Kidney Function Test

Is fasting mandatory for a kidney function test?

It's often recommended, particularly when combined with fasting glucose or lipid tests, but confirm the specific requirement with your doctor or the lab beforehand.

What does a high creatinine level mean?

Elevated creatinine usually indicates reduced kidney filtering capacity, though it can also rise temporarily from dehydration, a high-protein meal, or intense exercise, so your doctor will consider the full clinical picture.

Can kidney function improve after being reduced?

It depends on the underlying cause — acute kidney injury from dehydration or a short-term illness often recovers fully, while chronic kidney disease is usually managed to slow progression rather than reversed.

How often should I get my kidney function checked if I have diabetes?

Most guidelines recommend annual kidney function testing for people with diabetes, or more frequently if you already show signs of reduced function.
