Creatinine
What It Is
Creatinine is a waste product from normal muscle metabolism, filtered by the kidneys.
Why It Matters
Creatinine is a key marker of kidney function. Rising levels may indicate declining kidney health.
If Levels Are High
Elevated creatinine may indicate impaired kidney function or dehydration.
If Levels Are Low
Low creatinine can occur with reduced muscle mass or advanced liver disease.
Preparation
Avoid excessive meat intake for 24 hours before the test.
How Often to Test
Annually, or more frequently if monitoring kidney health.
