What does a nucleolar pattern mean?
A peripheral pattern indicates that fluorescence occurs at the edges of the nucleus in a shaggy appearance; this pattern is almost exclusive to systemic lupus. A speckled pattern is also found in lupus. Another pattern, known as a nucleolar pattern, is common in people with scleroderma.
What does nucleolar pattern mean on an ANA test?
Furthermore, different ANA patterns have been associated with the presence of cancer. ANAs with a homogeneous and speckled immunofluorescence pattern are associated with lack of cancer, while those with a nucleolar pattern are associated with the presence of cancer (15).
Can ANA be positive then negative?
If your ANA was positive and then it tested negative after you started treatment, that does NOT mean you should stop therapy. If you stop treatment, it can lead to symptoms coming back and could cause a flare. FICTION: Only people who are ill will have a positive ANA.
What diseases can be mistaken for rheumatoid arthritis?

What does a nucleolar Ana pattern mean?
Another pattern, known as a nucleolar pattern, is common in people with scleroderma. 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. Additionally, what does a smooth ANA pattern mean?
What are the Anana patterns of nuclear staining?
ANA Patterns – Nuclear Patterns 1 Prominent fine speckled nuclear staining in interphase cells. 2 Consistent strong fine speckled staining of condensed chromatin in mitotic cells. Depending on the serum dilution used, the mitotic chromatin staining may appear homogeneous. 3 Strong staining of nucleolar organizing region (NOR).
What is the nucleolar pattern in systemic scleroderma?
Nucleolar pattern is seen in sera of patients with progressive systemic sclerosis and Sjögren’s syndrome. Centromere pattern is seen in CREST syndrome. Drug-induced lupus (DIL) other collagen diseases: chronic active hepatitis systemic scleroderma
What are the patterns of antinuclear antibody (ANA) titer?
If titer is ≥ 1:80 a titer and pattern will be reported. Patterns reported include Homogeneous, Speckled, Nucleolar, Centromere, and SSA Ro. All positive results are reported with endpoint titers. ANA (antinuclear antibodies) occur in patients with a variety of autoimmune diseases, both systemic and organ-specific.
