My cholesterol results....

I just got my results this morning over the phone. My dr. said they were excellent but from what I have read my LDL seems high. Dont know if this matters but I am a 30 yr old female. Ok here it is....Try-64, HDL-54 and LDL 135. Total cholesterol 183. What do you guys think? Should anything be lower/higher???? Shouldnt my LDL be below 100? Thanks. :)
