Fecal alpha1--antitrypsin in healthy and intestinal-disorder Thai children.

Objective: Determine the normal FA1-AT level in random wet stool of Thai children using RID and NPL, and to study the correlation between RID and NPL methods for measurement of FA1-AT.

Material And Method: Random stool samples were collected from healthy children and intestinal-disorders patients. Alpha1-antitrypsin (FA1-AT) in wet stool samples was measured by nephelometry (NPL) and radial-immunodiffusion (RID) methods.
