Liver biopsy: PAS:Glycogenated hepatocytes PAS w diastase: no hyaline globules No stainable iron Does this rule out fatty liver or liver disease?

Not all diseases. It rules deposition of iron and carbohydrates. The description does not mention fat. At times biopsy may not contain lesions present elsewhere in the organ. It would be prudent to discuss it with your doctor and better yet with your doctor and the pathologist who reviewed the biopsy.
