Hello! welcome to Health care magic! From the history I gather that your granddaughter has upper abdominal pain and vomiting. The detail of the blood tests if specific and informative, could have been more helpful! The presence of associated symptoms need to be known - fever, stool pattern, jaundice, food habits, intake of medications, etc might give a clue to the diagnosis. The causes may range from anything from a gastritis, food poisoning, enteritis to a serious pathology like acute pancreatitis, acute hepatitis, acute appendicitis, intestinal obstruction, etc. So at present before they hit the diagnosis , all she might be needing is a complete examination, symptomatic treatment and rehydration measures. Hope she gets well soon!!
