2023年6月23日 · The ENA test is used to help diagnose certain autoimmune diseases. ENA stands for extractable nuclear antigen because these proteins can be taken out (extracted) from the cells in the body.

An ENA (extractable nuclear antigen) panel is a blood test that looks for antibodies that cause your immune system to attack healthy parts of your body. It can help your healthcare provider diagnose or rule out autoimmune diseases.

Extractable nuclear antigens (ENAs) are over 100 different soluble cytoplasmic and nuclear antigens. They are known as "extractable" because they can be removed from cell nuclei using saline and represent six main proteins: Ro, La, Sm, RNP, Scl-70, Jo1.

2025年2月25日 · ENA provides evidence-based emergency nursing resources to support safe practice and care delivery. Includes toolkits, position statements, clinical practice guidelines, and quality and safety resources ready for immediate implementation

2021年11月9日 · Tests for extractable nuclear antigens (ENA) antibodies help distinguish between autoimmune disorders, such as lupus, scleroderma and Sjogren syndrome.

The Journal advances and integrates the mission, vision, and values of the ENA with the current goal to synergize: community, governance and leadership, knowledge, quality and safety, and advocacy.

2024年7月20日 · Antibodies to extractable nuclear antigens (ENAs) are autoantibodies produced when the immune system mistakenly attacks the body’s own tissues. The ENA panel detects …

2024年3月1日 · ENA blood tests are instrumental in identifying specific antibodies associated with lupus, such as anti-dsDNA (anti-double-stranded DNA). The raised levels of these antibodies provide valuable diagnostic clues, assisting in the early detection and management of lupus.

2022年2月10日 · An extractable nuclear antigen (ENA) panel detects the presence of one or more autoantibodies in the blood that react with proteins in the cell nucleus. These proteins are known as "extractable" because they can be removed from cell nuclei using saline.

The ENA panel is usually ordered as a follow-up after a positive ANA (Anti-Nuclear Antibody) test in a person who has signs and symptoms of an autoimmune disease. The ENA panel may be ordered to help make a diagnosis of the following autoimmune disorders: Systemic Lupus Erythematosus (SLE) Mixed connective tissue disease (MCTD) Sjögren’s ...
