disease, they cannot be diagnosed with CKD. If other indicators are normal and there is only a mild elevation in creatinine, it generally cannot be diagnosed as CKD.

3. If other indicators are normal but the creatinine level is significantly elevated, it can be diagnosed as CKD. In such cases, besides normal causes, there may be underlying factors affecting the kidneys, leading to elevated creatinine. Treatment should be considered as necessary to avoid delaying the condition.
