[The assessment of the ferritin level in gastroenterological diseases].

Blood serum ferritin levels were measured by indirect hemagglutination test in patients with diseases of the liver, bile duct, and gastrointestinal tract. Ferritin levels were found increased in the majority of patients, though to a different measure. Its concentrations were the highest in patients with virus hepatitis A, cirrhosis of the liver, and reactive nonspecific hepatitis, normalizing in the course of treatment, These data prompt the use of ferritin measurements in the diagnosis, monitoring the course of treatment, and prediction of the outcomes of acute and chronic diseases of the liver, bile duct, and gastrointestinal tract.
