Liver disease test panel - autoimmune
Protein levels:
The normal range for protein levels in the blood will change with each laboratory. Please check with your health care provider for the normal ranges in your particular laboratory.
Antibodies:
Negative results on all antibodies are normal.
Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
Blood tests for autoimmune diseases are not completely accurate. They can have false negative results (you have the disease, but the test is negative) and false positive results (you do not have the disease, but the test is positive).
A “weakly positive” or “low titer positive” test for autoimmune disease is often not due to any disease.
A positive test on the panel may indicate autoimmune hepatitis or other autoimmune liver disease.
If the test is positive mostly for anti-mitochondrial antibodies, there is a high probability of primary biliary cirrhosis.
If the immune proteins are high and albumin is low, you may have liver cirrhosis or chronic active hepatitis.
