Anti Thyroglobulin antibodies (ATG)
Antithyroglobulin antibodies can be a sign of thyroid gland damage caused by the immune system. They may be measured if thyroiditis is suspected. Measuring thyroglobulin antibody levels after treatment for thyroid cancer can help your provider decide what the best test is to monitor you for a recurrence of the cancer
Anti-double stranded DNA (anti-dsDNA)
Anti-double stranded DNA (Anti-dsDNA) Titre
In the evaluation of someone with lupus nephritis, a high level (titer) of anti-dsDNA is generally associated with ongoing inflammation and damage to the kidneys. A very low level of anti-dsDNA is considered negative but does not exclude a diagnosis of lupus. Only about 65-85% of those with lupus will have anti-dsDNA
Anti-glomerular basement membrane antibody (GBM)
Anti-Mullerian Hormone (AMH)
Anti-MuSK antibody
An anti-MuSK antibody test is used to help diagnose myasthenia gravis (MG) in people with signs and symptoms associated with MG but who test negative for AChR antibodies. Testing is used to distinguish MG from other conditions that may cause similar symptoms, such as chronic muscle fatigue and weakness
Anti-Smith (Sm) antibody
Anti-SSA autoantibodies
Anti-SSB antibodies
Antibodies against SSB/La are present in 40-50% of patients with primary Sjögren syndrome and in 15% of patients with SLE. Finding antibodies against SSB/La in patients without antibodies against SSA/Ro is unusual, but this combination has occurred in patients with primary biliary cirrhosis and autoimmune hepatitis.
Anticardiolipin Antibodies Test ( ACA )
The Anticardiolipin Antibodies Test, or ACA Blood Test, aids in the diagnosis of antiphospholipid syndrome (APS). APS is an autoimmune disorder that produces anticardiolipin antibodies. These antibodies interfere with the blood clotting process, which can result in inappropriate or excessive clotting.
