Myoglobin is a protein found in muscle tissues, including the heart. This test measures the level of myoglobin in the blood. It's primarily used to diagnose heart attacks or muscle injuries. Myoglobin is released into the bloodstream when muscle cells are damaged. In the case of a heart attack, myoglobin levels can rise within 2-3 hours, making it one of the earliest detectable markers. However, it's not specific to the heart and can also indicate skeletal muscle damage. This test is often used in conjunction with other cardiac markers for a more comprehensive assessment of heart health.
A low myoglobin level is generally not a cause for concern. Myoglobin is typically present in small amounts in the blood, and levels below the normal range are not usually associated with any specific medical condition. However, consistently low levels might indicate:
In these cases, further investigation may be necessary to determine the underlying cause.
Elevated myoglobin levels indicate muscle damage, which could be due to:
High levels require immediate medical attention, especially if heart attack is suspected. Additional tests like troponin and CK-MB are often performed to confirm the diagnosis. Kidney function should also be monitored, as excess myoglobin can damage the kidneys.
