## What does the Creatine Kinase (CK) test tell you?

Measures muscle enzyme levels — elevated after intense exercise, muscle injury, or in muscle-wasting conditions.

Creatine Kinase (CK) is an enzyme found primarily in skeletal muscle, cardiac muscle, and the brain. When muscle cells are damaged, CK leaks into the bloodstream. Elevated CK can indicate muscle injury from intense exercise, rhabdomyolysis, myositis, statin-related muscle damage, or cardiac events (CK-MB fraction). It is an important baseline for anyone starting statin therapy or an intense training program.

**Clinical use:** General health testing provides a baseline snapshot of organ function, metabolism, and key biomarkers — useful for annual checkups, preventive care, and tracking changes over time.

## Who should order it?

Adults wanting a routine wellness baseline, anyone re-engaging with healthcare after a gap, and people tracking the impact of lifestyle or medication changes.
