Anything over 1:40 is positive for autoimmune diseases.
It goes like this:
1:40-weak positive
1:80-weak positive
1:160
1:320
1:640
and double it everytime after that.
The pattern determines the type of autoimmune disease.
Go to Lupus.org and search for the pattern types for a more detail description of the patterns.
