A creatinine level of 2.3 mg/dL in a person with chronic kidney disease (CKD) usually means that the kidneys are moderately impaired and not filtering waste as efficiently as they should.
In most adults, normal creatinine levels are roughly 0.6–1.3 mg/dL. A value of 2.3 is higher than normal and commonly corresponds to CKD Stage 3 (moderate kidney damage), though the exact stage depends on factors like age, sex, body size, and estimated GFR (eGFR).
At this level:
Only a doctor can determine the exact CKD stage and seriousness by checking the eGFR and other tests, not creatinine alone.
