I would think that if it is not detected that it is negative. I think that the ANA titer has to be greater then 1:80 to be considered positive. I am not sure, but I think I saw that in a post. Saysusie and Oluwa would have a better answer I am sure. I know my titer was 1:360 and speckle patterned and they said that it was positive. I hope that I have helped in some way here.
