A change from 0.89 to 1.03 in
creatinine, and 114 to 97 in eGFR, is a small shift, and both readings are still within the normal range for most adults. Numbers like these can vary a little with hydration, recent exercise, protein intake the day before the test, or just lab-to-lab differences.
Next Steps
Drink enough water before any repeat test and avoid a heavy protein meal or intense workout the evening before, then recheck in a couple of months to confirm it's stable.
Health Tips
See a physician or nephrologist promptly if you notice swelling in your legs, reduced urine output, or your
creatinine keeps rising on repeat tests.
