Simple tests of small intestinal function not only allow to verify and quantitate malabsorption syndromes, but also permit to make first differential diagnostic decisions which in turn allow to employ more invasive or elaborate techniques on a more rational and restricted base. Essential diagnostic procedures comprise the analysis of fecal wet weight, fecal fat excretion, occasionally of serum beta-carotene concentration, the D-xylose test, the breath-hydrogen test with either lactose or glucose as substrates, the detection of bile acid malabsorption with 75Se-HCAT and of protein-loosing enteropathies by means of the fecal clearance of alpha-1-antitrypsin.

D011504	Protein-Losing Enteropathies	Pathological conditions in the INTESTINES that are characterized by the gastrointestinal loss of serum proteins, including SERUM ALBUMIN; IMMUNOGLOBULINS; and at times LYMPHOCYTES.
