The homogeneous pattern is seen when the condensed chromosomes and interphase chromatin stain. This pattern is associated with anti-dsDNA antibodies, antibodies to nucleosomal components, and anti-histone antibodies. There are two speckled patterns: fine and coarse.
HEp-2 cells provide a greater ability to differentiate patterns of ANA than animal sections, due to the large nuclei and high mitotic rate of the cell line. Upon incubation with serum containing anti-dsDNA antibodies and fluorescent labelled secondary antibodies, homogeneous staining of interphase nuclei and condensed chromosomal staining of ...
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 ...
Serology is the scientific study of serum and other body fluids.In practice, the term usually refers to the diagnostic identification of antibodies in the serum. [1] Such antibodies are typically formed in response to an infection (against a given microorganism), [2] against other foreign proteins (in response, for example, to a mismatched blood transfusion), or to one's own proteins (in ...
An extractable nuclear antigen panel, or an ENA panel, tests for presence of autoantibodies in the blood that react with proteins in the cell nucleus.It is usually done as a follow-up to a positive antinuclear antibody test and when one is showing symptoms of an autoimmune disorder.
Nearly half of all women have "dense breasts"—yet countless don't find out until later in life. Dense breasts have more fibrous and glandular tissue relative to fat tissue in the breast. Because ...
This test tells whether there are antibodies in the maternal plasma. If positive, the antibody is identified and given a titer. Titers of 1:4 or higher is considered critical for Kell (compared to 1:16 for most other antibodies) and is considered to confer a high risk of fetal anemia. [17]
