Tests
Autoantibody testing checks a sample of your blood for autoantibodies, proteins made by the immune system .
Indicators
An antiphospholipid autoantibody that reacts with beta-2-glycoprotein 1, and a member of family of autoantibodies that cause antiphospholipid antibody syndrome and may be found in system lupus erythematosus.
Indicators
An autoantibody that recognizes histidyl-tRNA synthetase, cytoplasmic protein.
Indicators
An autoantibody that reacts with cardiolipin. Different immunoglobulin subclasses and isotypes are associated with different diseases and conditions. Some anticardiolipin antibodies prolong phospholipid dependent clotting while others are associated with spontaneous abortion.
Indicators
An autoantibody that recognizes antigens found in the cytoplasm of neutrophils.
Tests
This test looks for CCP (cyclic citrullinated peptide) antibodies in your blood. CCP antibodies, also called anti-CCP antibodies, are a type of antibody called autoantibodies. Antibodies and autoantibodies are proteins made by the immune system :
Tests

Tests
The determination of the amount of rheumatoid factor IgM autoantibody present in a sample.
Indicators
An anti-nuclear autoantibody that recognizes a 70 kDa fragment of DNA topoisomerase 1. It is associated with scleroderma.
Tests
The determination of the amount of thyroid stimulating immunoglobulin autoantibody present in a sample.
