Extractable Nuclear Antigens (ENA) Antibodies

What Is an ENA Antibodies Test?

The ENA (Extractable Nuclear Antigen) antibodies test is a specialised blood test used to detect autoantibodies targeting specific proteins found within the nucleus of cells. These proteins are referred to as "extractable nuclear antigens" due to their ability to be isolated from the cell nucleus using laboratory methods.

Purpose of the ENA Antibodies Test

This test is commonly used in the diagnosis and monitoring of autoimmune diseases. The presence of ENA antibodies can indicate disorders where the immune system mistakenly attacks the body’s own tissues.

Conditions Associated with ENA Antibodies

ENA antibody testing helps identify and differentiate between a range of autoimmune conditions, including:

Systemic lupus erythematosus (SLE)

Sjögren’s syndrome

Scleroderma

Mixed connective tissue disease

Polymyositis and dermatomyositis

How the Test Works

A blood sample is taken and analysed for the presence of antibodies against specific nuclear proteins. These results are often used alongside other autoimmune screening tests, such as ANA (antinuclear antibody) tests, for a comprehensive diagnosis.
