Overview of the Anti-Liver Cytosol Antibodies
The Anti-Liver Cytosol Antibodies blood test is a specialist autoimmune investigation that looks for antibodies directed against liver cytosol type 1, commonly referred to as anti-LC1 antibodies.
Anti-LC1 antibodies are associated particularly with autoimmune hepatitis type 2 (AIH-2). They may occur alongside Liver Kidney Microsomal type 1 antibodies (anti-LKM1), although in some people anti-LC1 can be detected as the main or only recognised liver-related autoantibody.
The test contains 1 biomarker: Anti-Liver Cytosol Antibodies. It may be requested when liver enzymes are persistently abnormal, autoimmune hepatitis is being investigated or previous autoimmune liver testing has not fully explained the clinical picture.
Anti-LC1 antibodies target an intracellular liver enzyme known as formiminotransferase cyclodeaminase (FTCD). Their presence can provide useful diagnostic information, but a positive result does not independently confirm autoimmune hepatitis. Diagnosis usually requires assessment of liver enzymes, immunoglobulins, other autoantibodies, medical history and, in some cases, liver imaging or biopsy.
Likewise, a negative Anti-Liver Cytosol Antibodies result does not exclude autoimmune hepatitis or other forms of liver disease. The result should always be interpreted within the wider clinical and laboratory context.
What Does the Anti-Liver Cytosol Antibodies Test Check?
This test measures 1 biomarker.
Anti-Liver Cytosol Antibodies
Detects antibodies directed against liver cytosol type 1 (LC1), principally targeting the liver enzyme formiminotransferase cyclodeaminase. Anti-LC1 antibodies are associated particularly with autoimmune hepatitis type 2 and may occur independently or alongside Liver Kidney Microsomal type 1 antibodies. The result provides supporting diagnostic information but should not be used alone to confirm or exclude autoimmune hepatitis.
Who May Benefit From the Anti-Liver Cytosol Antibodies Test?
This test may be suitable for people in whom autoimmune liver disease is being investigated, particularly where symptoms, liver enzymes or other autoimmune findings suggest possible autoimmune hepatitis.
Suspected autoimmune hepatitis - Anti-LC1 testing can provide additional serological information when autoimmune hepatitis forms part of the clinical differential diagnosis.
Persistently raised ALT or AST - Unexplained liver enzyme abnormalities may prompt investigation for autoimmune as well as metabolic, infectious, medication-related and other liver conditions.
Possible autoimmune hepatitis type 2 - Anti-LC1 is particularly associated with type 2 autoimmune hepatitis and may be assessed alongside anti-LKM1.
Previous inconclusive autoimmune testing - Anti-LC1 may occasionally provide additional information when other liver autoantibodies are negative or inconclusive.
Known anti-LKM1 positivity - Anti-LC1 can coexist with Liver Kidney Microsomal type 1 antibodies and may provide additional autoimmune liver information.
Unexplained chronic liver inflammation - Specialist autoantibody testing may be appropriate when other causes of persistent liver inflammation have not been established.
Personal history of autoimmune disease - Autoimmune conditions can sometimes occur together, making targeted investigation relevant where liver abnormalities are also present.
Family history of autoimmune disorders - Family history may add context when otherwise unexplained liver abnormalities are being investigated.
Specialist-requested liver autoantibody testing - The test can be arranged privately where a hepatologist, gastroenterologist or GP has specifically requested Anti-Liver Cytosol Antibodies.
How to Prepare
Do not stop corticosteroids, immunosuppressants or other prescribed medication simply to alter an antibody result unless specifically instructed by the clinician responsible for your treatment.
Providing previous liver results can be particularly useful because Anti-LC1 is interpreted as part of a wider autoimmune liver assessment rather than in isolation.
Symptoms and Reasons to Consider the Anti-Liver Cytosol Antibodies Test
You may wish to consider the Anti-Liver Cytosol Antibodies test if autoimmune liver disease is being investigated because of symptoms, abnormal liver blood tests or other clinical findings.
Persistent fatigue - Fatigue can occur with liver and autoimmune conditions but is highly non-specific and has many other possible causes.
