Myoglobin

This is a blood test that measures a protein called myoglobin. Myoglobin is found in the muscles of the body (including the heart). With muscle damage, the levels of myoglobin will be increased. This test can be used when skeletal muscle damage or cardiac muscle damage (a heart attack) is suspected.

PREPARATION FOR TEST

No preparation or fasting is necessary. A blood sample is obtained by inserting a needle into a vein in the arm.

NORMAL FINDINGS

Less than 90 μg/L or less than 90 μg/L (SI units)

Ranges for normal findings may vary among different laboratories and hospitals. You should always check with your doctor after having lab work or other tests done to discuss the meaning of your test results and whether your values are considered within normal limits.

MEANING OF TEST

Your caregiver will go over the test results with you and discuss the importance and meaning of your results, as well as treatment options and the need for additional tests if necessary.

It is your responsibility to obtain your test results. Ask the lab or department performing the test when and how you will get your results.
