What is an ENA 10 panel?

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 does positive ANA and ENA mean?

An ENA panel is ordered when a person has symptoms that could be due to an autoimmune disorder and has a positive ANA test. Signs and symptoms of autoimmune disorders are highly variable and can involve several different areas of the body. They may include: Fever and persistent fatigue.

Can you have lupus with a negative ENA?

It is possible for people with lupus to have a negative ANA, but these instances are rare. In fact, only 2% of people with lupus will have a negative ANA. People with lupus who have a negative ANA test may have anti-Ro/SSA or antiphospholipid antibodies.

What is ENA Ab screening for?

Test Overview : A screening test used for patient with signs and symptoms of connective tissue disorders that includes testing for SS-A/RO, SS-B/LA, SM, RNP/SM, SCL-70 and JO-1.

Is ENA the same as ANA?

The ANA tests for the presence or absence of autoantibodies, while the ENA panel evaluates which proteins in the cell nucleus the autoantibodies recognize. The ENA panel helps diagnosis, distinguish between, and monitor the progression of autoimmune diseases and is performed with a simple blood draw.

What is ENA screen?

An extractable nuclear antigen (ENA) panel detects the presence of autoantibodies in the blood that react with proteins in the cell nucleus.

What is the difference between ENA and ANA?

Can you have a negative ANA and a positive ENA?

Conclusion: ANA negative/ENA positive results, while rare, do occur. It is quite uncommon to have a diagnosis of lupus but does not exclude the possibility of connective tissue disease.

Can ANA be positive and ENA negative?

Can you have an autoimmune disease with a negative ENA?

Anti-ENA-negative patients were diagnosed with an autoimmune disease in 35% of the sample (45/129). Twelve (26.7%) of these patients were diagnosed with SLE, and four (8.9%) patients were diagnosed with SLE associated with another autoimmune disease.

What causes positive ANA?

An ANA panel helps determine the level of ANA in your blood. You may have an autoimmune disorder if the level is high. However, conditions such as infections, cancer , and other medical problems can also result in a positive ANA test.

What’s the difference between Ena vs. ANA tests?

The ANA test evaluates the presence or absence of autoantibodies, while the ENA panel aims to determine to what proteins in the cell nucleus the autoantibodies recognize. If an ANA test is negative, then the person is extremely unlikely to test positive for a specific antinuclear antibody (which is what the ENA panel tests).

What is an ENA panel blood test?

The ENA (extractable nuclear antigen) panel is a blood test that looks for antibodies to 6 or 7 different proteins in the body.

What is an anti ENA panel?

An ENA (Extractable Nuclear Antigen Antibodies) panel detects the presence of one or more specific autoantibodies in the blood. Autoantibodies are produced when a person’s immune system mistakenly targets and attacks the body’s own tissues.