Unexplained jaundice - Yellowing of the skin or eyes can indicate impaired bilirubin processing and requires appropriate medical assessment.
Persistently abnormal liver enzymes - Raised ALT or AST without an established explanation may lead to additional autoimmune liver investigations.
Upper abdominal discomfort - Persistent discomfort around the liver area may form part of a broader liver assessment, although it is not specific to autoimmune hepatitis.
Dark urine - Dark urine occurring with jaundice or pale stools may indicate liver or biliary disease and warrants clinical evaluation.
Pale stools - Changes in stool colour can occasionally accompany impaired bile flow and should be considered alongside other symptoms.
Unexplained nausea or reduced appetite - These symptoms may occur in liver disease but have many gastrointestinal and systemic causes.
Generalised itching - Persistent pruritus can occur with some liver and biliary disorders and may justify further investigation when unexplained.
Joint or muscle discomfort alongside abnormal liver tests - Systemic autoimmune symptoms may occasionally occur alongside autoimmune liver disease.
Previous autoimmune liver antibody abnormalities - Anti-LC1 may provide additional information when ANA, SMA, LKM or other autoimmune investigations have already been performed.
Autoimmune hepatitis can present in very different ways. Some people have symptoms, while others are identified because routine blood tests show abnormal liver enzymes.
Anti-LC1 is an important specialist antibody, but it is not completely specific to autoimmune hepatitis and should not be interpreted as a diagnosis on its own. Rare positivity can occur in other settings, including some people with hepatitis C.
Jaundice, severe abdominal pain, confusion, persistent vomiting, marked drowsiness, abdominal swelling or rapidly worsening illness require prompt medical assessment rather than waiting for routine private blood test results.
How to Book Your Anti-Liver Cytosol Antibodies Test
Booking your Anti-Liver Cytosol Antibodies test with London Blood Tests is simple and designed to fit around your schedule.
Choose the Anti-Liver Cytosol Antibodies
Select the Anti-Liver Cytosol Antibodies test online and review the included autoimmune liver biomarker before booking.
Select your sample collection option
Choose an in-clinic blood draw (+£35) or a home or hotel phlebotomy visit (+£60) where a qualified phlebotomist collects your sample.
Attend your appointment
A trained professional will collect your blood sample safely and efficiently at the clinic or during your arranged home or hotel visit.
Laboratory analysis
Your sample is sent to the laboratory, where Anti-Liver Cytosol Antibodies are assessed using specialist autoimmune serology.
Receive your results securely
Your results are sent securely by email, ready to review yourself or discuss with a GP, gastroenterologist, hepatologist or other suitably qualified healthcare professional.
When Will I Receive My Results?
The expected turnaround time for the Anti-Liver Cytosol Antibodies test is approximately 5 business days after your sample arrives at the laboratory.
Results are sent securely by email once specialist laboratory analysis and authorisation are complete. Turnaround therefore begins when the laboratory receives the sample rather than necessarily from the time your blood is collected.
Specialist autoimmune testing may occasionally require repeat analysis, confirmation or additional laboratory review, which can extend the expected turnaround.
Understanding Your Results
Your Anti-Liver Cytosol Antibodies result indicates whether anti-LC1 autoantibodies have been detected according to the laboratory method and reporting criteria used.
A positive result can provide important supporting evidence for autoimmune hepatitis type 2, particularly when it occurs alongside compatible liver abnormalities or other autoantibodies such as anti-LKM1.
However, a positive Anti-LC1 result does not independently diagnose autoimmune hepatitis. Clinicians may also consider ALT, AST, bilirubin, immunoglobulin G, other liver autoantibodies, viral hepatitis testing, imaging and sometimes liver histology before establishing a diagnosis.
Anti-LC1 antibodies can occasionally be identified in conditions other than autoimmune hepatitis, including some people with chronic hepatitis C. This makes clinical correlation particularly important.
A negative result does not exclude autoimmune hepatitis. Different forms of autoimmune hepatitis can be associated with different antibody patterns, and some patients may not have detectable Anti-LC1 antibodies.
Reference ranges, assay cut-offs and reporting formats can vary between laboratories. Results should therefore be interpreted according to the laboratory report rather than applying a universal numerical threshold.
