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 ...
Ninety-six percent of patients with lupus induced by procainamide will have a positive test for anti-histone antibodies, and 100% of patients whose lupus was induced by penicillamine, isoniazid, or methyldopa will have a positive test for anti-histone antibodies. In 70% of patients with rheumatoid arthritis, Felty's syndrome, Sjogren's syndrome ...
Immunological criteria: Individuals exhibiting 1) high serum levels of antinuclear antibodies; 2) high serum levels of anti-dsDNA antibodies; 3) high serum levels of anti-Sm antibodies; 4) high blood levels of antiphospholipid antibodies, high blood levels of the lupus anticoagulant, a false positive rapid plasma reagin test, or a medium to ...
Lupus occurs from infancy to old age, with peak occurrence between ages 15 and 40. [20] Lupus affects females in the US 6 to 10 times more often than males. [20] Prevalence data are limited. Estimates vary and range from 1.8 to 7.6 cases per 100,000 persons per year in parts of the continental United States. [20]
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 case of a corrected mixing test, a lower dose of normal pooled plasma is often used, such as a 4:1 mix (4 times as much patient plasma than normal pooled plasma), as some studies suggest that this method is more sensitive for the detection of a weak lupus anticoagulant that is not enough prevalent or potent to affect a 1:1 mix.
When skin not exposed to the sun is tested, a positive direct IF (the so-called lupus band test) is evidence of systemic lupus erythematosus. [101] ANA screening yields positive results in many connective tissue disorders and other autoimmune diseases, and may occur in normal individuals.
the degree of modification of the capillaroscopy test (skin blood vessel study technique) of nail fold during follow-up. the presence of antinuclear antibodies. young age. [21] severe vitamin D deficiency. [22] the presence of anti-dsDNA, anti-Sm and anti-cardiolipin autoantibodies correlates with the development of systemic lupus erythematosus ...
