94098-1Dense fine speckled 70 protein IgG Ab [Presence] in Serum or Plasma by ImmunoassayActive

Term Description

Detection of IgG antibodies against DFS70 (dense fine speckled 70 antigen) in serum or plasma to assist in the diagnosis of autoimmune diseases. The term was created for, but not limited in use to, the submitter's test kit, Euroimmun Anti-DFS70 ELISA (IgG), which calculates the ratio of the extinction value of the control or patient sample over the extinction value of the calibrator. A ratio of greater than or equal to 1.0 is considered positive. A negative serological result does not exclude the presence of disease.

Part Description

LP230331-3   Dense fine speckled 70 protein Ab.IgG
Antinuclear antibodies are essential to diagnose systemic autoimmune rheumatic diseases (SARDs) such as Lupus erythematosus and scleroderma. However, 20-30% of healthy people test positive for ANAs,half of which are dense fine speckled 70 protein (DFS70) antibodies. DFS70 antibodies have been found in patients with various chronic inflammatory diseases but no one disease in particular. It has been suggested that the best use for measuring DFS70 antibodies might be as a biomarker that excludes the diagnosis of SARD since DFS70 antibodies are more often found in patients without active SARD than with it. Antibody titers of DFS70 are highest in healthy young females and the titers decline as a person ages.( http://cli-online.com/featured-articles/anti-dfs70-antibodies-detection-and-significance/) Source: Regenstrief LOINC
