Notes
- One reading is not a diagnosis. Creatinine moves with muscle mass, hydration, recent meat intake and some medicines, as well as kidney function itself. A clinician reads it against your history and usually against a repeat, not on its own.
- Reference ranges differ between laboratories. The bands above follow commonly reported adult reference ranges. Your own report prints the range its analyser was calibrated against, and that printed range is the one to compare against — a difference of a few units between labs is normal and does not mean either is wrong.
- Creatinine on its own says less than the eGFR calculated from it. The same value means different things at different ages, sexes and body sizes, which is why laboratories report the estimate alongside it. Read the eGFR first.
- Several ordinary things raise it without the kidneys changing. A large cooked-meat meal the evening before, creatine supplements, intense exercise in the previous day, and dehydration all push it up. So do some drugs — trimethoprim and cimetidine among them — which block creatinine's secretion into urine without affecting filtration at all.
What creatinine of 1.56 mg/dL means

Reading it next to the rest of the picture
A single figure is a snapshot. What a clinician does with it is set by what sits around it — the other results on the same report, what the person is being treated for, what they were doing in the hours before the sample, and what the previous result was. Two people can hand over the same number and leave with different advice, and neither has been given the wrong answer.
That is also why the bands on this page are drawn from a named guideline rather than from a rounded rule of thumb. A threshold is a decision point somebody argued for in print, not a law of nature, and knowing which document a line comes from is what lets you tell a meaningful result from a borderline one.
