“…The CE/MA test procedure has been proposed by Strobel et al (13) as a relatively convenient tool in the study of intestinal permeability and has since been used by other investigators (14‐18). In our laboratory it was reliable with no substantial flaws in healthy children and adults; in diseases such as scleroderma (21), radiation enteritis (19‐20), cancer chemotherapy (23), postcolectomy pouch (24), and in type II diabetes mellitus (30).
