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]
Ana Gomes Ferreira (born 29 June 1987), known professionally as Ana Free, [1] is a singer, musician, songwriter and performer who has had a series of top-five hit singles, including 4 number one hits, in Portugal.

Post-streptococcus glomerulonephritis is more often associated with group A strep skin infection than it is with strep pharyngitis, so in a patient with suspected post-strep glomerulonephritis with a negative ASO titer, one can then obtain anti-DNase-B titers which are more sensitive for group A strep and for its various strains.
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.
A viral titer is the lowest concentration of a virus that still infects cells. To determine the titer, several dilutions are prepared, such as 10 −1, 10 −2, 10 −3, ... 10 −8. [1] The titer of a fat is the temperature, in degrees Celsius, at which it solidifies. [4] The higher the titer, the harder the fat.
A titre has significance only if it is greatly elevated (> 200), but a rise in titre demonstrated in paired blood samples taken days apart is more informative for diagnosis. The antibody levels begin to rise after 1 to 3 weeks of strep infection, peaks in 3 to 5 weeks and falls back to insignificant levels in 6 months.
Immunofluorescence pattern of SS-A and SS-B antibodies. Produced using serum from a patient on HEp-20-10 cells with a FITC conjugate. Anti-SSA autoantibodies (anti–Sjögren's-syndrome-related antigen A autoantibodies, also called anti-Ro, or similar names including anti-SSA/Ro, anti-Ro/SSA, anti–SS-A/Ro, and anti-Ro/SS-A) are a type of anti-nuclear autoantibodies that are associated with ...
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.
