Mitochondrial Antibody Profile (Serum) – Immunoassay Panel
This test measures antibodies against mitochondrial proteins, which may help diagnose certain autoimmune conditions affecting the liver, kidneys, or other organs.
["This test helps identify autoimmune disorders linked to mitochondrial antibodies, often used in conditions like autoimmune hepatitis or mixed connective tissue disease."]

What This Test Measures
The test detects specific antibodies (immunoglobulins) that target mitochondrial components in your blood. These antibodies can be part of an autoimmune response, where your immune system mistakenly attacks healthy cells. The panel typically includes tests for common mitochondrial antigens, such as those associated with autoimmune hepatitis or other systemic autoimmune diseases.
Why It’s Ordered
Your healthcare provider may order this test if you have symptoms like fatigue, liver issues (e.g., jaundice, abdominal pain), kidney problems, or other signs of autoimmune disease. It may also be used to monitor treatment progress or confirm a diagnosis in suspected cases.
Sample Collection and Preparation
A blood sample is drawn from a vein in your arm. The serum portion (liquid part after clotting) is separated and sent to the lab for testing. This test is typically done on fresh or stored serum samples, often analyzed using immunoassay methods to detect antibody presence.
Common Conditions Linked to Positive Results
Positive results may suggest autoimmune conditions like autoimmune hepatitis, systemic lupus erythematosus (SLE), or other mitochondrial-related autoimmune disorders. However, false positives can occur, so results are often interpreted alongside clinical findings and other tests.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Mitochondrial antibodies can indicate an autoimmune attack on organs like the liver, kidneys, or heart. While not all positive results lead to a definitive diagnosis, they can support a clinical suspicion of autoimmune disease. This test is particularly useful in diagnosing conditions where mitochondrial dysfunction plays a role, such as autoimmune hepatitis or certain forms of mixed connective tissue disease.
