title: The effect of test meals on the PED test.
abstract: The effects of test meals on the PFD (pancreatic function diagnostant) test, which was introduced as "the B.T.PABA test" in the previous reports, were studied. The higher the protein in the test meal, the lower the urinary excretion value of p-aminobenzoic acid (PABA) and the first 3-h of PABA excretion. By using a test meal containing protein, the differences in digestion-absorption disorders between gastrectomy procedures (Billroth I and Billroth II) were clarified. Therefore, a test meal which contains a suitable amount of protein should be used in the PFD test to improve diagnostic accuracy.
