An ANA test is considered positive if fluorescence is seen at a titre of 1:40/1:80. Higher titres are more clinically significant as low positives (≤1:160) are found in up to 20% of healthy individuals, especially the elderly. Only around 5% of the healthy population have ANA titres of 1:160 or higher. [8] [53]
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. ...
Titres are sometimes expressed by the denominator only, for example 1:256 is written 256. [3] The term also has two other, conflicting meanings. In titration, the titer is the ratio of actual to nominal concentration of a titrant, e.g. a titer of 0.5 would require 1/0.5 = 2 times more titrant than nominal. This is to compensate for possible ...
Titres are monitored more often in cases of more active lupus than that of less active lupus at intervals of 1–3 months and 6–12 months, respectively. [1] Anti-dsDNA antibodies are highly associated with glomerulonephritis in SLE, although some patients with high titers of anti-dsDNA antibodies do not develop renal disease. This is most ...

[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 undocumented immigrant was charged with setting a woman on fire, killing her, as she slept in the New York City subway -- a horrific alleged crime that officials called "beyond comprehension."
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.
