Hi, Thanks for writing in. It is important to know if she is having unconjugated or conjugated hyperbilirubinemia. Unconjugated hyperbilirubinemia can develop as a consequence of blood transfusions, underlying hemolytic disorders, resorbing hematomas, drug effects, or Gilbert s syndrome.Treatment is directed toward the underlying condition. Conjugated hyperbilirubinemia can occur as a result of either intrahepatic or extrahepatic disorders. Markedly abnormal aminotransferases and LDH in conjunction with a normal abdominal ultrasound scan suggest ischemic liver injury which can be due to any operative complications like drugs and medications. As ultrasound scan shows no significant findings, please allow the doctors to deal with it slowly and get liver function tests repeated when required.
