An ANA test is considered positive if fluorescence is seen at a titre of 1:40/1:80. Higher titres are more clinically significant as low positives (≤1:160) are found in up to 20% of healthy individuals, especially the elderly. Only around 5% of the healthy population have ANA titres of 1:160 or higher. [8] [53]
Immunofluorescence pattern of SS-A and SS-B antibodies. Produced using serum from a patient on HEp-20-10 cells with a FITC conjugate. Anti-SSA autoantibodies (anti–Sjögren's-syndrome-related antigen A autoantibodies, also called anti-Ro, or similar names including anti-SSA/Ro, anti-Ro/SSA, anti–SS-A/Ro, and anti-Ro/SS-A) are a type of anti-nuclear autoantibodies that are associated with ...
The pattern is the same regardless of how it is imaged, just as if it were a painted pattern. The "size" of the speckles is a function of the wavelength of the light, the size of the laser beam which illuminates the first surface, and the distance between this surface and the surface where the speckle pattern is formed.
The ANA tests for the presence or absence of autoantibodies, while the ENA panel evaluates which proteins in the cell nucleus the autoantibodies recognize. The ENA panel helps diagnosis, distinguish between, and monitor the progression of autoimmune diseases and is performed with a simple blood draw.

The early clinical features of MCTD are nonspecific and may include fatigue, low-grade fever, myalgias, Raynaud phenomenon, swelling of the fingers or hands, arthralgia, esophageal reflux or dysmotility, acrosclerosis (also known as sclerodactyly), mild myositis, and various forms of pulmonary involvement.
ANCA will less commonly form against alternative antigens that may also result in a p-ANCA pattern. These include lactoferrin, elastase, and cathepsin G. [citation needed] When the condition is a vasculitis, the target is usually MPO. [1] However, the proportion of p-ANCA sera with anti-MPO antibodies has been reported to be as low as 12%. [2]
The speckle pattern is a mixture of interference patterns and natural acoustic reflections. [1] These reflections are also described as speckles or markers. The pattern being random, each region of the myocardium has a unique speckle pattern (also called patterns, features, or fingerprints) that allows the region to be tracked. The speckle ...
