[Exocrine pancreatic function test by N-benzoyl-L-tyrosyl-p-aminobenzoic acid (author's transl)].

Urinary excretion of p-aminobenzoic acid (PABA) within 6 h after oral administration of N-benzoyl-L-tyrosyl-P-aminobenzoic acid (Peptide-PABA) was measured. In healthy subjects PABA-excretion rate was not different after 150 mg and 1 g Peptide-PABA. PABA-recovery was significantly lower in patients with chronic pancreatitis. Seperation between healthy persons and patients with chronic pancreatic insufficiency was better with 1 g Peptide-PABA.
