One hour blood D-xylose test and the rise of plasma triglyceride levels after fat test meal (TART) as screening tests of malabsorption were measured in two groups of children: 66 patients with coeliac disease and 36 normal controls. In coeliac patients one hour blood D-xylose test resulted pathologic in 83% of the cases (between 21 e 25 mg% are considered dubious values). TART resulted pathologic in a similar percentage. Dividing the patients in two groups according to the age (<3 years and > 3 years) we found that the one hour blood D-xylose test is more valid in patients under 3 years of age while TART resulted more sensitive in patients older than 3 years of age. Both tests have false negatives and false positives. The false positives increased with age. According to their experience the Authors point out the usefulness of more than one screening test to identify the patients that must undergo a biopsy.
