I had some blood work done to check my thyroid, due to some hair loss. Thyroid came back normal, but my alt was 201 ast was 80. I am a 41 yr old white female, non drinker, non smoker, not on any oral medications. My dr then drew for hepatitis screen. It was normal. I am scheduled for a liver ultrasound. Other symptoms are fatigue. No pain or signs of gall bladder issues. What else should I look into to see what is causing the high levels.
