MPO Blood Test - More Information
The myeloperoxidase test, also known as an anti-myeloperoxidase test, MPO blood test, and MPO lab test, measures the level of anti-myeloperoxidase (MPO) antibody blood level.
Myeloperoxidase (MPO) is a type of protein / enzyme that is found in special types of white blood cells in the immune system. In the presence of foreign invaders, myeloperoxidase is released into the cells and helps destroy microbes attacking the body. MPO levels may also have some role in assessing risk in people with chest pain.
Occasionally, the immune system will malfunction and produce antibodies that cause the MPO enzyme to function inappropriately. Elevated myeloperoxidase antibody levels can cause autoimmune conditions such as vasculitis and polyangiitis. This particular MPO lab test will report whether MPO antibodies are detectable in the blood or not. The MPO blood test can be found as a component of the ANCA test panel.
To get a myeloperoxidase test near you, just order online and get your blood drawn at the selected Quest Diagnostics lab. Once your myeloperoxidase lab report is ready, it will be available for download. As can be seen on the sample myeloperoxidase lab results, the MPO antibody blood levels are reported as a number and can be compared against the reference range provided by the lab.
