I Have Been Running High Blood Sugar Of 250-300 And

I have been running high blood sugar of 250-300 and have been extremely fatigued with aching on my right side so I went to my PCP on Thursday to be tested for diabetes. She did an A1C and it said I was not diabetic so she sent me home. She called me back later that afternoon and said that my liver count was way off. She said it was 160 and should be in the 40 range. She tested me for Hepatitis A,B, and C and Mono. She called me Monday and said they were all negative. I'm scheduled for an ultrasound in the morning. What could this be? I'm in normal to low weight range for my height, I an a non drinker, I do not do drugs, and I'm a 39 year old female.
