Myoglobin

What is a myoglobin serum test, and why is it done?

The myoglobin serum test measures myoglobin protein levels in the blood, which helps detect:

Muscle injuries (rhabdomyolysis, trauma)
Heart damage (early signs of a heart attack)



What do high myoglobin levels indicate?

Elevated levels suggest:

Heart attack or cardiac arrest
Muscle breakdown from injury, excessive exercise, or certain diseases
Kidney problems, as myoglobin buildup can lead to acute kidney injury



How do I prepare for a myoglobin test?

No special preparation is needed, but strenuous exercise before the test may temporarily elevate myoglobin levels.
