Test Overview
Clinical Utility
Myoglobin is a heme protein found in smooth, skeletal and cardiac muscle. Serum myoglobin reflects a balance between intravascular release of myoglobin from muscle and renal clearance.
This test is used in the investigation of rhabdomyolytic renal damage. It is not recommended for use as a cardiac marker.
