ENA Screening

What is ENA Screening?

ENA screening is a blood test that searches for antibodies against specific extractable nuclear antigens. These antigens are involved in the core processes of cells and can be targeted by the immune system in autoimmune diseases. ENA screening helps in identifying antibodies commonly associated with conditions such as systemic lupus erythematosus (SLE), Sjögren's syndrome, and scleroderma.

Why have ENA Screening performed?

ENA screening is crucial for diagnosing various autoimmune diseases. It allows healthcare providers to identify and differentiate specific diseases, which is essential for developing effective treatment and monitoring the progression of the disease over time.

What does it indicate?

The identification of antibodies against specific extractable nuclear antigens can indicate the presence of an autoimmune disease. The specific antibodies found can assist in pinpointing the exact condition the patient has.

What does a positive ENA Screening mean?

A positive ENA screening indicates the presence of antibodies against one or more extractable nuclear antigens, which can be an indication of an autoimmune disease. The specific antibodies detected can provide information about the type of disease.

What does a negative ENA Screening mean?

A negative ENA screening means that no antibodies against extractable nuclear antigens have been detected. This may suggest the absence of the specific autoimmune diseases tested for, though other tests may be required to refine the diagnosis or rule out other conditions.
