Hi hun I don't know where your from. I know different clinics have different ratings. I don't beleive my lab goes over 2560. My ANA stays between 1260 and 2580 weather I feel good or not.
I've always seen them rating multiplied by two.
like40x2=80
80x 2=160
160x2=320
320x2=640
640x2=1280
1280x2=2560.
If I try to go higher I'll have to take my shoes off and count with my toes.
Hope your not feeling to bad.
blessings
