Overview of the Mitochondrial Antibodies Test
The Mitochondrial Antibodies blood test detects antimitochondrial antibodies, commonly abbreviated to AMA, which are strongly associated with primary biliary cholangitis.
The test assesses 1 autoimmune biomarker: Mitochondrial Antibodies.
Primary biliary cholangitis, or PBC, is a chronic autoimmune liver disease in which immune activity progressively damages small bile ducts within the liver.
Mitochondrial antibodies are found in the large majority of people with established PBC.
The most clinically specific antibody subtype is directed against the M2 mitochondrial antigen.
A general Mitochondrial Antibody test can therefore provide important evidence when PBC is suspected.
The antibody should not be interpreted alone.
PBC assessment typically also considers Alkaline Phosphatase, Gamma-Glutamyltransferase, Bilirubin, Immunoglobulin M and other liver-function results.
A positive AMA result in somebody with a persistent cholestatic liver-enzyme pattern strongly supports the diagnosis.
However, low-level antibodies can occasionally occur in people without clinically evident PBC or alongside other autoimmune disease.
A negative result does not exclude every case of PBC.
AMA-negative disease exists and can require other liver-specific autoantibodies or specialist investigation.
The test is distinct from Mitochondrial Antibodies M2, which specifically assesses the M2 antigen.
Where the general screen is positive or clinical suspicion is strong, M2 testing may provide additional specificity.
What Does the Mitochondrial Antibodies Test Check?
The test detects autoantibodies directed against mitochondrial antigens. This test measures 1 specialist biomarker.
Mitochondrial Antibodies
Detects antimitochondrial antibodies associated particularly with primary biliary cholangitis and selected autoimmune liver disorders.
Who May Benefit From the Mitochondrial Antibodies Test?
AMA testing is principally useful where liver results or symptoms raise concern about autoimmune cholestatic liver disease.
People with persistently raised Alkaline Phosphatase - A cholestatic liver pattern is a common reason to investigate PBC.
People with unexplained raised Gamma-Glutamyltransferase - AMA can form part of autoimmune liver assessment.
People with persistent itching and abnormal liver tests - Pruritus can occur in cholestatic liver disease.
People with unexplained fatigue and a cholestatic biochemical pattern - PBC can initially present with non-specific symptoms.
People with another autoimmune disorder and abnormal liver results - Autoimmune diseases can cluster.
People with a previous positive AMA result - M2 testing and specialist liver assessment may provide additional information.
People undergoing an Autoantibody Profile - AMA is an established autoimmune liver marker.
People referred by hepatology or gastroenterology - The result can contribute to a broader PBC investigation.
How to Prepare
Do not stop prescribed liver or immune treatment solely to influence antibody testing.
The antibody result is most informative when interpreted with the biochemical liver pattern.
Symptoms and Reasons to Consider the Mitochondrial Antibodies Test
Early PBC can be asymptomatic and discovered after abnormal liver blood tests.
Persistent itching - Cholestasis can cause significant pruritus.
Unexplained fatigue with abnormal liver enzymes - PBC can cause fatigue, although this symptom is non-specific.
Persistently raised Alkaline Phosphatase - This is an important biochemical clue.
Right upper abdominal discomfort - Liver and biliary conditions can cause discomfort.
Dry eyes or dry mouth with autoimmune features - Autoimmune conditions can coexist.
Unexpected cholestatic liver results - AMA testing can help determine whether an autoimmune cause is present.
Jaundice, marked abdominal swelling, confusion, gastrointestinal bleeding or severe liver-related symptoms require prompt medical assessment.
Mitochondrial Antibodies should not be used as a standalone diagnosis of liver disease.
How to Book Your Mitochondrial Antibodies Test

Receive your results securely
Your authorised result is delivered securely and can be interpreted alongside M2 antibodies and liver-function testing where appropriate.
When Will I Receive My Results?
The current specialist laboratory turnaround for Mitochondrial Antibodies is approximately 3 days after laboratory receipt.
This is a specialist immunology assay.
Additional M2 or autoimmune liver testing can have a separate turnaround.
Understanding Your Results
A negative result means significant Mitochondrial Antibodies were not detected by the assay.
This makes classic AMA-positive PBC less likely but does not completely exclude autoimmune biliary disease.
A positive result indicates detectable antimitochondrial antibodies.
When a positive result occurs together with a persistent cholestatic liver pattern, particularly raised Alkaline Phosphatase, it provides strong support for PBC assessment.
Low-level positivity can occasionally be found outside clinically evident PBC.
The result should therefore be interpreted with liver biochemistry and clinical history.
Mitochondrial Antibodies M2 can provide a more specific follow-up measurement where required.
Why Book With London Blood Tests?
London Blood Tests provides private AMA testing for focused autoimmune liver assessment.
Measures a key PBC-associated antibody - AMA is strongly associated with primary biliary cholangitis.
Useful with raised Alkaline Phosphatase - Antibody testing can clarify an unexplained cholestatic liver pattern.
Can complement M2 testing - Mitochondrial Antibodies M2 provides more specific antigen assessment.
Can complement liver-function testing - ALP, GGT and Bilirubin remain important.
Relevant to broader autoimmune investigation - PBC can coexist with other autoimmune disorders.
Specialist immunology analysis - Samples undergo dedicated autoantibody testing.
Professional blood collection - Clinic and suitable home or hotel appointments are available.
Clear pricing - The Mitochondrial Antibodies test costs £70.99.
