Myoglobin

Top of the page

Myoglobin

Myoglobin is a protein found in heart tissue and other muscles. It helps trap oxygen in the muscle cells so that the muscles can work properly.

Myoglobin levels in the blood rise after a serious injury, such as a heart attack or a burn.

Strenuous exercise, an injury to a muscle, or an injection into the muscle can cause myoglobin levels to go up. Myoglobin levels also are high in people who have kidney failure, because myoglobin is removed from the blood by the kidneys.
