ANA test results are most often reported in 2 parts: the level or titer and the pattern. Titres are reported in ratios, most often 1:40, 1:80, 1:160, 1:320, and 1:640. Some, but not all labs will report a titre above 1:160 as positive.

The ANA test gives two types of results: 1) the titre, and 2) the pattern. Result 1: the titre. This part of the ANA test gives an estimate of how many anti-nuclear antibodies are present (i.e. the “titre”). This is done by taking a sample of the liquid part of the blood called the serum and diluting it with a liquid called a diluent.

2024年11月16日 · When interpreting ANA test results, doctors typically look at the titer level and the staining pattern under a microscope. A higher titer, such as 1:160 or above, may indicate a greater likelihood of an autoimmune condition, while lower titers, like 1:40, can be found in healthy individuals or those with non-autoimmune issues.

Anti-Jo-1 for cytoplasmic and anti-U1RNP for nuclear speckled are the only widely available tests for myositis-related autoantibodies. Nuclear speckled patterns with overlapping features of PM/DM and SLE or SSc may be similar in patients with anti-U1RNP (MCTD) and anti-Ku-positive myositis patients. RA
