Myoglobin Blood Test - More Information
This myoglobin test, also known as a myoglobin blood test and a myoglobin lab test, measures the myoglobin blood level.
Myoglobin is a protein found in the muscles. Similar to hemoglobin, myoglobin is able to bind iron and is important for carrying oxygen in the muscle. Myoglobin is pigmented and is responsible for giving meat its characteristic color.
Normally, myoglobin is not present in the blood but is present in high levels in the muscles. In the setting of muscle damage, myoglobin is released from the muscle tissue into the blood. Myoglobin blood levels start increasing within 2 hours and generally decrease 24 hours after the muscle damage stops. One common condition in which this occurs is called rhabdomyolysis. In rhabdomyolysis, skeletal muscles start to break down, often from extreme levels of exercise or traumatic injuries and can lead to kidney dysfunction and even kidney failure. This myoglobin blood test is often ordered with the creatine kinase test as part of a rhabdomyolysis evaluation.
To get a myoglobin test near you, order online and get your blood drawn at the Quest Diagnostics lab that you selected. Once your myoglobin lab report is ready, it will be available for download. As can be seen on the sample myoglobin lab results, the myoglobin blood level will be reported as a number and can be compared against the reference range provided by the lab. This particular myoglobin lab test measures myoglobin blood levels, as opposed to the myoglobin urine test which measure myoglobin urine levels.
