question: My brother is not feeling well and just received lab reports where is sgot and sgpt levels are extremely high i.e. AST (SGOT) is 48 Range 5-34 ALT (SGPT) is 117 Range 0-55 He does not drink alcohol,take heavy tylenol. He also high creatine levels, been losing weight etc.. everything I read leans toward Hepatitis or some type of poisoning. He also shows signs of Hyperthryoid and has been losing weight even with increase eating. I am concerned he has been exposed to some type of chemical, poison or could it be related to the something else. Should docs test him for Hepatitis? Please let me know other tests they should be running with with these results. 54 year old male, very athletic and lean. A Ultrasound has been scheduled of his Thyroid too. Other symptoms, heart palpitations, dry skin, hair loss throughout top part of hair, evenly and mood swings. Thanks of any help on this.
