What gastrointestinal problems can you see from a blood test?

Blood tests can indicate several gastrointestinal problems by measuring various markers. Elevated liver enzymes may suggest liver disease or bile duct obstruction, while increased levels of bilirubin can indicate liver dysfunction or hemolysis. Additionally, low levels of albumin or elevated white blood cell counts may point to conditions like inflammatory bowel disease or infections. Further interpretation with additional tests is often necessary to pinpoint specific gastrointestinal issues.
