Myoglobin with Mass Concentration (Serum/Plasma)

Why Is This Test Done?

Your healthcare provider may order this test if you have symptoms like muscle pain, weakness, or unusual fatigue, especially after exercise or trauma. It may also be used to check for conditions like heart attacks (myocardial infarction) or muscle disorders.

What Does a High or Low Level Mean?

Elevated myoglobin levels can signal muscle injury (e.g., from overexertion, strains, or crush injuries) or heart-related issues like a heart attack. Very low levels are rare but may indicate severe muscle wasting or certain genetic disorders.

How Is the Test Performed?

A blood sample is taken from a vein in your arm. The sample is sent to a lab where myoglobin is measured using a specialized technique, often an immunoassay or enzymatic method, to detect its concentration.

What Are Common Causes?

Common causes of elevated myoglobin include muscle injuries (e.g., rhabdomyolysis), heart attacks, severe dehydration, or certain medications. Rarely, genetic muscle disorders or extreme exercise (e.g., marathon running) can also trigger elevated levels.
