Myoglobin

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 or acute myocardial infarction: AMI. However, more recent studies indicate that other 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.

No special preparation is needed for Myoglobin. Inform your doctor if you are on any medications or have any underlying medical conditions or allergies before undergoing Myoglobin. Your doctor depending on your condition will give specific instructions.
