Serum Creatinine Interpretation
A serum creatinine level of 1.14 mg/dL is within commonly reported adult reference ranges for many laboratories. [1]
Typical Reference Ranges
Common reference ranges reported for serum creatinine include:
- Adult men: 0.74 to 1.35 mg/dL. [1]
- Adult men: 0.7 to 1.3 mg/dL. [4]
- Adult women: 0.5 to 0.95 mg/dL. [2]
Clinical Context Required
Serum creatinine “normality” depends on factors such as sex, age, muscle mass, and the lab’s specific reference interval, so interpretation should be based on the reference range printed on the patient’s report and the estimated glomerular filtration rate (eGFR). [4]
When Further Evaluation Is Important
A creatinine level that is within the lab range can still be associated with kidney disease in some people, so assessment should use eGFR and urine testing when concern exists. [3]
Follow-Up Testing to Consider
If kidney function status is unclear, the most informative next step is typically eGFR calculation (based on the creatinine result) and consideration of urinalysis for albumin/protein per clinician judgment. [4]
