question: Dear Doctor,  Yesterday I have done my Liver Function Test and observed that the SGOT and SGPT are increased to 653 and 1164 respectively. Besides my Bilirubin (Total) is 4.4. During last two months I have been taking Levonorgestrel and Ethinylestradiol tablets for my painful periods. I am suffering from abdominal pain with dark urine and less appetite.    What are possible causes for this abnormal test result? What are the precautions?
