Myositis Profile IgG - 16 Antigen near me in Agra

The Ku antibody test is used to detect antibodies against the Ku protein, which is involved in DNA repair and other cellular processes. These antibodies are associated with certain autoimmune diseases, particularly systemic sclerosis, polymyositis and overlap syndrome such as MIxed Connective tissues disease( MCTD). This test is not commonly prescribed as other autoimmune tests but it is useful in diagnosing and differentiating between autoimmune conditions when patients presents with overlapping symptoms like muscle weakness, joint inflammation etc. The presence of Ku antibodies, along with clinical findings and other laboratory tests, helps doctors tailor treatment plans and better understand the patient's autoimmune profile.

The Mi-2 test checks for the presence of autoantibodies that target the Mi-2 nuclear antigen, a protein involved in gene regulation and muscle function. This test is used to help diagnose idiopathic inflammatory myopathies, such as Dermatomyositis (DM) and Polymyositis (PM), which are autoimmune diseases that cause muscle weakness and skin rashes. A positive result indicates the presence of Mi-2 antibodies, suggesting one of these conditions. A negative result means that the antibodies are not found, making these diseases less likely, but it doesn't completely rule them out. Additional tests may be needed for a more accurate diagnosis.

The Jo-1 test is used to detect antibodies against the JO-1 protein, which plays a role in muscle and tissue function. Jo-1 antibody is a myositis-specific autoantibody most commonly found in patients with idiopathic inflammatory myopathies (IIM). This test is primarily used to help diagnose IIM, particularly Dermatomyositis (DM) and Polymyositis (PM). It can be considered a specific marker of IIM, predominantly found in these conditions. The test is also associated with Interstitial Lung Disease (ILD), Raynaud phenomenon, arthritis, and mechanic's hands. A positive result suggests the presence of anti-synthetase syndrome (a rare autoimmune disease that affects multiple systems of the body) or a higher risk of myositis (muscle inflammation). A negative result means the antibodies are not detected, but it does not completely rule out the diagnosis of idiopathic inflammatory myositis. Further tests may be needed for a definitive diagnosis.
