What is Extractable Nuclear Antigens test?
An extractable nuclear antigen (ENA) panel detects the presence of 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 and represent six main proteins (Ro, La, Sm, RNP, Scl-70 and Jo1).
What is an ENA blood test for?
The 4-test ENA panel is used to help diagnose mixed connective tissue disease (MCTD), lupus (SLE), and Sjögren syndrome. The 6-test ENA panel can also help identify scleroderma and polymyositis/dermatomyositis.
What is ANA 11?
DESCRIPTION. The ANA Multiplex w/ Reflex to 11 Antibody Cascade test, is commonly ordered in association with diagnosis and treatment rheumatic autoimmune disorders such as Systemic Lupus Erythematosus (SLE) and Sjorgen Syndrome.
What is ENA in rheumatology?
An extractable nuclear antigen panel, or an ENA panel, tests for presence of autoantibodies in the blood that react with proteins in the cell nucleus. It is usually done as a follow up to a positive antinuclear antibody (ANA) test and when one is showing symptoms of an autoimmune disorder.
Is dsDNA and ENA?
Autoantibodies to nuclear antigens, i.e. antinuclear antibodies (ANA), antibodies to double-stranded DNA (dsDNA) and extractable nuclear antigens (ENA), are useful as diagnostic markers for a variety of autoimmune diseases.
What is anti ENA screen?
An anti-ENA screen is usually prescribed following a positive result in an antinuclear antibody (ANA) test. While the ANA test suggests the presence of an autoimmune disorder, an anti-ENA panel makes it possible to distinguish between many different collagen diseases.
What does a positive ENA Ab screening mean?
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)

What is the difference between Sjogren’s A and B?
SS-A antibodies are found in approximately 60-80% of Sjögren’s syndrome patients. SS-B antibodies are less common, being found in approximately 30-50% of Sjögren’s syndrome patients. SS-A antibodies thus occur commonly by themselves. However, it is very uncommon for SS-B antibodies to occur alone.
What is dsDNA and Ena testing?
What is dsDNA crithidia Luciliae IFA?
DNA (ds) Antibody, Crithidia IFA with Reflex to Titer – dsDNA Antibody is detected in patients with active systemic lupus erythematosus (SLE) and approximately 20% of patients with mixed connective tissue disease.
