Myoglobin

This test measures myoglobin, a protein released into the bloodstream after muscle injury.

Diagnostic Value: Elevated myoglobin is an early but non-specific marker of heart or skeletal muscle damage.

Clinical Significance: Used as a rapid screening test in combination with Troponin and CK-MB for suspected heart attack.

Symptom Correlation: May correlate with chest pain or muscle tenderness.

The Myoglobin test provides early detection of muscle injury before other cardiac markers rise.
