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]

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 ...
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 ...

The ANA tests for the presence or absence of autoantibodies, while the ENA panel evaluates which proteins in the cell nucleus the autoantibodies recognize. The ENA panel helps diagnosis, distinguish between, and monitor the progression of autoimmune diseases and is performed with a simple blood draw.
