Does drinking water before the creatinine test affect the results?

Staying hydrated is important for accurate creatinine test results. Dehydration can lead to higher creatinine levels because it reduces the kidneys' ability to filter waste properly. Drinking water before your test ensures that your kidneys are functioning optimally, leading to more accurate results. However, excessive fluid intake right before the test is not necessary. Just maintain normal hydration habits and avoid becoming dehydrated before the test.
