Speckled: Fine and coarse speckles of ANA staining are seen throughout the nucleus. Researchers determined that positive ANA-HEp-2 tests in healthy participants occurred predominantly as a nuclear fine speckled (NFS) pattern (at low to moderate titer) or as a nuclear dense fine speckled (NDFS) pattern (frequently at high titer) in 46% and 33% of ANA-positive healthy individuals, respectively. 1:40, 1:80 or even 1:160), there is often no autoimmune disease.

Titer reading is determined by adding saline (salt water) to a sample of plasma (the protein-rich liquid part of blood) a certain number of times. A clumpy speckled pattern may be seen with antibodies to n-RNP, Sm, and SSB/La. All of this is also regardless of pattern.
