ANA by Immunoblot 17 Antigens Serum Test Cost & Procedure

Antinuclear antibodies (ANA) are identified in your blood by an ANA test. Your immune system often produces antibodies to aid with infection resistance. In contrast, antinuclear antibodies frequently attack the tissues in your body, specifically the nuclei of each cell. The development of an immunological response against oneself and subsequent self-harm are hallmarks of autoimmune illnesses. ANA blot uses Immunoblot technology to find antinuclear antibodies (ANA) in blood. The exam focuses on specific cell nucleus structures. Any one of the 17 antigens that test positive can help distinguish between different autoimmune diseases.

The purpose of the ANA Blot 17 antigens Serum test:

• The serum ANA Blot 17 antigens are re-used to help diagnose autoimmune diseases.
• Joint pain, weariness, and fever are prominent signs and symptoms of many autoimmune disorders, and some also include the kidneys, muscles, eyes, glands, and skin.
• ANA blot tests are advised for additional confirmation, and a more precise diagnosis after a screening test such as an ANA IFA or ELISA is positive.
• Clinical correlation can be used to determine the type of autoimmune condition based on the autoantibodies against the particular antigen.

What is measured by it?

The blood test detects the presence of autoantibodies against 17 antigens, including dsDNA, nucleosomes, histones, rib, SS-A, Ro-52, Scl-70, and PM-Scl. Often, this takes only a few minutes.

Result:

• ANA favourable outcome: A kind of autoantibody-related illness is indicated. In the following autoimmune diseases, an ANA test is positive: systemic autoimmune rheumatic disease, mainly systemic lupus erythematosus; Sjogren syndrome; mixed connective tissue disease; discoid lupus erythematosus; drug-induced lupus erythematosus; systemic sclerosis; CREST syndrome (calcinosis; Raynaud's phenomenon; oesophagal days.
• The absence of autoimmune disorders is not entirely excluded by ANA negative results
