Kidney and metabolic markers
Check creatinine, eGFR, sodium, potassium, and calcium on one page. Uric acid stays as a linked explanation.

Creatinine is used as part of kidney function assessment. A higher result may be associated with dehydration, muscle mass, medicines, or reduced kidney filtering. Educational only, not a diagnosis.

MedlinePlus and other sources often list slightly different adult bands by sex, and some reports use µmol/L instead of mg/dL. This checker uses mg/dL and one simplified overlapping adult band only for a quick educational check. Muscle mass, hydration, and medicines can affect creatinine. Compare your number with the range and units on your own report.
Enter a valid number to see Low / Normal / High.
This check is for quick educational context only. It is not stored as a medical record and does not replace clinical interpretation. Always compare your result with the reference range printed on your own lab report.

No. Creatinine can be affected by several factors, so clinicians usually interpret it with eGFR, hydration, medicines, and previous results.
Yes. People with greater muscle mass may have higher creatinine even when kidney filtering is otherwise stable.
eGFR uses creatinine as part of a broader estimate of filtering function, so the two are commonly reviewed together.
