Transglutaminase Ab IgA **

The ENA-6 Profile test is used to detect specific autoantibodies directed against extractable nuclear antigens (ENAs) associated with systemic autoimmune connective tissue diseases. This panel includes antibodies against SSA (Ro), SSB (La), U1-snRNP (RNP68/70 kDa), Sm, Scl-70, and Jo-1. Identifying these autoantibodies supports the diagnosis and differentiation of conditions such as systemic lupus erythematosus (SLE), Sjögren’s syndrome, mixed connective-tissue disease (MCTD), systemic sclerosis (Scleroderma), and idiopathic inflammatory myopathies.

The Protein S (Functional Assay) test is used to assess the activity level of protein S in the body, identify protein S deficiency and the risk of blood clot formation, and assist in monitoring and adjusting treatment for thrombotic disorders

TTG IgG is done in individuals with IgA deficiency.
Evaluating patients suspected of having celiac disease, including patients with compatible clinical symptoms, patients with atypical symptoms, and individuals at increased risk (family history, previous diagnosis with associated disorder, positivity for HLA DQ2 and/or DQ8..
Screening test for dermatitis herpetiformis, in conjunction with an endomysial antibody test.
Monitoring response to gluten-free diet in patients with dermatitis herpetiformis and celiac disease

C3 is part of the complement system, a group of nearly 60 proteins that work with your immune system, playing a role in protecting the body from infections and removing dead cells or foreign materials. This blood test is often used to diagnose or monitor autoimmune disorders like lupus and rheumatoid arthritis.
