What is ANA blood test?

An antinuclear antibody (ANA) test looks for antinuclear antibodies in a person’s blood. ANAs are a type of antibody called an autoantibody, and, like other antibodies, they are produced by the immune system.

What is ANA immunoassay screen?

An ANA test detects antinuclear antibodies (ANA) in your blood. Your immune system normally makes antibodies to help you fight infection. In contrast, antinuclear antibodies often attack your body’s own tissues — specifically targeting each cell’s nucleus.

What is in an ANA panel?

This series of tests, commonly called an ANA panel, checks for the following antibodies: anti-double-stranded DNA, anti-Smith, anti-U1RNP, anti-Ro/SSA, and anti-La/SSB. Some laboratories also include other antibodies in their panel, including antinucleoprotein, anticentromere, or antihistone.

What tests are included in ANA profile?

  • What is ANA test called?

    An antinuclear antibody test is a blood test that looks for certain kinds of antibodies in your body. It’s also called an ANA or FANA (fluorescent antinuclear antibody) test. Antibodies are proteins that your immune system makes to fight off bacteria, viruses, and other germs.

    What is ANA speckled?

    Speckled: Fine and coarse speckles of ANA staining are seen throughout the nucleus. This pattern is more commonly associated with antibodies to extractable nuclear antigens. This pattern can be associated with Systemic Lupus Erythematosus, Sjögren’s syndrome, Systemic Sclerosis, Polymyositis, and Rheumatoid Arthritis.

    What are ANA patterns?

    ANAs are defined as having patterns. What does this mean? ANAs present different “patterns” depending on the staining of the cell nucleus in the laboratory: homogeneous or diffuse pattern; speckled pattern; nucleolar pattern; and peripheral or rim pattern.

    How do you read ANA results?

    A positive ANA test is usually reported as both a ratio (called a titer) and a pattern, such as smooth or speckled. Certain diseases are more likely to have certain patterns. The higher the titer, the more likely the result is a “true positive” result, meaning you have significant ANAs and an autoimmune disease.
