MYO (Myoglobin)
Early muscle injury detection for rapid clinical decisions.
Myoglobin (MYO) is a small oxygen-binding protein found in skeletal and cardiac muscle. This test measures the level of myoglobin in the blood and is used to help detect muscle damage. It is particularly useful in the early assessment of suspected acute myocardial infarction (heart attack) and in evaluating rhabdomyolysis (severe muscle breakdown), as myoglobin rises faster than many other cardiac markers. The test may be requested for patients presenting with chest pain, unexplained muscle weakness, dark urine, or following trauma or crush injuries. It can also aid in monitoring conditions that affect skeletal muscle.

Why it matters
Myoglobin is one of the earliest markers to rise after muscle injury, making it valuable for rapid triage. Elevated levels can indicate cardiac muscle damage or skeletal muscle breakdown, helping clinicians initiate timely investigations and management. However, because myoglobin is not entirely specific to the heart, results are interpreted alongside clinical findings and other cardiac markers such as troponin.

No special preparation required.
For blood tests, we recommend drinking plenty of water beforehand to ensure smooth sample collection. If you are taking any regular medication, continue to do so unless advised otherwise by your doctor.
Important Clinical Information:
This test is a screening tool to monitor and support your overall health. It does not replace your GP or Consultant.
Always discuss your test results, especially any abnormal results, with your GP, who can interpret them in the context of your medical history and overall health.
