Myoglobin is a protein in your muscles that helps them get the oxygen they need to keep moving. But it can be a sign of muscle damage if it’s in your blood or pee. Healthcare providers test for it with a simple blood or urine test. You may need other tests to confirm the exact cause.

Learn about the serum myoglobin test, its role in diagnosing muscle and heart conditions, normal myoglobin levels, and causes of elevated myoglobin in blood.
Myoglobin (symbol Mb or MB) is an iron - and oxygen -binding protein found in the cardiac and skeletal muscle tissue of vertebrates in general and in almost all mammals. [5][6][7][8][9] Myoglobin is distantly related to hemoglobin. Compared to hemoglobin, myoglobin has a higher affinity for oxygen and does not have cooperative binding with oxygen like hemoglobin does. [8][10] Myoglobin ...
Myoglobin is a protein found in the muscle cells of animals, where it functions as an oxygen-storage unit, providing oxygen to the working muscles.
Myoglobin (Mb) is an iron-containing heme protein that is present predominantly in the sarcoplasm of skeletal and cardiac muscles. Due to the presence of heme moiety, myoglobin serves as a carrier and store for oxygen in muscle cells of the body. Myoglobin has more affinity for oxygen as compared...
Myoglobin Myoglobin is a relatively small (17.8 kDa) haem-containing protein found in abundance in the cytoplasm of striated muscle cells, where its main function is oxygen transport. Myoglobin accounts for about 2% of total muscle protein. Its high tissue:plasma ratio, in combination with its small size, means that it rapidly increases in the circulation after myocyte necrosis. Indeed, it is ...
