The speckled pattern in ANA (Antinuclear Antibody) testing is one of the most common and diagnostically significant patterns, characterized by its distinctive, fine or coarse speckled appearance under a fluorescence microscope.
5 Ιαν 2022 · This change results in the overarching nuclear speckled pattern (AC-4,5), classified at the competent-level to represent only the fine-speckled (AC-4) and large speckled (AC-5) patterns, both of which do not stain the mitotic condensed chromatin; this arrangement is more practical as it is consistent with the understanding that many ...
Nuclear speckled pattern with striking variability in intensity with the strongest staining in G2 phase and weakest/negative staining in G1. The centromeres are positive only in prometaphase and metaphase, revealing multiple aligned small and faint dots.
ANA Pattern Nuclear, Speckled. AC-2,4,5,29: Speckled. I understand that 1:40 is very lowly positive to the point where one will write it off as not an autoimmune disease. But if it's only slightly positive, why is there a speckled pattern? What do the AC numbers mean? Thank you for your help
6 Ιουν 2021 · Some patterns, such as nuclear homogenous (AC-1), coarse speckled (AC-5), and centromere (AC-3) IIF patterns are highly associated with disease-restricted autoantibodies and are observed almost exclusively in samples of patients with CTD or individuals with high risk for CTD development.
17 Ιαν 2019 · Scleroderma or systemic sclerosis: ANA pattern is most commonly speckled, followed by centromeric and less commonly nucleolar. Mixed connective tissue disease: ANA pattern is almost always...
The classification tree is a summary of all the consensus patterns based on their main staining feature fitting best to the nuclear, cytoplasmic, or mitotic compartments (figure 2). All 28 ICAP patterns are shown in the classification tree as designated from AC- to AC-28.
