What diseases are associated with speckled ANA?
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.
Does a speckled ANA test mean lupus?
Speckled (tiny dots throughout the nucleus)—a common pattern, not specific, but often indicating anti-Sm or anti-RNP antibodies (see below) found in lupus or mixed connective tissue disease.
What does a fine speckled ANA pattern mean?
The dense fine speckled (DFS) pattern as detected by indirect immunofluorescence (IIF) on HEp-2 cells has been associated with several inflammatory diseases but is most commonly observed in individuals that do not have an antinuclear antibody (ANA)-associated rheumatic disease and even in apparently healthy individuals …
What does a speckled pattern indicate?
Speckled pattern correlates with antibody to nuclear antigens extractable by saline; it is found in many disease states, including SLE and scleroderma. When antibodies to DNA and deoxyribonucleoprotein are present (rim and homogenous pattern), there may be interference with the detection of speckled pattern.

What does a positive ANA with speckled pattern mean?
There are many other kinds of patterns: homogenous, centromere, nucleolar, speckled, rim etc. Each of these patterns possibly indicate the presence of specific nuclear antibodies. For example, the presence of a speckled positive ANA indicates the presence of these specific autoantibodies, SSA, SSB, RNP, Smith, and Ku antibodies.
