Determination of the concentration of α1 - antitrypsin in the stool is a diagnostic indicator of inflammatory diseases of the small and the large intestine, especially malabsorption syndrome. α1 - antitrypsin belongs to the family of plasma proteins with antiproteinase effect. α1 - antitrypsin is synthesized in liver, in small amount in macrophage and is a protease inhibitor of serine proteases sercected from neutrophils. α1 - antitrypsin is acute phase protein. Higher α1 - antitrypsin values are in early phase of inflammation associated with raised CRP and other pozitive acute phase proteins. Fecal α1 - antitrypsin clearance is a sensitive and specific marker of protein loss. For α1 - antitrypsin determination in stool samples ELISA method can be used. ELISA is noncompetetive immunoassay used to detect presence of antibody or an antigen in a sample. The aim of this work was to compare two ELISA sets (Immundiagnostik and Ridascreen) used for determination α1 - antitrypsin in the stool. Then examine stability of α1 - antitrypsin in the stool and in extract prepared from stool in various storing conditions temperature and time. After this establish this method as routine in laboratory. 20 patient stool samples were examined to compare ELISA sets. Samples were suggested to be α1 - antitrypsin...
