Ds dna full form

The dsDNA blood test is used after a test for ANA has come back positive and the individual in question is exhibiting some of the physical signs and symptoms of lupus. The dsDNA blood test is fairly specific for lupus itself, while the ANA test detects autoimmune disorders. 95% of the people who are eventually diagnosed with lupus will have a positive ANA test. Instead of the immune system, however, the dsDNA test targets genetic materials that are found in each nucleus that could damage tissues and organs. It may be used for an initial diagnosis or it can be ordered for ongoing disease observation. Increase dsDNA results are often seen before a flare-up of lupus symptoms occurs. Those who have strong indicators of kidney damage or chronic inflammation are the most likely to have ongoing testing to observe disease progression. When Is the dsDNA Blood Test Ordered? The symptoms of lupus can be wide-ranging and non-specific to any individual. That’s why the presence of symptoms is accompanied by a series of tests, including the dsDNA blood test, to determine a definitive diagnosis. A low-grade fever, butterfly rash across the face, unusual muscle pain, and symptoms in the joints that are similar to arthritis are all common indications of the presence of lupus. Hair loss, weight loss, tingling or numbers in the feet and/or hands, and a sensitivity to light may also be present. The dsDNA blood test may even be repeated to confirm a negative result if these signs and symptoms a...

Double-stranded DNA (dsDNA) antibodies are systemic lupus erythematosus (SLE)-specific antibodies and are part of the immunology domain of the 2019 European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) classification criteria for SLE (1) as well as a previous guidance on SLE diagnosis.(2) The Crithidia luciliae indirect immunofluorescence test (CLIFT) is widely used as a confirmatory test following a positive dsDNA IgG result obtained by a solid-phase immunoassay due to its structural or analytical specificity.(3-5) The CLIFT (dsDNA) test is indicated in patients who are positive for anti-cellular antibody (also known as antinuclear antibody [ANA]) homogeneous pattern (6) using HEp-2 substrate by indirect immunofluorescence assay (IFA) following a positive result for dsDNA IgG using a solid-phase immunoassay (eg, enzyme-linked immunosorbent assay or multiplex bead assay).(3,4) A positive CLIFT result is usually associated with the presence of moderate-to-high affinity dsDNA IgG antibodies. The CLIFT result may be negative and the immunoassay positive for dsDNA IgG in SLE patients with inactive (remission) disease or in patients with early disease.(3,4,7) Discordant results between CLIFT and solid-phase immunoassays may also be due to differences in the structural specificities of DNA analytes as well as the absence reliable reagents to harmonize available clinical tests.(3,5,8) A minority of SLE patients may test negative using HEp-2 by IFA for ...

Testing for IgG antibodies to dsDNA is indicated in patients positive for anti-cellular antibody (ie, antinuclear antibody: ANA) homogeneous pattern using HEp-2 substrate by indirect immunofluorescence assay (IFA) along with clinical features compatible with SLE.(1,2,8). A minority of SLE patients may test negative using HEp-2 by IFA for nuclear antibodies.(8,9) Testing antibodies associated with HEp-2 IFA cytoplasmic pattern such as ribosomal P IgG autoantibodies may be useful if features of neuropsychiatric disease are present. Alternatively, patients may be tested for Smith, ribonucleoprotein, SSA-52, and SSA-60 antibodies.(8,9) The levels of antibodies to dsDNA may fluctuate with SLE disease activity. Increasing antibody levels may be associated with flares while decline or negative results may indicate response to treatment or disease remission. Measurements of IgG antibodies to double-stranded DNA (dsDNA) are semiquantitative. Slight changes in the levels of these antibodies should not be relied upon to predict changes in the clinical course of patients with systemic lupus erythematosus (SLE). Clinical flares of disease in patients with SLE may not be accompanied by changes in the levels of dsDNA antibodies. Thus, antibody levels alone are not sufficient to guide disease management. Weak-positive results may not correlate with a diagnosis of SLE. Confirmation with Crithidia luciliae indirect immunofluorescence test (CLIFT), which is more specific for SLE, may be usef...
