[|AI|]  Hello thank you for your contact to Chat Doctor. If I am your treating doctor I would like to tell you that tidal title of 1:160 or above is considered positive. You have 1:80 title, which I consider it to be negative. But ideal procedure is that you have to count the community title and accordingly the cutoff is to be decided. If you have anything else to know kindly contact me.  Chat Doctor.  Thank you
