Clinical Information
Myoglobin is a heme protein found in smooth and skeletal muscles. Serum myoglobin reflects a balance between intravascular release of myoglobin from muscle and renal clearance.
Previously serum myoglobin had been advocated as a sensitive marker for early acute myocardial injury (eg, acute myocardial infarction: AMI). However, more recent studies indicate that newer markers (eg, troponin) provide superior diagnostic utility in detecting early myocardial injury.
Elevation of serum myoglobin may occur as a result of muscle trauma, resuscitation, myopathies, AMI, shock, strenuous body activity, or decreased elimination during renal insufficiency. Extreme elevations occur in rhabdomyolysis. Creatine kinase is released from muscle and used more commonly for this purpose.
Interpretation
Elevated myoglobin levels are seen in conditions of acute muscle injury.
