PT level is 12.8. BBL is scheduled for 7/12. What to do?

I am scheduled to have a BBL July 12, 2016. Nurse assistance told me that my PT came back abnormal and the doctor suggest that I repeat the PT the INR and the PTT all again. I took my labs at lab core and the PT is 12.8 (high). What does this mean and how can I get this corrected to be cleared for surgery? Please help
