A ratio of 1.2 is commonly used, such that a value <1.2 indicates the absence of a lupus anticoagulant, while a value >1.2 indicates the presence of a lupus anticoagulant. [19] Direct oral anticoagulants and vitamin K antagonists used to treat thrombosis can interfere with lupus anticoagulant assays and generate either false-positive or false ...
A value of greater than 1.5 units relative to a control serum is considered a positive ELISA test for the anti-histone antibodies. Patients with drug-induced lupus erythematosus typically have positive tests for anti-histone antibodies but do not have indications for anti-dsDNA antibodies. Patients with idiopathic systemic lupus erythematosus ...
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
Fresh normal plasma has all the blood coagulation factors with normal levels. If the problem is a simple factor deficiency, mixing the patient plasma 1:1 with plasma that contains 100% of the normal factor level results in a level ≥50% in the mixture (say the patient has an activity of 0%; the average of 100% + 0% = 50%).

Coeliac disease (antibody levels correlate with the level of intestinal damage [8] [9]), autoimmune hepatitis, gastric cancer: anti-CCP: cyclic citrullinated peptide: rheumatoid arthritis: Liver kidney microsomal type 1 antibody: autoimmune hepatitis [10] Lupus anticoagulant: Anti-thrombin antibodies: thrombin: systemic lupus erythematosus ...
The Kell group was named after the first patient described with antibodies to K 1, a pregnant woman named Mrs. Kellacher in 1945. [11] Mrs. Cellano was likewise a pregnant woman with the first described antibodies to K 2. The K 0 phenotype was first described in 1957 and the McLeod phenotype was found in Hugh McLeod, a Harvard dental student ...
Blood tests such as enzyme-linked immunosorbent assay (ELISA) and immunofluorescence are routinely performed to detect anti-dsDNA antibodies in diagnostic laboratories. They are highly diagnostic of systemic lupus erythematosus (SLE) and are implicated in the pathogenesis of lupus nephritis. [1] [2]
In autoimmune disease, anti-apolipoprotein H (AAHA) antibodies, also called anti-β 2 glycoprotein I antibodies, comprise a subset of anti-cardiolipin antibodies and lupus anticoagulant. These antibodies are involved in sclerosis and are strongly associated with thrombotic forms of lupus. [ 1 ]
